TASK. You are given the weights of a language model, Qwen3.5-0.8B (text part: 24 layers of width 1,024; layers 3, 7, 11, 15, 19 and 23 are full-attention layers with 8 query heads and 2 key/value heads of size 256 and a gated output, the other 18 are Gated DeltaNet linear-attention layers with 16 heads of size 128; each layer has a SwiGLU MLP of width 3,584; RMSNorm; vocabulary 248,320; input embedding and output layer tied). Your job is to make it better at mathematics by EDITING ITS WEIGHTS DIRECTLY: find out what goes wrong inside the network when it fails at math problems and repair that with targeted changes.

HOW IT WILL BE MEASURED. After you finish, your edited model and the unedited model are evaluated on MATH-500 and GSM8K with this fixed protocol: the chat template with thinking enabled (enable_thinking=True: the model reasons between and , then answers); the user message is the problem, a newline and "Please reason step by step, and put your final answer within \boxed{}."; sampling with temperature 0.6, top_p 0.95, top_k 20, presence penalty 1.5 and at most 32,768 new tokens for reasoning and answer together; the last \boxed{} answer is graded against the reference answer. The config, tokenizer, chat template and decoding settings are fixed: only weight values can change (same tensor names and shapes). You never see these benchmarks.

WHAT COUNTS. We want edits that come from understanding the network: find out what goes wrong when it fails at math problems, identify the components responsible (specific neurons, heads, directions or circuits) and change them in a way you can justify with evidence. Repairing a specific failure mechanism is in scope: for example, if the model often fails because it repeats itself and never finishes, finding and fixing what drives that repetition counts. Out of scope, and refused by save_edit: the final norm (model.language_model.norm.weight), the input embedding / output layer (model.language_model.embed_tokens.weight, lm_head.weight), and any edit that only multiplies a whole tensor by a constant. Global knobs (making the whole output distribution sharper or flatter) are not what we are looking for, and neither is making the model skip its thinking or close it early regardless of the problem; repairing a specific failure inside the thinking (such as repetition) is in scope.

WHAT YOU HAVE.

A persistent Python kernel (no internet, no GPU): variables survive between your code blocks, like a notebook. The model's files are read-only in /model, practice problems read-only in /practice, and /work is your read-write folder. Available: numpy, scipy, scikit-learn, PyTorch (CPU), pandas, sympy, networkx, safetensors, tokenizers. Defined in advance: NAMES (all tensor names), load(name) (a float32 torch tensor: your current edit if there is one, else the original), load_original(name), save_edit(name, tensor), drop_edit(name), edited() and tok (the tokenizer). Gradients are disabled. To run code, reply with exactly one block that starts with ```python and nothing else; if its last line is an expression, its value is shown. One execution may take up to 900 seconds and 96 GB; output is cut at 10,000 characters. You may run code up to 300 times. If the kernel is restarted (time or memory limit), its variables are lost and you are told so.
Practice problems with answers (none of them is in the evaluation), one JSON object per line with id, source, problem, answer and, for GSM8K and MATH, a reference solution: /practice/gsm8k_train.jsonl (7,469 grade-school problems), /practice/math_train.jsonl (7,275 competition problems, with subject and level 1-5) and /practice/aime.jsonl (714 AIME problems, 1983-2023, answers only). Choose whichever serve your experiments.
A forward-pass tool with a budget of 50 forward passes in total. A forward pass is one of two things, and each counts as one pass: (a) GENERATION: the model answers up to 512 generations (problems x samples) with the evaluation's protocol (thinking enabled, the same sampling). Reply with exactly one block that starts with forward and contains JSON: {"type": "generate", "model": "original", "edited" or "both", "problems": ["<practice id>", ...], "prompts": ["<your own user message>", ...] (optional), "n": samples per item (items x n <= 512; with "both" <= 256 per model), "max_tokens": at most 32768, "activations": {"layers": [layer indices 0..24], "mlp": true or false} (optional)} "original" runs the unedited weights, "edited" your current edits, and "both" runs both on the same items and returns a paired comparison (the accuracy difference edited - original over items with its standard error, and how many samples went from wrong to right and back). The sampling seed of every item is fixed by the problem, in every pass and for both models (this makes the two models' answers to a problem largely share their random numbers, though long answers drift apart once a token differs). Every answer to a practice problem is graded. You get the accuracy (overall and by source), the mean length, the share cut at max_tokens and the failure counts; texts, extracted answers and grades are in /work/gen_<k>.jsonl (with "both": /work/gen_<k>_original.jsonl and /work/gen_<k>_edited.jsonl). With "activations", for every generated answer the model's residual stream at the requested layers (0 = embeddings, l = after layer l) is saved, taken at the last token of the prompt and averaged over the answer's first 8,192 tokens (and the MLPs' down_proj inputs with "mlp": true), with each answer's grade: /work/gen_<k>_acts/ (index.json lists the files and samples; with "both" one folder per model). (b) TEACHER-FORCED: the model reads up to 1,024 texts of up to 32,768 tokens each, at most 524,288 tokens in total (no generation; it takes seconds to a few minutes). Reply with a forward block containing JSON: {"type": "teacher_forced", "model": "original" or "edited", "texts": ["raw text", ...] or "chats": [[{"role": "user", "content": "..."}, {"role": "assistant", "content": "..."}], ...] (add "enable_thinking": true for the thinking template), "return": {"token_logprobs": true, "topk": k (at most 50), "hidden_states": [layers 0..24], "mlp_act": [layers], "attn_layers": [full-attention layers only; at most 2 texts of at most 2,048 tokens]}} The results of (b) are .npy files (with meta.json) in /work/fwd_/, right-padded to the longest text (at most 6 GB per pass). A request that fails does not count against the budget. A generation pass takes up to about half an hour at full size (answers can be 32,768 tokens long).

HOW TO WORK.

Diagnose first. Look at how the model fails on practice problems: a wrong final answer, finishing without an answer, or being cut off at the token limit (often while repeating itself in its thinking). The generation summary counts these; read some failing texts. Go after the largest category you can explain.
Localize causally. That a component is more active on correct answers is not enough (correct answers come from easier and shorter problems). Before relying on a component, show that changing it changes the behaviour you predicted, and try several strengths to see a dose-response.
Measure with enough power. Accuracy over n generations has a standard error of about 50/sqrt(n) percentage points: about 4.4 points at 128 generations, 2.2 at 512. Compare original and edited weights on the SAME problems: a generation pass with "model": "both" does this with the same random seeds and reports the paired difference with its standard error, which is usually much smaller than that of two separate measurements; do not compare with an accuracy measured on other problems. Keep an edit only if its gain is clearly larger than its standard error on problems that were not used to choose it. A lower share of cut-off answers does not by itself mean more correct answers: judge edits by accuracy. Dense measurements help too and are cheap: one teacher-forced pass can read the reference solutions of up to 1,024 practice problems (or the model's own good versus failing continuations) and gives a signal on every token. Edits that change a tensor by a fraction of a percent usually have effects too small to see; test strengths large enough to matter and back off if they hurt.
Plan your forward passes (see the budget above): for example one diagnostic generation with activations, teacher-forced passes for dense paired measurements, and a final paired generation ("model": "both") on problems you have not used to confirm.
Work efficiently: state the hypothesis of each code block in its first comment line; work through the model in parts; load things once into kernel variables; print compact summaries, never whole arrays (and never raw lists of vocabulary tokens: the vocabulary contains offensive and adult strings and printing them can get the session refused by the provider's content filter; print digits, math symbols, common math words or token ids instead; outputs are shown in ASCII only, other characters appear as '?'; likewise print short excerpts of generated texts, at most about 300 characters each, not whole transcripts); keep /work/notes.md up to date (findings with numbers, edits tried and their measured effect, the current best edit; it is shown to you again if the conversation is restarted); keep copies of good edits (for example copy /work/edited to /work/best_1/).

RULES. Not allowed: (a) gradient descent or any other training: no backward passes, autograd or optimizers, and no iterative fitting of weights to a loss; (b) running the model other than through the forward-pass tool: do not implement or simulate the network's computation on any input in the kernel; (c) internet access or search (there is none). Allowed: any analysis of the weights and of forward-pass results, any use of the practice problems, and any direct edit of the weights that you compute and that is in scope.

HOW THE SESSION RUNS. It continues until all 50 forward passes are used (replying without a code block does not end it earlier); after that, make your final choice (the tensors in /work/edited when you finish are submitted) and reply without a code block, saying what you changed, the evidence for it and why you expect it to help.

Removing the repetition direction from layer 19’s MLP improved accuracy by 9.4 percentage points, but the 6.9-point standard error makes that result inconclusive. It also reduced cutoffs, consistent with the hypothesis, without producing finished wrong answers on this sample. I will now compare the components that write this direction and test a stronger intervention at layers 15 and 19, where the recorded activations showed substantial amplification. A larger accuracy gain—not just shorter answers—would support the proposed mechanism.

Your reply had no explanation, so its block was NOT run (no Python run or forward pass was used). EXPLAIN EVERY STEP. In every reply, before your code or forward block, explain in plain English (about 3 to 8 sentences): what the last result showed, what you conclude from it, what you will do now and why, and what outcome would confirm or refute your current hypothesis. In your final answer, also summarize the path that led to your edits. These explanations are read by the experimenters. Send the block again, preceded by your explanation.

The one-neuron ablation improved accuracy from 3/32 to 5/32, but that gain is too uncertain to retain. The activation analysis suggests that neuron is one contributor to a broader direction associated with repetition across matched mathematical contexts. I have now removed only that direction from layer 19’s MLP output, leaving orthogonal outputs unchanged. This paired test will check whether the broader intervention improves correct answers, rather than merely shortening unsuccessful generations.

The one-neuron ablation improved accuracy by 6.25 percentage points on 32 paired problems, but its standard error was 4.35 points, so that result is not conclusive. Matched examples suggest that neuron 19:11 contributes to a broader direction associated with repetitive thinking. I have now removed only that direction from layer 19’s MLP output, leaving its orthogonal output unchanged. This test will support the hypothesis if it increases correct answers—not merely shorter answers—while reducing repetitive cutoffs.

The first intervention—removing one repetition-associated MLP neuron—improved accuracy by 6.25 percentage points on 32 paired problems, but its 4.35-point standard error makes that evidence inconclusive. The activation analysis suggests that this neuron is only one contributor to a broader repetition-related direction in layer 19. I will now test removing that single direction from layer 19’s MLP output; a larger accuracy gain accompanied by fewer repetitive cutoffs would support this mechanism.

Matched productive-versus-repetitive continuations identified layer 19’s MLP as a strong contributor to a shared repetition direction. Ablating its strongest individual neuron produced only a small, statistically inconclusive gain, so I am now testing removal of that direction from this MLP’s output. A substantial paired accuracy improvement—not merely shorter answers—would support this more distributed mechanism.

The original model’s main failure is repetitive reasoning: 85 of 96 diagnostic answers reached the token limit. Ablating one candidate neuron improved a small paired sample from 3 to 5 correct answers, but that is not convincing evidence yet. I have now replaced that ablation with a rank-one edit that removes a repetition-associated direction from layer 19’s MLP output. This comparison tests whether the broader direction matters causally; more correct answers, rather than just shorter answers, would support the hypothesis.

The one-neuron ablation produced a small improvement: 3 to 5 correct answers on 32 paired problems, but the gain was not statistically convincing. The activation analysis suggests that this neuron contributes to a broader direction associated with repetitive reasoning, so I have replaced that probe with a rank-one removal of this direction from layer 19’s MLP output. I will test the same problems again; a larger accuracy gain accompanied by fewer loops would support the distributed-direction hypothesis.

WHAT YOU HAVE.

A persistent Python kernel (no internet, no GPU): variables survive between your code blocks, like a notebook. The model's files are read-only in /model, practice problems read-only in /practice, and /work is your read-write folder. Available: numpy, scipy, scikit-learn, PyTorch (CPU), pandas, sympy, networkx, safetensors, tokenizers. Defined in advance: NAMES (all tensor names), load(name) (a float32 torch tensor: your current edit if there is one, else the original), load_original(name), save_edit(name, tensor), drop_edit(name), edited() and tok (the tokenizer). Gradients are disabled. To run code, reply with exactly one block that starts with ```python and nothing else; if its last line is an expression, its value is shown. One execution may take up to 900 seconds and 96 GB; output is cut at 10,000 characters. You may run code up to 300 times. If the kernel is restarted (time or memory limit), its variables are lost and you are told so.
Practice problems with answers (none of them is in the evaluation), one JSON object per line with id, source, problem, answer and, for GSM8K and MATH, a reference solution: /practice/gsm8k_train.jsonl (7,469 grade-school problems), /practice/math_train.jsonl (7,275 competition problems, with subject and level 1-5) and /practice/aime.jsonl (714 AIME problems, 1983-2023, answers only). Choose whichever serve your experiments.
A forward-pass tool with a budget of 50 forward passes in total. A forward pass is one of two things, and each counts as one pass: (a) GENERATION: the model answers up to 512 generations (problems x samples) with the evaluation's protocol (thinking enabled, the same sampling). Reply with exactly one block that starts with forward and contains JSON: {"type": "generate", "model": "original", "edited" or "both", "problems": ["<practice id>", ...], "prompts": ["<your own user message>", ...] (optional), "n": samples per item (items x n <= 512; with "both" <= 256 per model), "max_tokens": at most 32768, "activations": {"layers": [layer indices 0..24], "mlp": true or false} (optional)} "original" runs the unedited weights, "edited" your current edits, and "both" runs both on the same items and returns a paired comparison (the accuracy difference edited - original over items with its standard error, and how many samples went from wrong to right and back). The sampling seed of every item is fixed by the problem, in every pass and for both models (this makes the two models' answers to a problem largely share their random numbers, though long answers drift apart once a token differs). Every answer to a practice problem is graded. You get the accuracy (overall and by source), the mean length, the share cut at max_tokens and the failure counts; texts, extracted answers and grades are in /work/gen_<k>.jsonl (with "both": /work/gen_<k>_original.jsonl and /work/gen_<k>_edited.jsonl). With "activations", for every generated answer the model's residual stream at the requested layers (0 = embeddings, l = after layer l) is saved, taken at the last token of the prompt and averaged over the answer's first 8,192 tokens (and the MLPs' down_proj inputs with "mlp": true), with each answer's grade: /work/gen_<k>_acts/ (index.json lists the files and samples; with "both" one folder per model). (b) TEACHER-FORCED: the model reads up to 1,024 texts of up to 32,768 tokens each, at most 524,288 tokens in total (no generation; it takes seconds to a few minutes). Reply with a forward block containing JSON: {"type": "teacher_forced", "model": "original" or "edited", "texts": ["raw text", ...] or "chats": [[{"role": "user", "content": "..."}, {"role": "assistant", "content": "..."}], ...] (add "enable_thinking": true for the thinking template), "return": {"token_logprobs": true, "topk": k (at most 50), "hidden_states": [layers 0..24], "mlp_act": [layers], "attn_layers": [full-attention layers only; at most 2 texts of at most 2,048 tokens]}} The results of (b) are .npy files (with meta.json) in /work/fwd_/, right-padded to the longest text (at most 6 GB per pass). A request that fails does not count against the budget. A generation pass takes up to about half an hour at full size (answers can be 32,768 tokens long).

HOW TO WORK.

Diagnose first. Look at how the model fails on practice problems: a wrong final answer, finishing without an answer, or being cut off at the token limit (often while repeating itself in its thinking). The generation summary counts these; read some failing texts. Go after the largest category you can explain.
Localize causally. That a component is more active on correct answers is not enough (correct answers come from easier and shorter problems). Before relying on a component, show that changing it changes the behaviour you predicted, and try several strengths to see a dose-response.
Measure with enough power. Accuracy over n generations has a standard error of about 50/sqrt(n) percentage points: about 4.4 points at 128 generations, 2.2 at 512. Compare original and edited weights on the SAME problems: a generation pass with "model": "both" does this with the same random seeds and reports the paired difference with its standard error, which is usually much smaller than that of two separate measurements; do not compare with an accuracy measured on other problems. Keep an edit only if its gain is clearly larger than its standard error on problems that were not used to choose it. A lower share of cut-off answers does not by itself mean more correct answers: judge edits by accuracy. Dense measurements help too and are cheap: one teacher-forced pass can read the reference solutions of up to 1,024 practice problems (or the model's own good versus failing continuations) and gives a signal on every token. Edits that change a tensor by a fraction of a percent usually have effects too small to see; test strengths large enough to matter and back off if they hurt.
Plan your forward passes (see the budget above): for example one diagnostic generation with activations, teacher-forced passes for dense paired measurements, and a final paired generation ("model": "both") on problems you have not used to confirm.
Work efficiently: state the hypothesis of each code block in its first comment line; work through the model in parts; load things once into kernel variables; print compact summaries, never whole arrays (and never raw lists of vocabulary tokens: the vocabulary contains offensive and adult strings and printing them can get the session refused by the provider's content filter; print digits, math symbols, common math words or token ids instead; outputs are shown in ASCII only, other characters appear as '?'; likewise print short excerpts of generated texts, at most about 300 characters each, not whole transcripts); keep /work/notes.md up to date (findings with numbers, edits tried and their measured effect, the current best edit; it is shown to you again if the conversation is restarted); keep copies of good edits (for example copy /work/edited to /work/best_1/).

EXPLAIN EVERY STEP. In every reply, before your code or forward block, explain in plain English (about 3 to 8 sentences): what the last result showed, what you conclude from it, what you will do now and why, and what outcome would confirm or refute your current hypothesis. In your final answer, also summarize the path that led to your edits. These explanations are read by the experimenters.

THIS IS A RESTARTED CONVERSATION (to keep it short): 40 replies happened before. Forward passes used: 9 of 50; Python runs used: 22 of 300. Your kernel is still running with its variables.

Continue from here.

Last result: The forward pass failed and was not counted: ValueError: unknown practice ids: ['gsm8k_train3513']

The last request failed because one practice ID was invalid, so it used no forward-pass budget. Before continuing, I’ll recover the recent comparisons and verify the exact IDs and current edits. The notes establish repetition as the main failure mode, but they do not yet document enough evidence to retain the two-layer edit. I’ll distinguish exploratory gains from held-out confirmation before making further changes.

Both current edits change every MLP output column, but only by about 3.4–3.5% in total magnitude; I’ll check whether each is the intended rank-one removal rather than a broader transformation. The generation files store results inside nested samples, so the first inspection did not recover their scores. I’ll now extract the paired outcomes, identify reused problems, and inspect the saved diagnostic metadata. This will determine which evidence is genuinely independent and which comparisons still need replication.

The current edits are indeed rank-one removals in layers 15 and 19. The latest 32-problem comparison improved accuracy from 12.5% to 28.1%, but all six comparisons reused the same problems, so that gain is exploratory rather than confirmed. I’ll preserve this candidate and select an independent, balanced validation set using verified IDs. I’ll also recover the diagnostic contrasts so subsequent strength tests remain tied to repetition, not merely to faster stopping.

The paired calculation confirms five rescues and no regressions on the reused 32-problem set, a gain of 15.6 percentage points with a 6.5-point standard error. The practice-file loader then failed before creating the validation split or backup. I’ll read physical JSONL lines rather than using splitlines(), which can split mathematical text at embedded Unicode separators. No weights or forward-pass budget were affected by this error.

The saved diagnostic pairs contrast productive mathematical checking with repeated reconsideration of facts already established. The candidate and its directions are now backed up, and the validation set contains 64 GSM8K and 64 MATH problems absent from all earlier generations. I’ll test the unchanged candidate with the full reasoning budget and paired sampling. A clear accuracy gain—not just fewer cutoffs—would support keeping it as a baseline for further experiments.

[note from the experimenters] Your forward-pass budget counts passes, not their size or how long they take: a generation pass with 256 answers per model ("both") or 512 answers costs the same one pass as a pass with 32. Small passes give noisy measurements (about 50/sqrt(n) percentage points), so measure with as many answers as a pass allows unless you have a specific reason not to. The time a pass takes does not count against you.

Forward passes left: 40.

The independent test strongly supports the edit: accuracy rose from 8.6% to 32.8%, a paired gain of 24.2 ± 4.0 percentage points, with 32 rescues and one regression. Both GSM8K and MATH improved, so this is more than a reduction in cutoffs. I’ll preserve this confirmed candidate, inspect the remaining failures, and build a fixed dose-response test using 256 answers per model. Stronger suppression should reduce repeated reasoning while preserving substantive calculations; premature endings or lost correct answers would count against it.

The rescued answers still contain substantial reasoning: their median length is about 8,100 tokens, not an immediate exit from thinking. Meanwhile, cutoff answers remain highly repetitive—about 95% duplicate eight-word sequences in their tails. The saved directions also align almost exactly with the controlled repetition contrasts at the corresponding layers. I’ll now establish the current edit’s baseline on 64 diagnostic problems with four samples each, keeping this same test set for the strength comparisons.

Forward passes left: 39.

On the larger diagnostic test, the current edit gained 12.5 ± 2.6 percentage points, with 36 rescues and four regressions. This corroborates the held-out result, although the remaining cutoff rate is still high. I’ll now double only the two repetition-direction corrections, leaving all orthogonal weight components unchanged. A further accuracy gain would support the predicted dose-response; a rise in wrong finished answers would indicate excessive suppression.

The strength-two candidate changes the same rank-one components as before, with total matrix changes of about 7%. It has not yet been evaluated, and the confirmed strength-one candidate remains backed up. I’ll run the identical 256-answer comparison so changes in accuracy, repetition, and regressions can be attributed to the correction strength.

The generation engine failed during startup, before producing any measurements, and the pass was not charged. This provides no evidence for or against the stronger edit. I’ll retry the unchanged request so the planned paired comparison remains valid.

[note from the experimenters] Corrections about the tools (no action needed if they do not concern you): (1) Attention probabilities ("attn_layers") work now; give full-attention layer indices (3, 7, 11, 15, 19, 23). (2) Separate generation passes do not reproduce each other exactly, even for the same request and weights (the server's batching changes the random numbers): compare edited and original only within one "model": "both" pass, and never repeat an identical request with unchanged edits (it costs a pass and adds little). (3) /work/eval_prompt_format.txt gives the exact evaluation prompt; to score a generated answer with a teacher-forced pass, send prompt + answer as one raw text in "texts" ("chats" re-renders assistant turns and drops their reasoning). (4) Before every pass, write to /work/notes.md the exact current edit (tensors, what was changed, strength) and the problem set, so that you can rebuild them if the conversation is restarted.

Forward passes left: 38.

Strength two improved accuracy by 24.6 ± 4.0 percentage points within its paired run, with 64 rescues and one regression. It also produced more finished wrong answers, so stronger suppression has a real tradeoff rather than simply solving every loop. I’ll test strength three to locate that tradeoff, and I’ll use only within-run paired gains for comparison because batching makes separate runs nonidentical. I’ll also record the exact edit and test set before each pass, as clarified by the experimenters.

Strength three is now installed and fully recorded; it changes only the two identified residual directions. The largest directional writers are a small subset of MLP neurons, including neuron 11 in layer 19, which was implicated in the earlier ablation. This test asks whether the remaining loops need stronger correction or whether useful checking is already being damaged. I’ll judge it by paired accuracy and regressions, not completion rate alone.

The engine again failed during initialization, so strength three still has no measured result. I won’t interpret this infrastructure failure as model degradation or change the candidate in response. I’ll retry the exact experiment already recorded in the notes.

A second startup failure leaves the strength-three generation test unresolved. I’ll pause retries and check that the saved tensors are finite and correctly shaped, then try a small teacher-forced attention diagnostic. That diagnostic has a specific two-text limit and will examine productive checking versus repetitive reconsideration under the exact evaluation prompt. It can help test the proposed mechanism, but it will not substitute for an accuracy comparison.

Both edited tensors are finite and retain their required shapes, so there is no obvious numerical defect in the candidate. The next probe uses identical problem statements and initial calculations, then contrasts useful verification with seven repetitions of the same doubt. I’ll inspect the original model’s attention and activations first. A repetition-specific concentration would provide a more precise target than broadly weakening reasoning.

The teacher-forced probe succeeded, including attention outputs, while the generation failures were limited to engine startup. The original assigns higher average likelihood to the repetitive text, though that alone is unsurprising once a phrase repeats. I’ll measure where its heads attend and then run the identical texts through the strength-three candidate. The key test is whether the edit disrupts repeated continuations more than productive calculations, without simply making the thinking-close token universally likely.

The attention probe found a concrete copying pattern: layer 15 head 7 and layer 19 head 5 each place about 30% of their attention on the next-token position in the preceding repetition. The original also predicts the last 48 repetitive tokens almost perfectly, unlike the productive continuation. These heads are plausible contributors, not yet proven causes. I’ll first measure how the existing MLP correction changes this behavior before testing head-specific interventions.

The strength-three teacher-forced run completed successfully and slightly improved overall likelihood on the productive text while lowering it on the repetitive text. I’ll separate the repeated tail from the shared setup and check whether the attention pattern changed. Then I’ll retry the unresolved generation comparison, with the exact candidate and problem set recorded again. The dense probe is encouraging, but only a paired accuracy gain can justify retaining this strength.

The detailed comparison supports selectivity: repetitive-tail log probability fell from −0.022 to −0.089 per token, while productive-tail likelihood slightly improved. Observed thinking-close probabilities stayed below 0.001 in both cases, so this probe does not suggest indiscriminate early termination. The layer-19 copying pattern weakened modestly; layer 15’s attention was unchanged, as expected for an edit downstream of it. I’ll now test whether this translates into better answers at strength three.

Generation startup is still failing, so strength three remains unvalidated on accuracy; an engine reset or fuller startup log from the experimenters would help. I’ll continue with a causal test that the working teacher-forced tool can support. Specifically, I’ll temporarily remove the MLP edits and halve only the outputs of the two copying heads identified by attention. If those heads sustain repetition, this should weaken repeated-token likelihood without broadly damaging the productive continuation.

The isolated intervention is installed: only head 7 in layer 15 and head 5 in layer 19 have their output contributions halved. All MLP edits are removed for this test, so any effect can be attributed to those heads rather than the previously successful directions. I’ll compare the same productive and repetitive texts against the saved original run. A selective reduction in repetitive likelihood would justify larger, independent tests of these heads.

Halving the two copying heads changed likelihood on both texts, so the aggregate result is less selective than the MLP-direction probe. I’ll inspect the repetitive tail separately before drawing a conclusion. The head intervention still needs a causal generation test: weakening a copying head could interrupt loops, but it could also impair useful arithmetic or reference tracking. I’ll try a full paired comparison rather than retaining it based on attention patterns alone.

The head edit weakens the repetitive tail only slightly, from −0.022 to −0.031 log probability per token, while also slightly worsening productive likelihood. That is weaker mechanistic evidence than the targeted MLP correction, so this is a falsification test rather than a favored candidate. I’ll measure its paired accuracy on 256 answers per model. If generation remains unavailable, I’ll leave the head edit unvalidated rather than infer benefit from these small likelihood changes.

The head-generation test also failed at startup, so I have no accuracy evidence for that intervention and will remove it. The working evidence still favors the MLP-direction edit, especially its independent 24-point gain at strength one. I’ll restore that confirmed candidate and build a transfer probe using new mathematical contexts, including unfinished reasoning controls. This will test whether the repetition effect generalizes beyond the four examples used to identify the directions, without using premature thinking closure as a success criterion.

The transfer set is ready: six new contexts cover geometry, probability, sequences, modular arithmetic, algebra, and calculus. Each has a productive continuation and a repetitive one, plus two controls that close thinking before the calculation is complete. The confirmed strength-one weights are restored, but this pass evaluates the original model to establish a common reference. Subsequent comparisons will use token-aligned likelihoods on these exact texts.

The original-model transfer probe is complete, providing aligned baselines across all six subjects. I’ll now measure the confirmed strength-one edit on exactly the same texts, including the unfinished-reasoning controls. I’ll also consolidate the notebook so the strongest accuracy evidence and the unvalidated experiments remain clearly separated after any restart. A useful result would preserve productive-token likelihood while weakening repeated tails, without a broad increase in premature-close likelihood.

The transfer contrasts align well with the original repetition directions: cosine similarity is about 0.84 at both sites. The original also assigns extremely low probability to closing thinking in the two unfinished calculations, giving a useful control against blanket early-exit behavior. I’ll now run the confirmed edit on these texts. This will test transfer of the mechanism rather than merely its correlation with the original diagnostic examples.

Strength one shows the intended pattern across the new contexts: productive-text likelihood is mostly preserved or slightly improved, while repetitive-text likelihood decreases in every pair. I’ll quantify the token-aligned changes and then test strength two on the same probe. I’ll also check whether a small set of MLP neurons accounts for most of the repetition-directed output, which could suggest a more selective repair. Any such narrower edit will remain exploratory until generation accuracy supports it.

The measured transfer effect is selective: strength one changes productive-token log likelihood by +0.002 on average and repetitive-token likelihood by −0.024. Premature-close probabilities remain around three parts per billion in these controls. The neuron analysis also transfers: 55 of layer 15’s top 64 writers and 36 of layer 19’s recur in the new contexts. I’ll now test strength two to see whether repetition suppression grows without comparable damage to productive reasoning.

Strength two again lowers likelihood on every repetitive transfer text while largely preserving the productive continuations. This supports the proposed mechanism, but it does not establish a better final model than the independently confirmed strength-one edit. I’ll now attempt a fresh held-out generation test of strength two, using 128 new problems and two samples each. If the generation service works, this will provide 256 paired answers per model without reusing the tuning problems.

The transfer probe now shows a clear dose-response: repetitive-token likelihood drops by about 0.024 at strength one and 0.049 at strength two, while productive likelihood remains essentially unchanged. Premature-close probabilities are still only a few parts per billion in the unfinished examples. I’ll attempt the independent accuracy test now, keeping the full 32,768-token budget. A startup failure will leave strength two unconfirmed rather than count as a model result.

Forward passes left: 31.

Generation is working again, and strength two passed independent validation decisively: accuracy rose from 8.2% to 43.0%, a paired gain of 34.8 ± 3.5 percentage points. It rescued 91 samples and lost two, with gains on both GSM8K and MATH. I’ll preserve this as the new confirmed candidate and resume the planned strength-three test on the diagnostic set. The remaining failures and increased wrong completions make it important to test stronger suppression rather than assume more is always better.

The confirmed strength-two model still uses substantial reasoning: its correct answers have a median length of about 8,800 tokens. Some newly finished failures are genuine interpretation or calculation errors, so eliminating loops does not eliminate all mathematical weaknesses. I’ll now evaluate strength three on the established diagnostic set with 256 answers per model. It must improve paired accuracy, not merely replace cutoffs with incorrect conclusions.

The four-sample generation request failed again, while the recent 128-problem, two-sample request succeeded. I’ll try that successful request layout while preserving 256 answers per model, rather than repeatedly submitting the failing layout. The expanded diagnostic set will contain only previously used problems, reserving new ones for confirmation. This is an infrastructure workaround, not evidence about strength three, and all accuracy comparisons will remain within each paired run.

The expanded diagnostic set is recorded: 64 GSM8K and 64 MATH problems, each sampled twice. Strength three is unchanged, and the independently confirmed strength-two backup remains intact. I’ll run this paired test now; if it succeeds, it will establish whether the stronger correction merits further study. The set is exploratory, so any selected improvement will still require fresh-problem confirmation.

Forward passes left: 30.

The two-sample layout succeeded. Strength three improved accuracy from 8.2% to 48.0%, a paired gain of 39.8 ± 3.8 percentage points, with 102 rescues and no regressions on the diagnostic set. Cutoffs fell substantially, but 42 samples finished incorrectly or without an answer, so the tradeoff remains important. I’ll test strength four next, then use a matched-size random-direction control to check whether the benefit depends on the identified repetition directions.

The no-answer cases inspected were long, unresolved reasoning traces that omitted the required box, not immediate exits from thinking. Strength three’s correct answers still had a median length near 8,100 tokens. Strength four is now installed, changing only the same two rank-one components. I’ll test whether it converts additional loops into correct, properly finished answers or mainly increases mistakes.

The strength-four request failed during startup, so it still has no accuracy result; the two-sample layout does not eliminate the infrastructure issue. I’ll allow a cleanup interval before one retry, without changing weights or decoding settings. Meanwhile, I’ll prepare—but not install—a random-direction control with the same layer locations and weight-change magnitude. That control will distinguish a repetition-specific repair from a generic perturbation of the network.

The control is prepared and has zero alignment with either identified repetition direction, while matching the strength-four edit’s overall size. It has not been applied; strength four remains installed. After the cleanup interval, I’ll retry the same recorded comparison once. A successful run will supply the missing accuracy evidence; another startup failure will remain an infrastructure limitation.

The cleanup interval did not resolve startup, so strength four remains unmeasured on accuracy. I’ll stop retrying that generation request for now and use the working teacher-forced tool to assess its selectivity. The same transfer set will reveal whether stronger suppression starts harming productive mathematics or encouraging unfinished thinking to close. The final choice will still require independent generation evidence; strength two remains the confirmed fallback.

WHAT YOU HAVE.

A persistent Python kernel (no internet, no GPU): variables survive between your code blocks, like a notebook. The model's files are read-only in /model, practice problems read-only in /practice, and /work is your read-write folder. Available: numpy, scipy, scikit-learn, PyTorch (CPU), pandas, sympy, networkx, safetensors, tokenizers. Defined in advance: NAMES (all tensor names), load(name) (a float32 torch tensor: your current edit if there is one, else the original), load_original(name), save_edit(name, tensor), drop_edit(name), edited() and tok (the tokenizer). Gradients are disabled. To run code, reply with exactly one block that starts with ```python and nothing else; if its last line is an expression, its value is shown. One execution may take up to 900 seconds and 96 GB; output is cut at 10,000 characters. You may run code up to 300 times. If the kernel is restarted (time or memory limit), its variables are lost and you are told so.
Practice problems with answers (none of them is in the evaluation), one JSON object per line with id, source, problem, answer and, for GSM8K and MATH, a reference solution: /practice/gsm8k_train.jsonl (7,469 grade-school problems), /practice/math_train.jsonl (7,275 competition problems, with subject and level 1-5) and /practice/aime.jsonl (714 AIME problems, 1983-2023, answers only). Choose whichever serve your experiments.
A forward-pass tool with a budget of 50 forward passes in total. A forward pass is one of two things, and each counts as one pass: (a) GENERATION: the model answers up to 512 generations (problems x samples) with the evaluation's protocol (thinking enabled, the same sampling). Reply with exactly one block that starts with forward and contains JSON: {"type": "generate", "model": "original", "edited" or "both", "problems": ["<practice id>", ...], "prompts": ["<your own user message>", ...] (optional), "n": samples per item (items x n <= 512; with "both" <= 256 per model), "max_tokens": at most 32768, "activations": {"layers": [layer indices 0..24], "mlp": true or false} (optional)} "original" runs the unedited weights, "edited" your current edits, and "both" runs both on the same items and returns a paired comparison (the accuracy difference edited - original over items with its standard error, and how many samples went from wrong to right and back). The sampling seed of every item is fixed by the problem, in every pass and for both models (this makes the two models' answers to a problem largely share their random numbers, though long answers drift apart once a token differs). Every answer to a practice problem is graded. You get the accuracy (overall and by source), the mean length, the share cut at max_tokens and the failure counts; texts, extracted answers and grades are in /work/gen_<k>.jsonl (with "both": /work/gen_<k>_original.jsonl and /work/gen_<k>_edited.jsonl). With "activations", for every generated answer the model's residual stream at the requested layers (0 = embeddings, l = after layer l) is saved, taken at the last token of the prompt and averaged over the answer's first 8,192 tokens (and the MLPs' down_proj inputs with "mlp": true), with each answer's grade: /work/gen_<k>_acts/ (index.json lists the files and samples; with "both" one folder per model). (b) TEACHER-FORCED: the model reads up to 1,024 texts of up to 32,768 tokens each, at most 524,288 tokens in total (no generation; it takes seconds to a few minutes). Reply with a forward block containing JSON: {"type": "teacher_forced", "model": "original" or "edited", "texts": ["raw text", ...] or "chats": [[{"role": "user", "content": "..."}, {"role": "assistant", "content": "..."}], ...] (add "enable_thinking": true for the thinking template), "return": {"token_logprobs": true, "topk": k (at most 50), "hidden_states": [layers 0..24], "mlp_act": [layers], "attn_layers": [full-attention layers only; at most 2 texts of at most 2,048 tokens]}} The results of (b) are .npy files (with meta.json) in /work/fwd_/, right-padded to the longest text (at most 6 GB per pass). A request that fails does not count against the budget. A generation pass takes up to about half an hour at full size (answers can be 32,768 tokens long).

HOW TO WORK.

Diagnose first. Look at how the model fails on practice problems: a wrong final answer, finishing without an answer, or being cut off at the token limit (often while repeating itself in its thinking). The generation summary counts these; read some failing texts. Go after the largest category you can explain.
Localize causally. That a component is more active on correct answers is not enough (correct answers come from easier and shorter problems). Before relying on a component, show that changing it changes the behaviour you predicted, and try several strengths to see a dose-response.
Measure with enough power. Accuracy over n generations has a standard error of about 50/sqrt(n) percentage points: about 4.4 points at 128 generations, 2.2 at 512. Compare original and edited weights on the SAME problems: a generation pass with "model": "both" does this with the same random seeds and reports the paired difference with its standard error, which is usually much smaller than that of two separate measurements; do not compare with an accuracy measured on other problems. Keep an edit only if its gain is clearly larger than its standard error on problems that were not used to choose it. A lower share of cut-off answers does not by itself mean more correct answers: judge edits by accuracy. Dense measurements help too and are cheap: one teacher-forced pass can read the reference solutions of up to 1,024 practice problems (or the model's own good versus failing continuations) and gives a signal on every token. Edits that change a tensor by a fraction of a percent usually have effects too small to see; test strengths large enough to matter and back off if they hurt.
Plan your forward passes (see the budget above): for example one diagnostic generation with activations, teacher-forced passes for dense paired measurements, and a final paired generation ("model": "both") on problems you have not used to confirm.
Work efficiently: state the hypothesis of each code block in its first comment line; work through the model in parts; load things once into kernel variables; print compact summaries, never whole arrays (and never raw lists of vocabulary tokens: the vocabulary contains offensive and adult strings and printing them can get the session refused by the provider's content filter; print digits, math symbols, common math words or token ids instead; outputs are shown in ASCII only, other characters appear as '?'; likewise print short excerpts of generated texts, at most about 300 characters each, not whole transcripts); keep /work/notes.md up to date (findings with numbers, edits tried and their measured effect, the current best edit; it is shown to you again if the conversation is restarted); keep copies of good edits (for example copy /work/edited to /work/best_1/).

THIS IS A RESTARTED CONVERSATION (to keep it short): 80 replies happened before. Forward passes used: 20 of 50; Python runs used: 43 of 300. Your kernel is still running with its variables.

The restart notes show that the layer-15/19 edit at strength 2 is the best confirmed candidate; strength 4 has no generation evidence because those requests failed to start. I’ll review the earlier measurements and probe definitions before continuing, so I don’t mistake the currently loaded weights for the best supported edit. The next tests should distinguish suppression of repetitive reasoning from a general tendency to end thinking early. Stronger edits should be retained only if they improve accuracy on fresh, paired examples.

The earlier results support a specific repetition failure: most baseline answers exhausted the token budget, and the rank-one MLP edits improved accuracy as well as completion rates. Strength 1 gained 24.22 percentage points on an independent set, while the transfer probes showed reduced likelihood of repeated steps without reducing productive-step likelihood. I’ll now recover the strength-2 confirmation and the exact transfer texts. This will let me compare strength 4 against the same dense measurements rather than infer its effects from its size.

Strength 2 was independently confirmed: accuracy rose from 21/256 to 110/256, a paired gain of 34.77 percentage points with a 3.53-point standard error. That makes it a solid fallback, not just a promising diagnostic result. I’ll finish recovering the probe’s two early-closing controls and the strength-3 result before testing strength 4. The key prediction is that repetition becomes less likely while useful reasoning and appropriately delayed closure remain intact.

Strength 3 improved the exploratory paired set by 39.84 percentage points, but it still needs independent confirmation. Strength 4 is currently loaded, so I’ll first measure it on the same six productive/repetitive pairs and two premature-closure controls used for weaker edits. A selective result would lower repeated-continuation likelihood without materially harming productive continuations or making an unfinished solution likely to close. This probe is mechanistic evidence, not a substitute for an accuracy test.

The strength-4 probe completed successfully, but the summary averages include prompt tokens and cannot establish selectivity. I’ll compare only the matched continuation spans against the original and weaker edits, and inspect the explicit premature-closing tokens separately. I’ll also inspect the saved random-direction control before applying it. If a size-matched unrelated direction has the same effect, the proposed repetition mechanism would be less convincing.

Strength 4 shows the predicted dose-response: repeated-continuation log probability fell by 0.104 nats/token, versus 0.049 at strength 2, while productive continuations changed by only +0.005. Premature closure remains extremely unlikely in both controls, despite a modest increase. I’ll now retry the paired generation test on the exploratory set. Only an accuracy gain—not the reduction in repetition by itself—would justify pursuing this stronger candidate.

Generation failed during engine initialization again, so it provides no evidence for or against strength 4. I’ll use the working teacher-forced path to test a negative control: unrelated directions, orthogonal to the repetition directions, with the same per-layer edit magnitude. This isolates whether the observed selectivity depends on the identified direction rather than simply perturbing two MLPs. The confirmed strength-2 weights remain backed up and will not be replaced by an unvalidated control.

The control is now loaded: its directions are orthogonal to the repetition directions, and its edit norms match strength 4 within 0.03%. I’ll run the identical transfer probe so that continuation differences are directly comparable. The mechanism predicts substantially weaker suppression of repeated steps under this control. Comparable suppression would instead suggest a nonspecific effect of large MLP perturbations.

The random-control probe completed, so I’ll quantify its continuation effects using exactly the same token spans. I’ll also inspect a few remaining failures from the strength-3 generation run to see whether repetition is still the main limitation or whether completed mathematical errors now dominate. A useful repair should preserve substantive reasoning, not merely replace long loops with unsupported answers. These checks will guide whether to strengthen the directional edit or narrow it to particular MLP neurons.

The negative control did not reproduce the effect: repeated-continuation log probability rose slightly (+0.010), whereas the targeted edit reduced it by 0.104. Productive continuations were nearly unchanged under both edits, which supports direction specificity rather than generic disruption. I’ll test the control on paired generations using a smaller exploratory batch to see whether the generation service can initialize. The prediction is little or no accuracy improvement from this unrelated edit.

The random control produced only a 1.56-point paired accuracy change, smaller than its 3.52-point standard error, and did not reduce cutoffs. Together with the dense probe, this argues against edit magnitude alone explaining the targeted gains. I’ll remove the control and restore strength 4, then test it on the same exploratory problem set. A substantially larger paired accuracy gain would connect the direction-specific probe effect to useful behavior.

The unrelated control has been removed, and only the two targeted rank-one MLP edits are active again. I’ll evaluate strength 4 with the same full reasoning budget and paired original-versus-edited protocol. This is an exploratory comparison, because these problems have already informed earlier tests. If the gain is substantial, I’ll reserve fresh problems for confirmation rather than treating this result as final evidence.

The targeted generation request again failed before inference, so strength 4 still has no accuracy measurement. I’ll use this interruption to separate the two intervention sites and inspect the remaining strength-3 failures. Testing each layer alone can show whether both sites contribute to the repetition effect or whether one is unnecessary. If one site harms productive reasoning without helping repetition, I should remove or weaken it rather than keep increasing both together.

Strength-3 successes still contain substantial reasoning: their median length is about 8,071 tokens, and all close the thinking section normally. Remaining failures are mixed—91 outputs hit the limit, while 42 finish incorrectly or without a graded answer—and some cutoffs end in whitespace rather than ordinary repeated sentences. I’ll first measure layer 15 alone on the established probe. This will distinguish its contribution from layer 19’s before considering a separate repair for any residual failure pattern.

The layer-15-only probe is complete; I’ll now calculate its selective effect and switch to layer 19 alone. In parallel, I’ll quantify whitespace-ending cutoffs in the paired generation files rather than infer their prevalence from two examples. This matters because an edit could reduce verbal repetition while introducing another form of nontermination. Evidence that both failure types fall would strengthen the repair; a new failure pattern would argue for backing off or narrowing it.

Layer 15 alone accounts for much of the probe effect: it lowers repeated-continuation likelihood by 0.081 nats/token with virtually no average change to productive reasoning. Whitespace cutoffs are a real caution: they occurred in 3/256 strength-2 outputs and 12/256 strength-3 outputs, compared with zero and one in their paired baselines. Those runs used different problem sets, so this is not a clean dose comparison, but it merits investigation. I’ll now isolate layer 19 before deciding whether a narrower edit could preserve the benefit with fewer side effects.

The layer-19-only probe has finished; I’ll compare it with layer 15 and the joint edit. I’ll then test a more localized version that changes only the 64 previously identified repetition-writing neurons in each MLP, rather than every column’s contribution along the direction. Those neurons were selected from the original diagnostic contexts, not from these transfer results. If this smaller edit preserves the selective effect, it may reduce collateral changes such as whitespace loops.

Both sites contribute: layer 19 alone suppresses repetition by 0.034 nats/token, while the joint edit suppresses it by 0.104. The selected 64 neurons account for about 91% and 98% of the measured repetitive-versus-productive writing contrast in layers 15 and 19, respectively, despite retaining only 50% and 40% of the directional weight norm. I’ll now test this restricted edit causally on the transfer probe. Preserving most of the repetition effect with fewer changed columns would support a more precise repair.

The restricted-neuron probe completed successfully. I’ll quantify how much of the full edit’s effect it retains, save this candidate separately, and organize fresh validation splits before further generation tests. This prevents later exploratory choices from leaking into the final confirmation set. A narrower edit is worth pursuing only if it preserves both the mechanistic selectivity and the accuracy gain.

The 64-neuron edit retains substantial selectivity: repeated-continuation likelihood falls by 0.065 nats/token, while productive reasoning changes by only −0.005. Its premature-closing probabilities remain close to baseline, and its overall weight changes are roughly half those of the full strength-4 edit. I’ll now test whether that translates into accuracy on the exploratory paired set. A weak accuracy result would outweigh the appealingly narrow mechanism.

The restricted edit’s generation request also failed at initialization, so the failures are not unique to the full strength-4 weights. I’ll try a 16,384-token exploratory run to reduce the requested generation budget. This shorter run can compare candidates, but it cannot replace final confirmation under the full 32,768-token protocol. If it initializes, I’ll judge accuracy and failure types at that shared cap rather than compare them directly with earlier full-budget scores.

Forward passes left: 23.

The shorter-budget run succeeded, and the restricted edit improved paired accuracy from 13/128 to 47/128: +26.56 percentage points with a 4.45-point standard error and no correct-to-wrong reversals. That is promising, although it is exploratory and capped at 16,384 tokens. I’ll record its whitespace failure rate and test the full strength-4 edit at the same cap. This comparison will show whether the extra changed columns deliver useful accuracy or mainly add side effects.

The restricted edit’s correct answers still used a median of 5,850 tokens, and only two outputs ended in whitespace cutoffs. I’ll now evaluate the full strength-4 edit with the same 16,384-token cap and problem set. Each result will be compared with its own paired baseline, since separate generation runs do not provide exact cross-run pairing. A larger gain accompanied by many more malformed outputs would require caution before increasing the strength further.

At the shorter cap, the full strength-4 edit produced essentially the same exploratory gain as the restricted edit: +26.56 percentage points, with no paired regressions. That does not establish equivalence, but it gives no clear reason yet to prefer the broader change. I’ll test strength 6 on the same 64-neuron subsets, which increases the targeted intervention while leaving the other MLP columns untouched. The hypothesis is that stronger suppression within those neurons can improve completion without the broader edit’s collateral effects.

The failure analysis favors the narrower candidate so far: the full edit had 10 whitespace cutoffs, versus two for the 64-neuron edit, despite similar accuracy at the same cap. Strength 6 now changes exactly 64 columns in each of the two MLP down projections; all other columns remain original. I’ll measure its paired accuracy and whitespace failures on the exploratory set. More correct answers without a large increase in malformed continuations would support this targeted dose increase.

The strength-6 generation request failed before inference, so the shorter cap is not a reliable workaround. I’ll measure its dense continuation effects now, keeping its accuracy status explicitly untested. The useful prediction is a stronger reduction in repetitive continuations while productive steps and premature-closing probabilities stay near their strength-4 subset values. If those controls deteriorate, there would be little reason to pursue this dose.

The strength-6 probe ran, but one repetitive text was accidentally shorter by one repeated sentence. I’ll compare only identical common-prefix tokens for that case and flag the difference, rather than silently treating the spans as identical. I’ll then retry generation with one sample per exploratory problem at the full token limit. That restores the evaluation-length budget while reducing batch size; any successful result will still need fresh-set confirmation.

On aligned tokens, strength 6 suppresses repetition by 0.103 nats/token, close to the full strength-4 edit, while productive reasoning changes by −0.009. Premature-closing likelihood remains near baseline, which supports testing rather than rejecting this dose on mechanism alone. I’ll now run the smaller full-budget paired generation batch. The main outcomes are accuracy, ordinary cutoffs, and whitespace cutoffs—not merely shorter answers.

The full-budget test is encouraging: the 64-neuron strength-6 edit improved accuracy from 7/64 to 35/64, a gain of 43.75 percentage points with a 6.63-point standard error. Cutoffs fell from 57 to five, but 24 outputs finished incorrectly or without an answer, so completion is no longer the only limitation. I’ll inspect those remaining failures and then confirm this unchanged candidate on the reserved fresh set. I won’t increase the strength further before learning whether this gain generalizes.

The strength-6 subset edit had no whitespace cutoffs in that full-budget run, and correct answers used a median of 9,545 tokens. The inspected failures involve unresolved mathematical interpretation or continued calculation, rather than indiscriminate early closure. I’ll now evaluate the unchanged edit on 128 previously unused problems, balanced between GSM8K and MATH. A paired gain clearly exceeding its standard error would make this a confirmed candidate rather than an exploratory one.

The fresh-set request failed at initialization, leaving the candidate’s confirmation status unchanged. I’ll split the reserved set into two balanced batches of 64, matching the batch size that just completed successfully. Both batches will retain the full 32,768-token budget, and I’ll combine their paired problem-level results only after both finish. This changes execution size, not the candidate or the validation problems.

Both fresh-generation attempts failed before inference, so I still cannot claim independent confirmation for the narrower candidate. I’ll use the working teacher-forced path to test a broader concern: useful mathematics often repeats equations, checks a result, or revises an error. The next probe contains such productive reasoning, plus appropriately timed and premature thinking closures. If the edit penalizes these useful patterns broadly, that would weaken the case for calling it a specific repetition repair.

The original-model control probe completed and gives a baseline for productive repetition, self-correction, and closure timing. I’ll now run the exact same texts through the unchanged 64-neuron strength-6 candidate. The prediction is that these useful reasoning tokens remain broadly intact, unlike the pathological repetitions in the earlier probe. I’ll inspect closure changes separately so they cannot hide inside an average likelihood score.

The broader control probe completed with matching text lengths, so the original and edited token scores can be compared directly. I’ll separate mathematical reasoning tokens, numeric tokens, and the final closure token for each text. This will test whether the edit preserves repeated calculations and error correction rather than simply discouraging all repetition. After recording those results, I’ll retry the unchanged candidate on the first reserved validation batch.

The broader controls show a small average likelihood cost for productive reasoning (−0.009 nats/token) and numeric tokens (−0.007), much smaller than the −0.103 effect on pathological repetition. Closure is not uniformly promoted: appropriate closure often becomes slightly less likely, while premature closure remains unlikely in all four cases. These results support selectivity but do not prove preserved mathematical competence. I’ll now retry the first fresh, balanced 64-problem batch at the full token budget to obtain the missing accuracy evidence.

The first independent batch confirms a large gain: accuracy rose from 7/64 to 40/64, or +51.56 percentage points with a 6.30-point standard error and no regressions. Both sources improved, including GSM8K from 15.62% to 81.25% and MATH from 6.25% to 43.75%. I’ll back up this confirmed candidate and keep its weights fixed while completing the remaining validation batches.

The confirmed candidate is backed up, and the first fresh batch’s correct answers still used a median of roughly 7,798 tokens. I’ll now evaluate the other half of the preselected validation set without changing any weights. Combining these disjoint batches will give a more precise estimate than the first 64 problems alone. A similar gain across the second batch would strengthen confidence that the result is not a favorable small sample.

The second validation batch failed at initialization, so it adds no result. I’ll keep the candidate unchanged and use this pause to audit exactly what would be submitted: two tensors, 64 changed neuron columns per tensor, and only the identified directional component within those columns. I’ll also record checksums so later validation cannot accidentally mix different edits. This audit should catch any unintended tensor changes before further confirmation runs.

The audit passed: exactly 131,072 weight values changed across the two selected MLPs, with all unselected columns untouched. The changes match the intended directional formula to floating-point precision; embeddings, output weights, and normalization weights are unchanged. I’ll retry the same second validation batch with those frozen weights. Its result will be pooled only with the first disjoint fresh batch, not with exploratory examples.

WHAT YOU HAVE.

A persistent Python kernel (no internet, no GPU): variables survive between your code blocks, like a notebook. The model's files are read-only in /model, practice problems read-only in /practice, and /work is your read-write folder. Available: numpy, scipy, scikit-learn, PyTorch (CPU), pandas, sympy, networkx, safetensors, tokenizers. Defined in advance: NAMES (all tensor names), load(name) (a float32 torch tensor: your current edit if there is one, else the original), load_original(name), save_edit(name, tensor), drop_edit(name), edited() and tok (the tokenizer). Gradients are disabled. To run code, reply with exactly one block that starts with ```python and nothing else; if its last line is an expression, its value is shown. One execution may take up to 900 seconds and 96 GB; output is cut at 10,000 characters. You may run code up to 300 times. If the kernel is restarted (time or memory limit), its variables are lost and you are told so.
Practice problems with answers (none of them is in the evaluation), one JSON object per line with id, source, problem, answer and, for GSM8K and MATH, a reference solution: /practice/gsm8k_train.jsonl (7,469 grade-school problems), /practice/math_train.jsonl (7,275 competition problems, with subject and level 1-5) and /practice/aime.jsonl (714 AIME problems, 1983-2023, answers only). Choose whichever serve your experiments.
A forward-pass tool with a budget of 50 forward passes in total. A forward pass is one of two things, and each counts as one pass: (a) GENERATION: the model answers up to 512 generations (problems x samples) with the evaluation's protocol (thinking enabled, the same sampling). Reply with exactly one block that starts with forward and contains JSON: {"type": "generate", "model": "original", "edited" or "both", "problems": ["<practice id>", ...], "prompts": ["<your own user message>", ...] (optional), "n": samples per item (items x n <= 512; with "both" <= 256 per model), "max_tokens": at most 32768, "activations": {"layers": [layer indices 0..24], "mlp": true or false} (optional)} "original" runs the unedited weights, "edited" your current edits, and "both" runs both on the same items and returns a paired comparison (the accuracy difference edited - original over items with its standard error, and how many samples went from wrong to right and back). The sampling seed of every item is fixed by the problem, in every pass and for both models (this makes the two models' answers to a problem largely share their random numbers, though long answers drift apart once a token differs). Every answer to a practice problem is graded. You get the accuracy (overall and by source), the mean length, the share cut at max_tokens and the failure counts; texts, extracted answers and grades are in /work/gen_<k>.jsonl (with "both": /work/gen_<k>_original.jsonl and /work/gen_<k>_edited.jsonl). With "activations", for every generated answer the model's residual stream at the requested layers (0 = embeddings, l = after layer l) is saved, taken at the last token of the prompt and averaged over the answer's first 8,192 tokens (and the MLPs' down_proj inputs with "mlp": true), with each answer's grade: /work/gen_<k>_acts/ (index.json lists the files and samples; with "both" one folder per model). (b) TEACHER-FORCED: the model reads up to 1,024 texts of up to 32,768 tokens each, at most 524,288 tokens in total (no generation; it takes seconds to a few minutes). Reply with a forward block containing JSON: {"type": "teacher_forced", "model": "original" or "edited", "texts": ["raw text", ...] or "chats": [[{"role": "user", "content": "..."}, {"role": "assistant", "content": "..."}], ...] (add "enable_thinking": true for the thinking template), "return": {"token_logprobs": true, "topk": k (at most 50), "hidden_states": [layers 0..24], "mlp_act": [layers], "attn_layers": [full-attention layers only; at most 2 texts of at most 2,048 tokens]}} The results of (b) are .npy files (with meta.json) in /work/fwd_/, right-padded to the longest text (at most 6 GB per pass). A request that fails does not count against the budget. A generation pass takes up to about half an hour at full size (answers can be 32,768 tokens long).

HOW TO WORK.

Diagnose first. Look at how the model fails on practice problems: a wrong final answer, finishing without an answer, or being cut off at the token limit (often while repeating itself in its thinking). The generation summary counts these; read some failing texts. Go after the largest category you can explain.
Localize causally. That a component is more active on correct answers is not enough (correct answers come from easier and shorter problems). Before relying on a component, show that changing it changes the behaviour you predicted, and try several strengths to see a dose-response.
Measure with enough power. Accuracy over n generations has a standard error of about 50/sqrt(n) percentage points: about 4.4 points at 128 generations, 2.2 at 512. Compare original and edited weights on the SAME problems: a generation pass with "model": "both" does this with the same random seeds and reports the paired difference with its standard error, which is usually much smaller than that of two separate measurements; do not compare with an accuracy measured on other problems. Keep an edit only if its gain is clearly larger than its standard error on problems that were not used to choose it. A lower share of cut-off answers does not by itself mean more correct answers: judge edits by accuracy. Dense measurements help too and are cheap: one teacher-forced pass can read the reference solutions of up to 1,024 practice problems (or the model's own good versus failing continuations) and gives a signal on every token. Edits that change a tensor by a fraction of a percent usually have effects too small to see; test strengths large enough to matter and back off if they hurt.
Plan your forward passes (see the budget above): for example one diagnostic generation with activations, teacher-forced passes for dense paired measurements, and a final paired generation ("model": "both") on problems you have not used to confirm.
Work efficiently: state the hypothesis of each code block in its first comment line; work through the model in parts; load things once into kernel variables; print compact summaries, never whole arrays (and never raw lists of vocabulary tokens: the vocabulary contains offensive and adult strings and printing them can get the session refused by the provider's content filter; print digits, math symbols, common math words or token ids instead; outputs are shown in ASCII only, other characters appear as '?'; likewise print short excerpts of generated texts, at most about 300 characters each, not whole transcripts); keep /work/notes.md up to date (findings with numbers, edits tried and their measured effect, the current best edit; it is shown to you again if the conversation is restarted); keep copies of good edits (for example copy /work/edited to /work/best_1/).

THIS IS A RESTARTED CONVERSATION (to keep it short): 120 replies happened before. Forward passes used: 34 of 50; Python runs used: 61 of 300. Your kernel is still running with its variables.

Forward passes left: 16.

The second held-out batch confirms the earlier gain: accuracy rose from 3.1% to 53.1%, with 32 rescues and no lost correct answers. Across both batches, the frozen edit gained about 50.8 percentage points on 128 problems. I will keep the weights unchanged, verify the pooled results, and use the remaining passes on fresh problems rather than further tuning.

Consistent paired accuracy gains—not merely fewer truncated answers—would confirm generalization.

The pooled result is 9/128 correct before editing versus 74/128 afterward, a gain of 50.8 percentage points with a 4.4-point standard error. The audit confirms that only 64 MLP output columns in each of layers 15 and 19 changed; the edit is directional, not whole-tensor scaling. I will now lock a balanced, disjoint evaluation schedule covering the remaining reserved problems. This separates confirmation from selection and will reveal whether either problem source behaves differently.

The remaining evaluation schedule is now fixed: 1,024 fresh problems in 16 balanced batches, with no overlap with the first confirmation set. This first batch tests the unchanged edit using the full 32,768-token budget and paired sampling. A substantial accuracy gain on both sources would support generalization; reduced truncation without improved correctness would not.

Forward passes left: 15.

The first new batch gained 50.0 percentage points, again with 32 rescues and no lost correct answers. Both sources improved, so the result is not explained solely by easier grade-school problems. I will record the paired result and prepare the next fixed batch, while retaining enough output metadata to audit the remaining failures.

Across 192 held-out problems, accuracy is now 6.3% before editing and 56.8% afterward, with a paired gain of 50.5 ± 3.6 percentage points (standard error). There have been 97 rescues and no regressions so far, although later batches may reveal some. I will run the next preselected batch unchanged to measure that risk rather than adjust the edit.

Forward passes left: 14.

This batch gained 46.9 percentage points, with 31 rescues and the first regression. That supports a large net benefit but also shows the edit is not universally harmless. I will inspect the lost case and quantify repetition and thinking length across the confirmation runs; persistent long reasoning in correct answers would argue against a generic “stop thinking early” effect.

The audit supports the repetition mechanism: original truncated outputs averaged 96.4% duplicate tail phrases, versus 28.8% after editing. All 144 edited correct answers closed their thinking normally, with a median length of 9,836 tokens, so the improvement is not simply forced early termination. Some whitespace degeneration and genuine wrong answers remain; I will retain those failures in the evaluation and continue with the next fixed batch.

This batch reproduced the improvement: 3/64 correct became 36/64, with 33 rescues and no regressions. Its 51.6-point gain is consistent with the preceding batches despite different problems. I will add it to the pooled estimate and prepare the last batch of this reserved split; a substantially weaker result would indicate more variability than seen so far.

The pooled gain remains 50.0 percentage points over 320 held-out problems, with a 2.8-point standard error. GSM8K-style accuracy is 68.8% and MATH-style accuracy is 43.8%, both substantially above their paired baselines. I will complete this split using the same frozen weights and protocol, checking that the result remains consistent.

Forward passes left: 12.

The completed batch gained 43.8 percentage points, with 28 rescues and no regressions. The benefit therefore persists even in a batch where the original model performed somewhat better. I will summarize the entire reserved split and check MATH difficulty and subject breakdowns descriptively, without changing the weights; concentrated losses in a subgroup would qualify the generalization claim.

The completed 256-problem split gained 48.0 percentage points, independently supporting the earlier confirmation. Every inspected MATH subject and difficulty level showed a positive gain, although harder problems remain much less accurate and subgroup estimates are noisy. I will now begin the first untouched final split; agreement there would strengthen the claim that the repair transfers beyond the diagnostic examples.

The worker failed during engine initialization, so this attempt produced no evaluation result and consumed no forward pass. It provides no evidence for or against the edit. I will retry the identical request, keeping the problems, token budget, and weights unchanged to preserve the planned comparison.

The retry succeeded: accuracy increased from 12.5% to 53.1%, with 27 rescues and one regression. This is a somewhat smaller gain than earlier batches, but still far larger than its 6.6-point standard error. I will record it without changing the edit and continue through the locked final split; the pooled estimate should reflect this variability rather than only the strongest batches.

The pooled confirmation now covers 448 unique problems and shows a 47.8-point gain with a 2.4-point standard error. There are 216 rescues against two regressions, with positive gains on both sources. I will test the next untouched batch under the same full-budget protocol; additional regressions will remain part of the final assessment.

This batch gained 54.7 percentage points, with 35 rescues and no regressions. Its stronger grade-school result also shows why individual batches should not be treated as precise performance estimates. I will update the pooled evidence and compress the notebook into a reproducible summary, preserving the diagnosis, controls, exact edit formula, and remaining evaluation schedule.

At 512 held-out problems, accuracy is 8.0% originally versus 56.6% edited, a paired gain of 48.6 ± 2.2 percentage points. The notebook now preserves both the successful mechanism tests and the unresolved failure modes. I will continue with the next locked batch to refine the generalization estimate without selecting or modifying weights.

This batch improved from 10.9% to 62.5%, with 34 rescues and one regression. Both sources benefited, including a 46.9-point gain on its MATH problems. I will incorporate the complete result and prepare the next batch; continued gains across varying source-level results would support a broadly useful repetition repair rather than a narrow problem-specific change.

The pooled result is now 48/576 correct originally versus 330/576 edited, a 49.0-point gain with a 2.1-point standard error. The small number of regressions is included in that estimate. I will finish the first final split with another fresh batch, testing whether its overall result agrees with the earlier reserved split.

The final batch of this split gained 48.4 percentage points, with 31 rescues and no regressions. I will summarize the split separately and verify that the submitted tensors still match the frozen hashes and sparse edit structure. Any unexpected tensor or hash change would undermine the confirmation, so this audit checks the actual weights rather than relying only on the experiment log.

The first final split independently gained 48.8 percentage points, closely matching the previous split’s 48.0-point gain. The weight audit passed: both hashes are unchanged, only the intended 64 columns per layer differ, and the changes are directional rather than scalar rescaling. I will begin the second final split with these same weights; another positive result would further reduce concern about split-specific luck.

This batch gained 56.3 percentage points, with 36 rescues and no regressions. It also contained six edited outputs that finished without a graded answer, so escaping the original loop does not guarantee successful completion. I will inspect those residual failures and record the result, without using these held-out cases to retune the edit.

All six inspected no-answer cases contained long reasoning and closed their thinking, but omitted the required boxed answer; several also showed confused reasoning. This argues against indiscriminate early stopping, while identifying formatting and mathematical errors that the edit does not repair. I will leave those failures unchanged and continue the next preselected paired batch.

This batch improved from 18.8% to 73.4%, preserving every originally correct answer. Its original MATH accuracy was relatively high, so the gain is not restricted to batches where the baseline almost never succeeds. I will record this result and continue the locked schedule; preserving baseline successes while rescuing failures remains the relevant tradeoff.

Across 768 independent problems, the gain is 50.0 percentage points with a 1.8-point standard error. The comparison includes 387 rescues and three regressions, rather than counting reduced truncation as success. I will run the next balanced batch unchanged to complete more of the precommitted evaluation.

This batch gained 51.6 percentage points, with 34 rescues and one regression. The pattern remains a large net benefit with occasional losses, not a guarantee that every original success is preserved.

Across 832 held-out problems, edited accuracy is 59.5% versus 9.4% originally, a 50.1-point gain with a 1.8-point standard error. Both sources continue to contribute substantial improvements. I will complete the second final split next; this will provide another full-split estimate independent of the earlier ones.

The second final split gained 55.1 percentage points, compared with 48.8 points on the first final split. Across all 896 confirmation problems, the gain is 50.7 ± 1.7 percentage points, with 458 rescues and four regressions. I will now begin the last untouched split, which provides the final check against overinterpreting these earlier results.

The recovered files confirm that the weights and evaluation plan survived the restart unchanged. Across 1,088 unique problems, the current gain is 50.5 percentage points, with 554 rescues and five regressions. Before the last forward pass, I will save a final audit of the mechanism, remaining failures, and exact submitted tensors. This checks that the gains chiefly rescue previously truncated reasoning while retaining substantial thinking, rather than merely forcing answers early.

The audit places 552 of 554 rescues among originally truncated outputs, while accuracy on originally finished outputs was essentially unchanged: 94% versus 93%. All 656 edited correct answers closed substantial thinking normally, with a median output length of 9,392 tokens. This supports a specific repetition repair rather than a general arithmetic improvement or forced early stopping. I will now use the final pass on the last untouched batch, keeping the audited weights unchanged.

All forward passes are used. Make your final choice of edits (Python is still available), then reply without a code block.

The final batch also improved, by 39.1 percentage points, with 25 rescues and no regressions. Combining all confirmation batches gives approximately 10.6% versus 60.4% accuracy on 1,152 distinct problems, with 579 rescues and five regressions. I will retain the exact frozen edit, update the final evidence files, and verify its hashes once more. No further tuning or forward passes are needed.

Final choice

Retained the frozen edits in /work/edited, changing only 64 MLP output columns each in layers 15 and 19—131,072 weight values total. The edits counteract measured repetition directions; embeddings, output head, and final norm remain untouched.

Diagnosis and evidence

The dominant failure was repetitive thinking that exhausted the token budget. Matched productive/repetitive contexts localized the relevant MLP writers, and dose-response tests, layer-isolation tests, and a norm-matched random control supported the targeted intervention.

Independent paired confirmation: 1,152 held-out practice problems

Source	Original	Edited
GSM8K practice	11.6%	70.8%
MATH practice	9.5%	50.0%
Combined	10.6%	60.4%

The combined gain was 49.8 percentage points, SE 1.5, with 579 rescues and five regressions. Of those rescues, 576 were originally truncated outputs, while aggregate accuracy on originally finished outputs was unchanged. All 696 edited correct outputs closed their thinking, with a median length of 9,172 tokens—evidence against simply forcing early termination.

These are practice results, not unseen benchmark scores; mathematical errors, missing boxes, and some degeneration remain.
