Reddit user am17an reports that adding a logit bias against hedging tokens ('wait', 'maybe', 'perhaps') improves quantized Qwen3.5-4B accuracy on a 50-question MATH-500 sample across llama.cpp quantizations, extending a Meta paper's finding to local inference; replication or refutation by other local-inference users would settle whether token-level logit penalties are a practical accuracy knob for quantized models.

Surfaced 2026-09-29T08:09:07Z โ€” Per the Reddit post's citation, a Meta paper found that penalizing hedging tokens like 'wait', 'maybe', and 'perhaps' improves model accurac โ€” Third consecutive velocity_spike is the same cumulative-score artifact (582 pts vs cohort p90 135), not renewed motion: ~1.2 pts/h and ~0.2 comments/h at 39h age, +3 points/+1 comment since the last look, no new evidence, replications, or periphery expansion โ€” the magnitude-valve 'two platforms' reading still counts echo testimony as its second platform. The case's meaning is unchanged (corroborated phenomenon, still single-source training-free trick), so it holds at corroborated/low; the 79th-percentile residual rate is just cohort decay, not a signal worth hours-level attention.

What is this?

A r/LocalLLaMA post by user am17an claims that adding a logit bias against hedging tokens ('wait', 'maybe', 'perhaps') improves quantized Qwen3.5-4B accuracy on a 50-question MATH-500 sample across llama.cpp quantizations, citing a Meta paper that found penalizing hedging tokens improves model accuracy. The supplied snippets do not surface the post itself and do not independently verify the Meta paper โ€” the paper is attested only through the post's own citation โ€” so the claim currently rests on a single first-person report. What the snippets do confirm is the setting: Qwen3.5-4B is a real, actively discussed local model, and r/LocalLLaMA shows a live culture of exactly this kind of token-level llama.cpp hacking (e.g. a parallel logit-bias trick forcing </think> on Qwen3.5) and quantization-accuracy comparison work. Replication or refutation by other users is not yet in evidence.

Why it matters to Scott

Converges with his effort-control canon: a Meta finding (even if only citation-attested) plus a community replication independently back the position his high-not-max and inference-time-scaling pages already lean on โ€” that hedging/backtracking tokens like 'wait' are a cost center whose suppression can raise accuracy โ€” while adding a distinct training-free sampler-level mechanism beside ukisai's trained approach. It bears directly on technologies he actively runs (gamepc's quantized Ollama/llama.cpp serving), making it a one-evening self-replication with proper eval hygiene rather than mere illustration; the n=50 MATH-500 sample and single first-person report are what hold it at medium.
