- Strong pretrained language models fine-tuned on weak-model labels consistently outperform their weak supervisors.
Overstates. The general statement that naive fine-tuning is inadequate for reasoning rests, as far as the comparison with the weak model goes, on one pairing: Gemma-2b supervising Llama2-70b on MATH, 10.0 against 11.6 percent. The paper tested three weak models on two datasets; how the naive baseline fared against the weak model in the other pairings was not read here. The passage is quoted from the body of the paper with an inline citation omitted; it does not appear on the abstract page. Only the method and part of the results were read. Nov 11, 2026

Naive fine-tuning is inadequate for weak-to-strong reasoning. When using Gemma-2b as the weak model on the MATH dataset, full weak fine-tuning underperforms compared to the weak floor (10.0 v.s. 11.6). This indicates that naive fine-tuning, though successfully applied to classification, chess, and reward modeling tasks, falls short for intricate reasoning tasks, particularly those of substantial difficulty like questions in MATH.
