math0_sft

d125m (134.1M parameters) on GSM8K + MATH worked solutions, trained on RTX 3060 12GB (Home GPU). Started 1 Oct 2026, ended 1 Oct 2026.

Hypothesis

Fine-tuning MATH0 on worked solutions (the GSM8K and MATH training sets) teaches it to solve grade-school word problems.

What we learned

Partly: GSM8K exact match 2.43% (32 of 1,319) vs 0.91% before. It learned the answer format (1,308 of 1,319 answers end in one) but not the arithmetic. At 125M the limit is reasoning, not format.

Scores

Higher is better on the headline; change against the parent run, MATH0.
