OPST Mixed Curriculum - GPQA Diamond: leaderboard
OPST v1: Gemma 4 E2B/E4B Base means instruction-tuned; all training methods are separate checkpoints. OPST evaluates EMA teacher, not student. Nonthinking multiple-choice uses answer-option log-likelihood (MMLU 5-shot, other MC zero-shot, length normalization per lm-eval default); thinking parses final Answer: X. GSM8K 8-shot CoT exact numerical match; MATH-500 symbolic equivalence. Training topics and supervision preserved; no unpublished checkpoint URL or decoding settings inferred. GSM8K/MATH-500 use thinking, other tasks do not. Single-domain row combines different specialist checkpoints across columns and is already Table1, so not treated as one model. GPQA Diamond.
