PharmaBench - Mean Score: leaderboard
PharmaBench - Mean Score: Mean rubric score (%). PharmaBench: 120 tasks across eight synthetic drug programs, three runs per task, same unnamed open-source coding agent in an isolated shell/Python/document sandbox without internet. The original eleven-model report uses provider-default reasoning and an unnamed LLM rubric judge; late scoreboard top-up settings are not separately reported. Pass means every required criterion met and no penalty; mean is rubric reward averaged over runs then tasks. Group breakdowns retain the eleven-model report.
Metric: Mean rubric score (%). Source: www.micro1.ai. Saturation forecast: Rough model projection: around 2026. 12 models tracked.
