Benchmark Almanac

MedChemBench (OpenAI)

Not in model cards

Models answer chemistry questions from an OpenAI internal set, grouped with OpenAI's life science research evaluations. OpenAI has not published the task format.

Reported in the GPT-5.6 post (Sol 48.3%) and the GPT-6 Astra post (Astra 49.3%). OpenAI omits Claude Fable 5 and 5.1 because they refuse most questions. Format and scoring are guesses.
