The VALS AI Science Index ranks GPT-6 Astra and GPT-6.1 Sol at the top among 21 models, yet no model sweeps every field. GPT-6 Astra leads life and mathematical sciences; Claude Sonnet 5.5 tops physical and engineering sciences (and BioMysteryBench); GPT-6.1 Sol leads earth sciences. Claude Opus 5.5 ranks fourth overall and Google's Gemini 4 Argon fifth, falling outside the top five in several disciplines.
