# Claude Researcher > As of 2026-09-19: Anthropic’s 10,000 scientists-program seats (expanding-support-for-scientists, 2026-08-27) are standard free or premium $15/mo (~5x usage) for one year. Biology and chemistry stay on Opus-class models (Opus 5); Fable 5.1 still blocks professional biology; a seat is not Mythos Glasswing; experiment runners belong at claudescientist.com.
