Anthropic's 10,000 seats aren't free compute, they're a distribution channel. Standard seats are free, the premium tier with 5x usage runs $15 a month for a year, but the gate is a PI or equivalent, who then pulls lab members in.
The real money is behind it: up to $50,000 in credits per AI for Science project. But biology and chemistry researchers still only get Opus-class models, and Fable keeps blocking bio and drug-development queries on dual-use grounds. So this isn't open, it's tiered openness — get researchers into Claude's workflow first, keep the sensitive directions locked.
