Story

Following its July 1 redeployment, Anthropic's Fable 5 shifted to metered credit billing instead of flat-rate and now requires KYC-style identity verification through Persona. If you're building on the most capable tier, budget for credit costs and an ID gate. Metered access plus verification is a real policy shift for a frontier model, and it's the kind of thing that quietly changes your unit economics.
