Anthropic's Claude Fable 5 has returned after a 19-day suspension linked to US export controls, with the reinstated model arriving alongside tighter safety guardrails, temporary usage limits and claims from some users that it briefly revealed fragments of its intermediate reasoning.
Anthropic said the updated model now uses a new classifier that blocks sensitive requests before they reach Fable 5, warning the safeguard may incorrectly flag some legitimate coding tasks. Subscriber access is also temporarily capped at up to 50% of weekly usage through 7 July, after which additional use moves to pay‑as‑you‑go.
