Anthropic Fable 5 and Mythos 5 access remains suspended

Category: AI
Status: developing
Sources: Anthropic statement
Summary: Access to Claude Fable 5 and Mythos 5 stays suspended for all customers under the US export control directive issued 2026-06-12, with no restoration as of 2026-06-21. Anthropic's MD International said on 2026-06-18 the company is confident access returns "in coming days," but the directive has not been lifted or narrowed. Other Claude models, including Opus 4.8, are unaffected.
Why it matters: The two flagship models remain unavailable to all customers, so teams that relied on them must keep building on Opus 4.8 and other supported models.
Follow-up: Watch for the directive being lifted, narrowed, or extended, and any official US government statement.
