Claude: Due to U.S. government directives, access to Fable 5 is suspended. Users should switch to other models as soon as possible.

Odaily reported that Claude forwarded an announcement from ClaudeDevs stating that due to relevant directives from the U.S. government, all users' access to Fable 5 will be suspended. This adjustment will impact certain workflows, and users need to switch to other models as soon as possible. Currently, in the Claude product series, new sessions will default to running the user's set default model or Opus 4.8, while existing Fable 5 sessions will directly report errors and terminate. Additionally, all API requests for Fable 5 on the Claude Platform will also return errors, and developers need to migrate their integrations to other Claude models as soon as possible.
