No need to panic. IMO, Fable 5 wasnโt worth it for most tasks, not to mention costs and the nerfing.
Opus 4.8 (planning) and GPT-5.5 (execution) still takes the crown.
As a result of a US government directive, we are suspending access to Claude Fable 5 for all users. You can continue to use all other Claude models.
Hereโs what this means for you:
Across Claude products, new sessions will run on your selected default model or Opus 4.8, and existing Fable 5 sessions will end with an error.
On the Claude Platform, requests to Fable 5 will also return an error. Please update your integrations to other Claude models.
We know this is a disruption to your workflows; we appreciate your patience and support.
