Update

We are experiencing degraded availability for the Claude Fable 5 model in Copilot products and IDE surfaces. This is due to an issue with an upstream model provider. While we work with them to resolve the issue, we recommend choosing another model or selecting 'Auto' to continue using Copilot.

Update

The issues with our upstream model provider have been resolved, and Claude Fable 5 is once again available in Copilot products and IDE surfaces.

We will continue monitoring to ensure stability, but mitigation is complete.
