Update

We are experiencing degraded availability for the Gemini (2.5 Pro, 2.0 Flash) and Claude (Sonnet 3.7, Sonnet 4, Opus 4) models in Copilot Chat, VS Code and other Copilot products. This is due to an issue with an upstream model provider. We are working with them to resolve the issue.

Other models are available and working as expected.

Update

We redirected requests for Claude 3.7 Sonnet to additional partners and users should see recovery when using that model. We still are experiencing degraded availability for the Gemini (2.5 Pro, 2.0 Flash) and Claude (Sonnet 4, Opus 4) models in Copilot Chat, VS Code and other Copilot products.

Update

Gemini (2.5 Pro and 2.0 Flash) and Claude (Sonnet 4 and Opus 4) chat models in Copilot are still experiencing reduced availability. We are actively communicating with our upstream model provider to resolve the issue and restore full service. We will provide another update by 20:15 UTC.

Claude Sonnet 4 and Opus 4 models continue to have degraded availability in Copilot Chat, VS Code, and other Copilot products. Gemini Pro 2.5 and 2.0 Flash are currently unavailable. Our upstream model provider has indicated that they have identified the problem and are applying mitigations.
