Update

We are experiencing degraded availability for the Haiku 4.5 model 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

Our provider has recovered and we are not seeing errors but we are awaiting a signal from them that the issue will not regress before we go green.

Update

The issues with our upstream model provider have been resolved, and Haiku 4.5 is once again available in Copilot Chat and across IDE integrations.

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