GitHub Copilot Degraded Performance - August 31, 2026

We are investigating reports of degraded performance for Copilot AI Model Providers

Copilot is experiencing a higher rate of errors for OpenAI models, including gpt-5.2, gpt-5.3-codex, gpt-5.4, gpt-5.4, and the gpt-5.6 family of models. Other models are not impacted. <br />

One of our model providers has confirmed an incident on their end. We have provided them details to help identify the issue. We are starting to see recovery.

The degradation affecting Copilot AI Model Providers has been mitigated. We are monitoring to ensure stability.

The issues with our upstream model provider have been resolved, and gpt-5.3-codex, gpt-5.4-mini, gpt-5.4-nano, gpt-5.5, and the gpt-5.6 family of models are once again available in Copilot products and IDE surfaces.<br /><br />We will continue monitoring to ensure stability, but mitigation is complete.

This incident has been resolved. Thank you for your patience and understanding as we addressed this issue. A detailed root cause analysis will be shared as soon as it is available.
