~~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.~~

Between 23:28 and 00:23 UTC on October 27, 2026, GitHub Copilot experienced degradation affecting Grok 4.6 and Grok 4.7 models. Users encountered elevated error rates when using these models. The degradation was caused by an issue with an upstream model provider. GitHub engineers detected the issue through automated monitoring and coordinated with the provider. Our automated model-warning system activated in-product warnings for affected models during the incident. Service returned to normal after the provider implemented a mitigation.
