1. 3 Sep 17:11 UTCResolvedBetween 13:22 and 17:11 UTC on September 03, 2026, GitHub Copilot experienced degradation affecting several Grok models, including Grok 4.5 and Grok 4.6. Users encountered elevated error rates, but other models were not affected. The degradation was caused by an issue with an upstream model provider. GitHub engineers detected the issue through automated monitoring, displayed in-product warnings for the affected models, and coordinated with the provider. Service returned to normal after the provider implemented a mitigation.
