## From the sources

On August 27th, 2026, between approximately 09:20 and 12:14 UTC, the Copilot service experienced a degradation of the Kimi K3 model due to an issue with our upstream provider. Users encountered elevated error rates when using Kimi K3. No other models were impacted. The issue was resolved by a mitigation put in place by our provider. GitHub is working with our provider to further improve the resiliency of the service to prevent similar incidents in the future.
