Timeline of updates

  1. investigating

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

  2. investigating

    We are experiencing degraded availability for gpt-5.6-sol-fast, gpt-5.6-sol, gpt-6.1-terra, and gpt-6-luna in Copilot products and IDE surfaces. This is due to an issue with an upstream model provider. While we work with them to resolve the issue, we recommend choosing another model or selecting 'Auto' to continue using Copilot.

  3. investigating

    We are in contact with the upstream provider and monitoring as they work towards resolution. For customers who are impacted we recommend choosing another model or selecting ‘Auto’ to continue using Copilot.

  4. investigating

    The upstream provider has made mitigations and we are seeing the affected models begin to recover.

  5. resolvedEdited

    Between 19:05 and 21:27 UTC on November 13, 2026, GitHub Copilot experienced degradation affecting GPT-6.1 Terra, GPT-5.6 Sol, and GPT-6 Luna 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.
