MinorStatus: resolvedStarted Resolved (42 min)6 updatesstspg.io (opens in new tab)

Affected components: Copilot AI Model Providers

Timeline of updates

  1. investigating

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

  2. investigating

    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.

  3. investigating

    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.

  4. monitoring

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

  5. monitoring

    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.

    We will continue monitoring to ensure stability, but mitigation is complete.

  6. resolved

    Between 08:37 and 09:41 UTC on August 31, 2026, GitHub Copilot experienced degradation affecting several GPT models, including gpt-5.2, gpt-5.3-codex, gpt-5.4, gpt-5.4-mini, gpt-5.4-nano, and the gpt-5.6 family (Luna, Sol, and Terra). Users encountered elevated error rates and interrupted streaming responses. 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.

Archive proof

Rewindex commits each version of an incident it captures to a daily checkpoint, chains it to the day before, and has the checkpoint timestamped by FreeTSA and DigiCert. That proves this record existed by then and has not been changed since, by anyone, Rewindex included.

How the archive is checked, and what it cannot prove.

Impact, status and times are the vendor’s own, as last archived. View on stspg.io (opens in new tab).
