Observation
GitHub serves Grok 4.6 and 4.7 in Copilot beside other models, and an upstream incident sent their error rates up until the provider mitigated it.
- Takeaway
- Keep a second model one click away wherever people work in Grok: when xAI's models degrade, GitHub's answer was to switch users to another model.
- What happened
- GitHub's incident report says Copilot users met elevated error rates on Grok 4.6 and Grok 4.7 between 23:28 and 00:23 UTC on October 27, 2026. GitHub traced it to an upstream model provider, showed in-product warnings on the affected models, and told users to pick another model or Auto until the provider's mitigation held.
“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.”
