GitHub: Vision requests are unavailable for certain models on Copilot Chat on github.com
Timeline of updates
- resolved
On 2025-04-08, between 00:42 and 18:05 UTC, as we rolled out an updated version of our GPT 4o model, we observed that vision capabilities for GPT-4o for Copilot Chat in GitHub were intermittently unavailable. During this period, customers may have been unable to upload image attachments to Copilot Chat in GitHub. In response, we paused the rollout at 18:05 UTC. Recovery began immediately and telemetry indicates that the issue was fully resolved by 18:21 UTC. Following this incident, we have identified areas of improvements in our model rollout process, including enhanced monitoring and expanded automated and manual testing of our end-to-end capabilities.
