The upstream provider continues to return intermittent errors for GPT 5.3 Codex requests. Some users may experience failed or interrupted responses when using this model. Traffic continues to be automatically rerouted to reduce impact, and we are actively working with the upstream provider on a resolution. In the meantime, selecting an alternative model will avoid disruption.

- resolved
Between 06:39 and 18:11 UTC on July 20, 2026, the Copilot service experienced a degradation of the GPT 5.3 model due to an issue with our upstream provider. The upstream model provider returned intermittent errors for GPT 5.3 Codex requests, which caused some responses to fail. Auto mode requests that had selected GPT 5.3 Codex were also impacted. On average about 2% of GPT 5.3 Codex requests failed during this window. Copilot automatically routed eligible traffic away from the impacted provider to reduce customer impact. No other models were impacted. We worked with the upstream provider throughout the incident and confirmed sustained recovery before resolving.
