#What happened

OpenAI's status page lists an incident titled "Degraded performance in GPT-6.1 Sol Codex and Work mode." The timeline: investigating from 08:10 UTC on Oct 13, 2026; the incident entry posted at 08:18 UTC; at 09:30 UTC the status moved to Monitoring with the note "We have applied the mitigation and are monitoring the recovery." Affected components: Codex Web, Codex API, CLI, VS Code extension, and ChatGPT Work, all showing degraded performance. The status page notes the incident affects ChatGPT and Codex.

#Why it matters

GPT-6.1 Sol is the workhorse model for Codex and ChatGPT Work, so degraded performance hits the exact surface developers and knowledge workers rely on for delegated tasks. The quick move from Investigating to Monitoring suggests a mitigation landed within about 80 minutes, but the incident was still listed as ongoing, so users may still see slow or degraded responses until recovery completes.
