ChatGPT users faced elevated error rates this afternoon, with over 12,000 outage reports logged on Down Detector. OpenAI confirmed the main service was restored by 5:14 PM ET, though fine-tuning API issues remain under review.

The disruption impacted both consumer and developer-facing services, raising concerns about reliability during peak usage times. OpenAI is now monitoring recovery efforts after applying backend fixes to stabilize the platform.

Anthropic’s Claude also suffered a separate but similar outage earlier in the day, resolving by early afternoon. These simultaneous failures highlight ongoing infrastructure stress among leading AI platforms as demand surges.

Industry watchers expect more frequent outages as AI models scale, especially without major infrastructure overhauls. Users should monitor status pages for updates if disruptions persist across enterprise tools or third-party integrations.
