Widespread outage hits Claude, ChatGPT, and Grok with errors across Anthropic Opus models and OpenAI Codex
↗
A widespread outage is affecting multiple major AI platforms simultaneously, with Anthropic reporting errors across Opus 4.8 and Opus 5, and OpenAI reporting errors across ChatGPT and Codex, while Grok is also experiencing issues.
Simultaneous outages across multiple independent AI providers mean teams relying on any single provider for production workloads have no fallback within the same class of service. The scope across both Anthropic's Opus models and OpenAI's ChatGPT and Codex suggests the incident may involve shared upstream infrastructure or a correlated failure mode rather than isolated provider issues.
