On September 3 ChatGPT, Claude, and Grok all suffered outages at the same time, with OpenAI citing elevated errors in ChatGPT and Codex, Anthropic listing elevated errors across models including Opus 5 affecting claude.ai, the API, and Claude Code, and xAI reporting a models outage from 9:30am EDT.
