Claude Sonnet 4.6 Errors
Claude Sonnet 4.6 is experiencing elevated errors, with the issue identified and a fix being implemented as of April 6, 2025.
Background
- Anthropic's Claude is a major AI assistant product; status.claude.com is its official service-health dashboard, akin to what you'd see for AWS or OpenAI.
- This page reports an "ongoing incident" (a bug or outage) for a specific model version, Claude Sonnet 4.6 — "Sonnet" is Anthropic's mid-tier model line (faster/cheaper than Opus), and "4.6" is a specific release version.
- The incident is titled "Claude Sonnet 4.6 Errors" — meaning the model is producing errors for users instead of functioning normally, which would affect anyone using it via the website, API, or third-party apps built on it.
