- An incident was opened to investigate degraded quality in some Claude model responses.
- Two separate issues were identified and resolved: one affecting Claude Sonnet 4 (Aug 5-Sep 4) and another affecting Claude Haiku 3.5 and Claude Sonnet 4 (Aug 26-Sep 5).
- The issues were caused by unrelated bugs, not intentional degradation due to demand or other factors.
- Fixes have been rolled out for both issues, and the incidents are now resolved.
- Anthropic is continuing to monitor for ongoing quality issues, including reports of degradation for Claude Opus 4.1.
- Community reports were instrumental in identifying and isolating these bugs.
- An update will be shared by the end of the week.
