Elevated errors on many Claude models

This incident has been resolved.

Success rates across all models have returned to expected levels. We are continuing to monitor closely to ensure no further issues will recur.

We are continuing to work to resolve issues affecting success rates on Opus 4.7 and 4.8, and will provide additional updates as soon as possible.

We have identified the issue and we are working to mitigate the issue. Current ongoing issues with frontier models are with Opus 4.7 and Opus 4.8 and other models have recovered.

We are currently investigating this issue.
