same error from Claude Code with API Key: " API Error: Repeated 529 Overloaded errors". Happens only with Opus 4.5. The problem has gone once I switched to default model.

Not subscribing to this issue as we never get official responses to these issues anyway. If anyone finds any example where that in fact happened, let me know 🙃. Also, always wonder if you pay the API directly if you have these issues as well or not..

Still getting API Error: 529 {"type":"error","error":{"type":"overloaded_error","message":"Overloaded"},"request_id":"..."}, even though the status page (https://status.claude.com/) has been showing it's been resolved 2.5 hours ago.
