Hey, thanks for the detailed report.
This is a confirmed bug. When Auto mode routes to a specific model and that model is under high load, the error message doesn’t reflect that you originally picked Auto. So it ends up telling you to “switch to Auto” even though you’re already using it, exactly like you described.
The team is aware of it. Your report, including the exact payload and repro steps, helps us prioritize it, but there’s no ETA on a fix yet.
Workaround: if you hit this, try selecting a specific model manually instead of Auto. That usually avoids the high load routing issue.
A few related threads if you’re curious:
Let me know if anything else comes up.
