Hey @gshevchenko, thanks for the detailed report. The request IDs helped a lot, so let’s go through it piece by piece.
Failure A (AI Model Not Found / BAD_MODEL_NAME, requests 9926f36f-... and 940d0647-...): both reached us without an attached API key (bring_your_own_key false), so the custom ID got rejected. In Settings → Models under OpenAI API Key, double-check that the “Use OpenAI API key” toggle is actually enabled. Pasting the key and turning on the toggle are two separate steps, and Override Base URL only applies while the key is active. If it still fails, delete the key and add it again, then flip the toggle off and on once. This is the same scenario as in this thread: BYOK + Databricks AI Gateway — custom model names rejected ("Model name is not valid")
Failure B (request a2bcc770-... with k3): here the key was attached (byok=true), but the request hit a plan check that shouldn’t apply to a Pro account. This shouldn’t happen, and it’s not something in your setup. I’ve sent it to the team and we’re tracking it. I can’t share a timeline yet.
If Failure A still happens after checking the toggle, please retry and send a fresh request ID. If possible, do it with Privacy Mode turned off for that one request so we can confirm on our side. Let me know how it goes.
