Let me confirm, I just tried on digitalocean and I have a similar issue, the last version I published might have issue. Fixing as of now.

oh so those are issues from the provider itself, you get to choose between model the provider advertise for you, meaning:

- you can have models you can not actually use (that gpt-5.3 response) - you can have model non-listed.

Those are all coming from the provider with your API_KEY.
