I think 501 status makes more sense, but not sure if this will break any user code.

I agree. 501 (not implemented) makes more sense. Let's change it.

Suggested change

detail=f"The completions streaming route is not implemented for {self.NAME} models.",

Is not implemented more accurate?

I'm not a big fan of this. Is there a way to enforce the NAME attribute?

Can we use an abstract property instead?

i think abstract property can do. If we don't do any validation, we'll need to rely solely on tests (which are not 100% covered) or get unexpected runtime errors

or set NAME to an empty string in BaseProvider and validate it's overridden in sub classes?
