@RobertCraigie , can you take a look?

Looks like you've got type checking errors.

I think this isn't quite correct as well, I think it should be this instead so that we don't always have to update this for every response_format.

        model = cast(
            "str | Transcription",
            get_client().audio.transcriptions.create(
                file=(args.file, buffer_reader),
                model=args.model,
                language=args.language or NOT_GIVEN,
                temperature=args.temperature or NOT_GIVEN,
                prompt=args.prompt or NOT_GIVEN,
                # casts required because the API is typed for enums
                # but we don't want to validate that here for forwards-compat
                response_format=cast(Any, args.response_format),
            ),
        )
        if isinstance(model, str):
            sys.stdout.write("\n" + model + "\n")
        else:
            print_model(model)

And the same applies below as well (replacing Transcription with Translation)
