Solutions

1. Choose a model_name supported by api_family=classic; check get_info() for the valid list.
2. If the model is omni-only, switch api_family to omni and adapt the parameters.

When it happens

Trigger: A model_name that is not in the classic family allowlist is passed with api_family=classic.

Common situations: See trigger scenarios.
