Fixed

Model capabilities check: Fixed AttributeError when model metadata capabilities field is None
Previously, when a model's meta.capabilities was None, calling .get() on it would crash
Now the code properly converts None to empty dict before accessing capabilities
Affects models imported from external OpenAI-compatible connections with incomplete metadata

Breaking Changes

N/A

Additional Information

Issue: [PR #1062] [MERGED] Remove extra 'S' in 'ASSISTANT' (#20565)
Applies the same fix pattern used in middleware.py to the get_model_capability() helper in tools.py
Example affected models: XiaomiMiMo/MiMo-V2-Flash and others with capabilities: None in metadata
Workaround of re-saving models in Admin Panel is no longer needed
