         Our [actual code](gh-file:vllm/model_executor/models/fuyu.py) has special handling

+    !!! note
+        The `_call_hf_processor` method specifies both `mm_kwargs` and `tok_kwargs` for
+        processing. `mm_kwargs` is used to both initialize and call the huggingface
+        processor, whereas `tok_kwargs` is only used to call the huggingface processor.

     This lets us override [_get_mm_fields_config][vllm.multimodal.processing.BaseMultiModalProcessor._get_mm_fields_config] as follows:
