            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("Sehyo/Qwen3.5-122B-A10B-NVFP4")
model = AutoModelForMultimodalLM.from_pretrained("Sehyo/Qwen3.5-122B-A10B-NVFP4", device_map="auto")

            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
inputs = processor.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)

MTP support in model

I swear I had it working yesterday, but now claude is telling me that there are no MTP weights in your quantization. Could you check if this is true? I'm only getting 11 t/s without MTP.

Same issue. MTP fails in vllm.

Hello, I have had this brought to my attention. I am on holiday but will return home in about 12 hours or so. I will make a patch and re-upload a new revision with MTP included after that.

I already created MTP model weights, which I might fork off of your model to repost, it you don't mind. Upload in progress:

MTP now active, also I have updated PR example script to include MTP weights.

There are pending PR's in vllm to fix MTP tool calling parsers. MTP works with straight chat requests, but tool calling for me shows MTP breaks. Waiting for PRs to be merged to nightly
