How VLLM load Mistral Pixtral without Huggingface Config File?

[galaxy202411]

I loaded Mistral Pixtral by vllm successfully. It's great.

However, it made me confused that pixtral in HF did not have any HF config file. Please refer to https://huggingface.co/mistralai/Pixtral-12B-2409/tree/main

How VLLM know the model type without any HF config file?

We know to load the repo in Mistral format via the CLI argument --load-format mistral.
