Hugging Face's transformers modeling backend for vLLM now matches or exceeds the speed of custom vLLM implementations for many LLM architectures. Harry Mellor and Lysandre demonstrated this across three Qwen3 models. The backend dynamically applies inference-specific layer fusions at runtime, enabling model authors to achieve fast vLLM inference without writing custom code. Compatible models can be served using a single flag.
