Engine Arguments

Engine arguments control the behavior of the vLLM engine.

For offline inference, they are part of the arguments to LLM class.
For online serving, they are part of the arguments to vllm serve.

The engine argument classes, EngineArgs and AsyncEngineArgs, are a combination of the configuration classes defined in vllm.config. Therefore, if you are interested in developer documentation, we recommend looking at these configuration classes as they are the source of truth for types, defaults and docstrings.
