Input Processing
================

.. currentmodule:: vllm.inputs

vLLM provides a mechanism for defining input processors for each model so that the inputs are processed
in :class:`~vllm.LLMEngine` before they are passed to model executors. 

Currently, this mechanism is only utilized in :ref:`multi-modal models <multi_modality>` for preprocessing multi-modal input 
data in addition to input prompt, but it can be extended to text-only language models when needed.
