Multi-Modality
==============

.. currentmodule:: vllm.multimodal
    
vLLM provides experimental support for multi-modal models through the :mod:`vllm.multimodal` package.

Multi-modal inputs can be passed alongside text and token prompts to :ref:`supported models <supported_vlms>`
via the ``multi_modal_data`` field in :class:`vllm.inputs.PromptInputs`.

Currently, vLLM only has built-in support for image data. You can extend vLLM to process additional modalities
by following :ref:`this guide <adding_multimodal_plugin>`.

Looking to add your own multi-modal model? Please follow the instructions listed :ref:`here <enabling_multimodal_inputs>`.
