# Multi-Modality

```{eval-rst}
.. 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 [supported models](#supported-mm-models)
via the `multi_modal_data` field in {class}`vllm.inputs.PromptType`.

Currently, vLLM only has built-in support for image data. You can extend vLLM to process additional modalities
by following [this guide](#adding-multimodal-plugin).

Looking to add your own multi-modal model? Please follow the instructions listed [here](#enabling-multimodal-inputs).
