(multi-modality)=

## Multi-Modality

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`.

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

```{autodoc2-summary}
    vllm.multimodal.MULTIMODAL_REGISTRY
```

### Inputs

User-facing inputs.

```{autodoc2-summary}
    vllm.multimodal.inputs.MultiModalDataDict
```

Internal data structures.

```{autodoc2-summary}
    vllm.multimodal.inputs.PlaceholderRange
    vllm.multimodal.inputs.NestedTensors
    vllm.multimodal.inputs.MultiModalFieldElem
    vllm.multimodal.inputs.MultiModalFieldConfig
    vllm.multimodal.inputs.MultiModalKwargsItem
    vllm.multimodal.inputs.MultiModalKwargs
    vllm.multimodal.inputs.MultiModalInputs
```

### Data Parsing

```{autodoc2-summary}
    vllm.multimodal.parse
```

### Data Processing

```{autodoc2-summary}
    vllm.multimodal.processing
```

### Memory Profiling
