## Offline Inference

LLM Class.

Prompt schema for LLM APIs.

- [vllm.inputs.llm][]

## vLLM Engines

Engine classes for offline and online inference.

- [vllm.LLMEngine][]
- [vllm.AsyncLLMEngine][]

## Inference Parameters

Inference parameters for vLLM APIs.

## Multi-Modality

vLLM provides experimental support for multi-modal models through the [vllm.multimodal][] package.

Multi-modal inputs can be passed alongside text and token prompts to [supported models](../models/supported_models.md#list-of-multimodal-language-models)
via the `multi_modal_data` field in [vllm.inputs.PromptType][].

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