# LLM Deployment using vLLM

Dynamo vLLM integrates [vLLM](https://github.com/vllm-project/vllm) engines into Dynamo's distributed runtime, enabling disaggregated serving, KV-aware routing, and request cancellation while maintaining full compatibility with vLLM's native engine arguments. Dynamo leverages vLLM's native KV cache events, NIXL-based transfer mechanisms, and metric reporting to enable KV-aware routing and P/D disaggregation.

## Installation

### Install Latest Release

We recommend using [uv](https://github.com/astral-sh/uv) to install:

```bash
uv venv --python 3.12 --seed
uv pip install "ai-dynamo[vllm]"
```

This installs Dynamo with the compatible vLLM version.

### Development Setup

For development, use the [devcontainer](https://github.com/ai-dynamo/dynamo/tree/main/.devcontainer) which has all dependencies pre-installed.

<Accordion title="Build and run container">

We have public images available on [NGC Catalog](https://catalog.ngc.nvidia.com/orgs/nvidia/teams/ai-dynamo/collections/ai-dynamo/artifacts). If you'd like to build your own container from source:

```bash
python container/render.py --framework vllm --output-short-filename
docker build -f container/rendered.Dockerfile -t dynamo:latest-vllm .
```

```bash
./container/run.sh -it --framework VLLM [--mount-workspace]
```

## Quick Start

Start infrastructure services for local development:

```bash
docker compose -f deploy/docker-compose.yml up -d
```

Launch an aggregated serving deployment:

```bash
cd $DYNAMO_HOME/examples/backends/vllm
bash launch/agg.sh
```
