## Key Features

The initial release includes the following key features:

- **High-Density LoRA Management**: Streamlined support for lightweight, low-rank adaptations of models.
- **LLM Gateway and Routing**: Efficiently manage and direct traffic across multiple models and replicas.
- **LLM App-Tailored Autoscaler**: Dynamically scale inference resources based on real-time demand.
- **Unified AI Runtime**: A versatile sidecar enabling metric standardization, model downloading, and management.
- **Distributed Inference**: Scalable architecture to handle large workloads across multiple nodes.
- **Distributed KV Cache**: Enables high-capacity, cross-engine KV reuse.
- **Cost-efficient Heterogeneous Serving**: Enables mixed GPU inference to reduce costs with SLO guarantees.
- **GPU Hardware Failure Detection**: Proactive detection of GPU hardware issues.

## Quick Start

To get started with AIBrix, clone this repository and follow the setup instructions in the documentation. Our comprehensive guide will help you configure and deploy your first LLM infrastructure seamlessly.

```shell
# Local Testing
git clone https://github.com/vllm-project/aibrix.git
cd aibrix

# Install nightly aibrix dependencies
kubectl apply -k config/dependency --server-side

# Install nightly AIBrix CRDs (separate from the operator so uninstalls don't wipe user CRs)
kubectl apply -k config/crd --server-side

# Install nightly aibrix components
kubectl apply -k config/default
```

Install stable distribution
```shell
# Install component dependencies
kubectl apply -f "https://github.com/vllm-project/aibrix/releases/download/v0.7.0/aibrix-dependency-v0.7.0.yaml" --server-side

# Install AIBrix CRDs (separate from the operator so uninstalls don't wipe user CRs)
kubectl apply -f "https://github.com/vllm-project/aibrix/releases/download/v0.7.0/aibrix-core-crds-v0.7.0.yaml" --server-side

# Install aibrix components
kubectl apply -f "https://github.com/vllm-project/aibrix/releases/download/v0.7.0/aibrix-core-v0.7.0.yaml"
```
