# Lambda AI

GPU cloud provider offering inference for large open-source models at competitive rates.

**LiteLLM prefix:** `lambda_ai/`  
**Status:** Stub — routes through OpenAI-compatible client  
**Docs:** https://lambda.ai/api-documentation

## Authentication

| Variable | Required | Description |
|---|---|---|
| `LAMBDA_API_KEY` | Yes | API key from cloud.lambda.ai |

## Quick Start

### Single-Backend (env vars)

```bash
BACKEND=lambda_ai LAMBDA_API_KEY=your-key cargo run -p anyllm_proxy
# Docker:
docker run -e BACKEND=lambda_ai -e LAMBDA_API_KEY=your-key -e PROXY_OPEN_RELAY=true -p 3000:3000 followthewhit3rabbit/anyllm-proxy
```

### LiteLLM YAML Config

```yaml
model_list:
  - model_name: llama3.1-405b
    litellm_params:
      model: lambda_ai/llama3.1-405b-instruct-fp8
      api_key: "env:LAMBDA_API_KEY"
```

## Usage Examples
