# Gradient AI

Fine-tuning and inference platform for open-weight models.

**LiteLLM prefix:** `gradient_ai/`  
**Status:** Stub — routes through OpenAI-compatible client  
**Docs:** https://docs.gradient.ai

## Authentication

| Variable | Required | Description |
|---|---|---|
| `GRADIENT_ACCESS_TOKEN` | Yes | Access token from gradient.ai |

## Quick Start

### Single-Backend (env vars)

```bash
BACKEND=gradient_ai GRADIENT_ACCESS_TOKEN=your-token cargo run -p anyllm_proxy
# Docker:
docker run -e BACKEND=gradient_ai -e GRADIENT_ACCESS_TOKEN=your-token -e PROXY_OPEN_RELAY=true -p 3000:3000 followthewhit3rabbit/anyllm-proxy
```

### LiteLLM YAML Config

```yaml
model_list:
  - model_name: llama3-gradient
    litellm_params:
      model: gradient_ai/llama3-8b-instruct
      api_key: "env:GRADIENT_ACCESS_TOKEN"
```

## Usage Examples
