## Self-hosted AI

By default, AI features in Forest Admin are processed by Forest Admin servers. To keep your data private, you can route AI requests through your own agent using the `addAi` method—your data never leaves your infrastructure.

### Installation

```bash
npm install @forestadmin/ai-proxy
```

### Configuration

{% tabs %}
{% tab title="OpenAI" %}

```javascript
import { createAiProvider } from '@forestadmin/ai-proxy';

const agent = createAgent(options)
  .addDataSource(/* ... */)
  .addAi(
    createAiProvider({
      name: 'my-assistant',
      provider: 'openai',
      apiKey: process.env.OPENAI_API_KEY,
      model: 'gpt-4o',
    }),
  );
```

{% endtab %}

{% tab title="Anthropic" %}

```javascript
import { createAiProvider } from '@forestadmin/ai-proxy';

const agent = createAgent(options)
  .addDataSource(/* ... */)
  .addAi(
    createAiProvider({
      name: 'my-assistant',
      provider: 'anthropic',
      apiKey: process.env.ANTHROPIC_API_KEY,
      model: 'claude-sonnet-4-5',
    }),
  );
```

{% endtab %}
{% endtabs %}

### Supported models

Any model with function/tool calling support works. See the [full list of unsupported models](https://github.com/ForestAdmin/agent-nodejs/blob/main/packages/ai-proxy/src/supported-models.ts) for details.
