# Self-hosted AI

{% hint style="success" %}
This is the official documentation of the `@forestadmin/agent` Node.js agent.

## 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 %}

### Options

| Option     | Type                        | Required | Description                                                           |
| ---------- | --------------------------- | -------- | --------------------------------------------------------------------- |
| `name`     | `string`                    | Yes      | Unique identifier for this AI configuration                           |
| `provider` | `'openai'` \| `'anthropic'` | Yes      | AI provider                                                           |
| `model`    | `string`                    | Yes      | Model to use (see supported models below)                             |
| `apiKey`   | `string`                    | No       | API key (defaults to `OPENAI_API_KEY` or `ANTHROPIC_API_KEY` env var) |

All provider-specific options are also supported: [ChatOpenAI options](https://docs.langchain.com/oss/javascript/integrations/chat/openai) (`configuration`, `temperature`, `maxTokens`, etc.) and [ChatAnthropic options](https://docs.langchain.com/oss/javascript/integrations/chat/anthropic) (`anthropicApiUrl`, `temperature`, `maxTokens`, `topK`, etc.).

### 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.
