SQLsaber supports multiple LLM providers.

### Providers

SQLsaber supports the following LLM providers:

- **Anthropic** - API key
- **OpenAI** - API key
- **Google** - API key
- **Groq** - API key
- **Mistral** - API key
- **Cohere** - API key
- **Hugging Face** - API key

<Aside type="note">
  SQLsaber stores API keys securely using your operating system's credentials
  store.
</Aside>

### Quick Setup

The fastest way to configure authentication:

```bash
saber auth setup
```

This interactive command will:

1. Let you choose your AI provider
2. Prompt you for an API key (or use an existing environment variable)
3. Securely store your credentials

#### Anthropic

SQLsaber uses Claude Opus 4.6 by default.

##### API Key

1. Get an API key from [Anthropic Console](https://console.anthropic.com/)
2. Run the setup:
   ```bash
   saber auth setup
   ```
3. Choose "Anthropic" as your provider
4. Enter your API key when prompted

<Aside type="note">Follow the same steps for setting up other providers.</Aside>

### Managing Authentication

#### Check Authentication Status

See which providers are configured:

```bash
saber auth status
```

This shows:

- Configured providers
- Whether a provider is configured via environment variable or keychain

#### Reset Authentication

To remove stored credentials for a provider:

```bash
saber auth reset
```

This will:

1. Ask you to select which provider to reset
2. Remove the stored API key from your OS credentials store

### Multiple Providers

You can configure multiple providers and switch between them when selecting models. Each provider's credentials are stored securely and independently.

### Environment Variables

You can also use environment variables for setting API keys.

Example:

```bash
# Anthropic
export ANTHROPIC_API_KEY="your-api-key"

# OpenAI
export OPENAI_API_KEY="your-api-key"

# Google
export GOOGLE_API_KEY="your-api-key"
```

Environment variables take precedence over stored credentials.

### Getting Help

Check authentication status and configuration:
