Authentication

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

Quick Setup

The fastest way to configure authentication:

saber auth setup

This interactive command will:

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

Anthropic

SQLsaber uses Claude Sonnet 4 by default.

API Key

Get an API key from Anthropic Console
Run the setup:
Terminal window
```
saber auth setup
```
Choose “Anthropic” as your provider
Enter your API key when prompted

Managing Authentication

Check Authentication Status

See which providers are configured:

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:

saber auth reset

This will:

Ask you to select which provider to reset
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:

# 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.
