Connecting an AI Provider

Kilo Code requires an API key from an AI model provider to function.

We recommend these options for accessing the powerful Claude 4 Sonnet model:

• Kilo Code API provider (Recommended): Provides access to all of the models available through OpenRouter with competitive pricing and free credits to get started. View pricing
• OpenRouter: Provides access to multiple AI models through a single API key. View pricing.
• Anthropic: Direct access to Claude models. Requires API access approval and may have rate limits depending on your tier. See Anthropic's pricing page for details.

Using the Kilo Code Provider

By default when you install Kilo Code the extension, you'll be prompted to sign in or create an account in the Kilo Code Provider.

That will walk you through the account setup and automatically configure Kilo Code properly to get you started. If you'd rather use another provider, you'll need to manually get your API key as described below.
