Bring Your Own Key (BYOK)
Bring Your Own Key (BYOK) lets you use your own API keys when using the Kilo Gateway, while retaining Kilo platform features like Code Reviews and Cloud Agents.

- Utilize new models quickly, Kilo Gateway supports most new models in minutes
- Use subscriptions with third-party AI providers, for example Z.AI or Minimax
- Attribute usage against existing provider commitments or agreements
- Use existing credits with a provider

How Bring Your Own Key works
- When you use the Kilo Gateway provider, Kilo checks if there’s a BYOK key for the selected model’s provider.
- If a matching BYOK key exists, the request is routed using your key.
- If the key is invalid, the request fails. It does not fall back to using Kilo's keys.
Using BYOK in the Extensions and CLI
- BYOK works with the Kilo Gateway provider. Users should ensure that is set as the active provider.
- Select a model from a provider configured for BYOK, for example Claude Sonnet 4.5 if you configured BYOK for Anthropic.
- (Optional) Validate with the provider that traffic is being served by that key.
Limitations
- BYOK is not fully supported by Agent Manager. See Agent Manager for details.
