Kilo Gateway

Kilo Gateway provides a unified API that routes requests to many models behind a single endpoint and API key. It is OpenAI-compatible, so most OpenAI SDKs work by switching the base URL.

​
Getting an API key

  1. Go to app.kilo.ai
  2. Sign in or create an account
  3. Navigate to API Keys and generate a new key

​
CLI setup

pllan onboard --kilocode-api-key <key>
Or set the environment variable: 
export KILOCODE_API_KEY="<your-kilocode-api-key>" # pragma: allowlist secret

​
Config snippet

{
  env: { KILOCODE_API_KEY: "<your-kilocode-api-key>" }, // pragma: allowlist secret
  agents: {
    defaults: {
      model: { primary: "kilocode/kilo/auto" },
    },
  },
}

​
Default model

The default model is kilocode/kilo/auto, a smart routing model that automatically selects the best underlying model based on the task:
  • Planning, debugging, and orchestration tasks route to Claude Opus
  • Code writing and exploration tasks route to Claude Sonnet

​
Available models

Pllan dynamically discovers available models from the Kilo Gateway at startup. Use /models kilocode to see the full list of models available with your account. Any model available on the gateway can be used with the kilocode/ prefix: 
kilocode/kilo/auto              (default - smart routing)
kilocode/anthropic/claude-sonnet-4
kilocode/openai/gpt-5.2
kilocode/google/gemini-3-pro-preview
...and many more

​
Notes

  • Model refs are kilocode/<model-id> (e.g., kilocode/anthropic/claude-sonnet-4).
  • Default model: kilocode/kilo/auto
  • Base URL: https://api.kilo.ai/api/gateway/
  • For more model/provider options, see /concepts/model-providers.
  • Kilo Gateway uses a Bearer token with your API key under the hood.
