Kilo Gateway OAuth Plugin for OpenCode

This plugin adds OAuth device login for the kilo provider in OpenCode.

Warning

The OAuth in this plugin may violate Kilo's TOS or future product restrictions. Use it at your own risk. Using the kilo provider doesn't violate TOS, since you did not agree to it.

Without the plugin

If you only want free models, configure the provider and stop there:

{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "kilo": {
      "name": "Kilo Gateway",
      "npm": "@ai-sdk/openai-compatible",
      "api": "https://api.kilo.ai/api/openrouter"
    }
  }
}

Free models where the alpha period has not yet ended as of March 12, 2026:

Lab	Model
MiniMax	MiniMax M2.5 (free)
StepFun	Step 3.5 Flash (free)
Arcee AI	Trinity Large Preview (free)

With the plugin

If you want to use the models requiring sign in, add the plugin and keep the same provider config:

{
  "$schema": "https://opencode.ai/config.json",
  "plugin": [
    "opencode-kilo-gateway@latest"
  ],
  "provider": {
    "kilo": {
      "name": "Kilo Gateway",
      "npm": "@ai-sdk/openai-compatible",
      "api": "https://api.kilo.ai/api/openrouter"
    }
  }
}

Login

Run:

opencode auth login

Then choose:

• Kilo Gateway

You should get the same device flow shape as Kilo CLI:

• browser opens to Kilo device auth
• code is shown in the terminal
• OpenCode waits for authorization

Which models appear is controlled by the configured kilo provider and the gateway.

Dev

Build the plugin locally:

npm install
npm run build

Install it into your OpenCode config directory:

cd C:\Users\User\.config\opencode
npm install "C:\Users\User\source\repos\plugin\opencode-kilo-gateway"

Then point opencode.json at the built file:

{
  "plugin": [
    "file:///C:/Users/User/.config/opencode/node_modules/opencode-kilo-gateway/dist/index.js"
  ]
}

When you change the plugin locally, rebuild it before testing:

npm run build

Note

How is this different from other Kilo plugins?

• this one knows Kilo provider setup already populates models, so you do not need it for free models
• it provides a working OAuth device login
• you do not need to choose Other
• it is based directly on Kilo CLI gateway auth code
