pi-provider-kimi-code

A pi-coding-agent custom provider extension that adds Kimi Code models with OAuth device-code login.

Install

pi install npm:pi-provider-kimi-code

Or load without installing:

pi -e /path/to/pi-provider-kimi-code

Authentication

OAuth (recommended)

Inside pi, run:

/login kimi-coding

This starts the device-code flow — a browser window opens, you authorize, and credentials are stored automatically.

API Key

Set the KIMI_API_KEY environment variable:

KIMI_API_KEY=sk-... pi

Models

| ID | Name | Reasoning | Input | Context | Max Output | |---------------------------|--------------------------------|-----------|-------------|----------|------------| | kimi-code | Kimi Code (powered by kimi-k2.5) | yes | text, image | 262 144 | 32 768 | | kimi-k2.5 | Kimi K2.5 | yes | text, image | 262 144 | 32 768 | | kimi-k2-thinking-turbo | Kimi K2 Thinking Turbo | yes | text | 262 144 | 32 768 |

Select a model inside pi:

/model kimi-coding/kimi-code

Environment Overrides

• KIMI_CODE_BASE_URL — override the default API base URL (https://api.kimi.com/coding)
• KIMI_CODE_OAUTH_HOST — override the OAuth host
• KIMI_OAUTH_HOST — fallback OAuth host override for compatibility

How It Works

• Registers provider kimi-coding with base URL https://api.kimi.com/coding
• Uses api: "anthropic-messages" — Kimi's API is wire-compatible with the Anthropic Messages format
• Adds a small streamSimple wrapper to suppress Kimi's leaked (Empty response: ...) placeholder blocks
• Sends the same KimiCLI/1.28.0 + X-Msh-* headers as current kimi-cli
• Persists a stable device ID at ~/.pi/providers/kimi-coding/device_id
• OAuth uses RFC 8628 device authorization grant against https://auth.kimi.com
• Zero dependencies — types from @mariozechner/pi-ai and @mariozechner/pi-coding-agent are provided by the pi runtime
• Zero build step — pi loads TypeScript directly via jiti

This extension is based on the OAuth implementation from kimi-cli by Moonshot AI.
