Use a Kimi-Compatible API with an Unofficial Cowork-Style Fork

This guide covers a third-party, Cowork-style project originally demonstrated by developer @austinit. It is not Claude Cowork, is not supported by Anthropic, and may no longer match the original distribution. Verify the project source, license, recent activity, and security model before installing anything.

This guide walks you through setting up a forked version of Claude Cowork that works with any Anthropic-compatible API—including Kimi K2, MiniMax, and other third-party providers.

The Problem: Claude Cowork's Limitations

Claude Cowork is an incredible AI collaboration tool, but it comes with some restrictions:

Limitation	Impact
Separate product and account	Official Cowork is included with paid Claude plans; an unofficial fork uses its own provider and setup
No third-party APIs	Cannot use alternative Anthropic-compatible providers

For users who want to use third-party APIs or access models from other providers (like Kimi K2), this is a significant limitation.

The Solution: Austin's Open-Source Fork

Developer @austinit spent half a day building an open-source fork of Claude Cowork that allows you to use any Anthropic-compatible API.

Project Availability

CoworkHow no longer publishes GitHub repository links from this site. If you are evaluating this path, use the project's current distribution channel or your own internal copy.

The original demo showed the fork organizing files with a third-party model. Treat that as a historical demonstration, not proof that the current package is maintained or safe.

Setup Guide: 15 Minutes to Get Started

Step 1: Get the Project Files

Start from the fork's current distribution package or an internal project copy, then open the project folder locally.

Step 2: Open with Antigravity

This is the magical part of the setup process. When you open the project with Antigravity (Google's AI coding assistant), you can simply tell it: "I want to use Kimi's API" and it will automatically open the settings interface for you!

Step 3: Configure Your API

Reference the Kimi official documentation for configuration:

Configuration Guide: platform.moonshot.ai/docs/guide/agent-support

Kimi official configuration documentation

Fill in the following information according to the documentation:

API Key - Your Kimi API key from the Moonshot platform
API Endpoint - https://api.moonshot.cn/anthropic
Model Selection - Options include:
- kimi-k2 (standard)
- kimi-k2-turbo-preview (faster, 60-100 tokens/s)
- kimi-k2-thinking (256K context, multi-step reasoning)

Example Configuration

Your settings.json should look something like this:

{
  "alwaysThinkingEnabled": false,
  "env": {
    "ANTHROPIC_AUTH_TOKEN": "sk-your-kimi-api-key-here",
    "ANTHROPIC_BASE_URL": "https://api.moonshot.cn/anthropic",
    "ANTHROPIC_MODEL": "kimi-k2-turbo-preview"
  }
}

That's it! Configuration complete—you're ready to use Cowork with Kimi K2!

Real Results: Impressive Performance

After configuration, I asked it to help organize my desktop files. The results were amazing!

Look at that organized desktop—completely clean! All files were intelligently categorized and sorted. No more messy desktop chaos!

Cost Advantage: Incredible Value

As the community has noted:

"CTO is Claude Code, COO is Claude Cowork—and it only costs $200/month. That's cheaper than a full-time intern!"

This cost advantage is remarkable. Whether you're an individual developer or a small team, this is completely affordable.

Kimi K2 Pricing Reference

Model	Context	Best For
kimi-k2	Standard	General tasks
kimi-k2-turbo-preview	Standard	Fast responses (60-100 tok/s)
kimi-k2-thinking	256K	Complex reasoning tasks
kimi-k2-0905-preview	256K	Enhanced coding capability

Summary

This experience has been fantastic! Thanks to @austinit for developing this open-source project. Here's what you get:

✅ Use any Anthropic-compatible API (Kimi K2, MiniMax, etc.)
✅ Enjoy Claude Cowork's powerful features (file management, organization, automation)
✅ Super simple setup (15 minutes to get running!)
✅ Cost-effective (pay only for API usage)

If you want to experience Claude Cowork but don't want to be limited to the official API, strongly recommend trying this open-source version!
