How to use Kimi K2.6 for free with Cloudflare Worker AI
Kimi K2.6 from Moonshot AI is the latest open source model that is on par with Opus 4.6 (Max) mode based on the benchmarks.
It is available in Cloudflare Worker AI which you can use it for free. Probably for your personal projects, the limit might be sufficient.
We’ll be using Cloudflare’s AI Gateway who takes care of the request/response transformation, etc so that we can just use it with any SDK like OpenAI’s SDK or Anthropic’s SDK.
Let’s first create a new AI gateway
Make sure to configure the auth. You can turn on logging, caching, rate limiting based on your needs :)
In the code samples select “Unified API” and “Worker AI”
And here you go. Just replace the $CF_AIG_TOKEN token with the token that you’ve created.
Now you should be able to access any models that is available in Cloudflare Workers AI.
curl -X POST https://gateway.ai.cloudflare.com/v1/$CF_ACCOUNT_ID/nesin-ai/compat/chat/completions \

And their dashboard to view the logs and other metrics is so clean as well.
