Found a cool service - Kaggle . Gives 30 free GPU hours per week. And I had this idea: what if I run Qwen3-8B there and expose it through an API on Cloudflare Workers?

Honestly not sure what this is useful for. Just wanted to know if I could pull it off.

Planned to finish in a couple of hours. Finished over the weekend.

So Why Bother?

As I was figuring things out, I realized this could work as a free replacement for a paid AI API - for example in R-Searcher , my Chrome extension for reading articles. Or just as a personal AI backend with no subscription and no token limits.

But honestly - the idea came first, the reason came later. Not the other way around.

So the task: a client sends a request, Qwen on Kaggle processes it, the response comes back. For free. The first problem showed up five minutes in.

The Problem: Kaggle Has No Inbound Traffic

Kaggle is a Jupyter notebook on a cloud GPU. No public IP. No incoming connections.…
