Open weights, not open source.
The weights have permissive licensing, but the data and training pipeline are not published to reproduce them from their proprietary Qwen starting points. Weights are not "source."
Came directly to comments hoping not to see this one.

Surely someone will soon do what the title of this post makes it seem like cloudfare did. Truly modular open source training and inference logic, along with a totally open corpus and weights, will eventually out-compete the closed ecosystem.
Ok, we've put weights instead of source in the title, at least until someone comes along and says that's not right either!
