A model isn't an application. It doesn't have source code. Any more than an image or a movie has source code to be "open". That's why OSI's definition of an "open source" model is controversial in itself.

It's clear you're being disingenuous. A model is its dataset and its weights too but the weights are also open and if the source code was as irrelevant as you say it is, Deepseek wouldn't be this much more performant, and "Open" AI would have published it instead of closing the whole release.
