Not sure why the FSF or any other organization hasn't released a license like this years ago already.

Because it would violate freedom zero. Adding such terms to the GNU GPL would also mean that you can remove them, they would be considered "further restrictions" and can be removed (see section 7 of the GNU GPL version 3).

Freedom 0 is not violated. GPL includes restrictions for how you can use the software, yet it's still open source.

You can do whatever you want with the software, BUT you must do a few things. For GPL it's keeping the license, distributing the source, etc. Why can't we have a different license with the same kind of restrictions, but also "Models trained on this licensed work must be open source".

Edit: Plus the license would not be "GPL+restriction" but a new license altogether, which includes the requirements for models to be open.

That is not really correct, the GNU GPL doesn't have any terms whatsoever on how you can use, or modify the program to do things. You're free to make a GNU GPL program do anything (i.e., use).

I suggest a careful reading of the GNU GPL, or the definition of Free Software, where this is carefully explained.

> You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:

"A work based on the program" can be defined to include AI models (just define it, it's your contract). "All of these conditions" can include conveying the AI model in an open source license.

I'm not restricting your ability to use the program/code to train an AI. I'm imposing conditions (the same as the GPL does for code) onto the AI model that is derivative of the licensed code.

Edit: I know it may not be the best section (the one after regarding non-source forms could be better) but in spirit, it's exactly the same imo as GPL forcing you to keep the GPL license on the work

I think maybe you're mixing up distribution and running a program, at least taking your initial comment into account, "if you train/run/use a model, it must be open source".

I should have been more precise: "If you train and distribute an AI model on this work, it must use the same license as the work".

Using AGPL as the base instead of GPL (where network access is distribution), any user of the software will have the rights to the source code of the AI model and weights.

My goal is not to impose more restrictions to the AI maker, but to guarantee rights to the user of software that was trained on my open source code.
