What if you reword it as copyleft-AI GPL.
You may only use this code to train “open” models, that are themselves subject to the copyleft-AI GPL.
In that case you would just spell out, that you consider the model a derivate of your work.
Most likely yes, because it imposes additional conditions about the use of the code.
It’s also either incompatible with MIT or easily worked around.
It's an open source license, but not an Open Source one.
