If people are on the fence on whether a given AI model use data or object code, then lets just use real example AI-programs and put it through the rigor of real GPLv3 style compliance on real programs.
I did this with my own projects (which now feel ancient being over 20 years old) and this convinced me beyond a doubt that training data needs to be provided to comply with the letter of the GPL. It is robot controller based on an AI model. Corresponding source includes training data.
