> Studies have found ethanol levels in commercial apple juice ranging from 0.06 to 0.66 grams per liter, with an average around 0.26 grams per liter[1]
Even apple juice is an alcoholic drink if you push your criteria to absurdity.
The "source" for something is all the stuff that makes you able to build and change that something. The source for a model is all the stuff that makes you able to train and change the model.
Just because the model produces stuff doesn't mean that's the model's source, just like the binary for a compiler isn't the compiler's source.
