The code I linked is the model source -- the structural skeleton. You can create a model with this source and put whatever weights you want in it -- just like Doom.
No that's what I was getting at. For roughly half the models I come across, the weights are published on HF. For the other half, the weights are available via GitHub (either the releases section, or a link to something like Google Drive).
It is definitely possible. At any point, you can just take a snapshot of the weights. Together with a description of the architecture, this is a complete description of a model.
