The Doom executable is open source. The data is not. Explicitly, the data is under a different license than the GPL and makes no claims about being open source. There are total conversion mods that replace the closed source levels with open source ones however.

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.
If you create a model with this code and save it to disk, it will indeed be 14GB.
It will be random weights -- the contents won't be there -- but it will be 14GB.
If you use only what is open-source about Doom, you will have an unplayable game.
If you use only what is open-source about Mistral, you will have an ineffective model.

Here's the source the engineers that created doom used to build the doom engine: https://github.com/id-Software/DOOM
Where is the source used to build this model?
