This is like saying any python program is open source because the python runtime is open source.

Inference code is the runtime; the code that runs the model. Not the model itself.

I disagree. The file I linked to, model.py, contains the Llama 3 model itself.

You can use that model with open data to train it from scratch yourself. Or you can load Meta’s open weights and have a working LLM.

Yeah a lot of people here seem to not understand that PyTorch really does make model definitions that simple, and that has everything you need to resume back-propagation. Not to mention PyTorch itself being open-sourced by Meta.

That said the LLama-license doesn't meet strict definitions of OS, and I bet they have internal tooling for datacenter-scale training that's not represented here.

That makes it source available ( https://en.wikipedia.org/wiki/Source-available_software ), not open source
