More concretely, an ML mode is only "open source" if both the training code and the training data are freely available.
Otherwise, it's not possible for the community to reproduce the model.

Everything that has a source, has another source that has produced that source.
The algorithms behind creating LLMs are all published papers for all to read, the libraries (like TensorFlow) are themselves FOSS projects, and the data... is the open web for the most part.
The Wikipedia dump alone is more than enough to get a very decent LLM shaped up.
How an LLM is produced IS NO SECRET. It's just that to produce it you need millions (or for the more sophisticated ones: billions) in data center fees / power / GPU to train the model. So if the training scripts were included, you still can't make a LLama model yourself at home.
Wait, what? You can build the FOSS app entirely from the source. You don’t need a copy of the programmer.
(edit to spell Llama correctly)
The currently LLM status is more akin to opensource plugins to some propriety system, like game modding.
The model weights can't be scrutinized? Well no one can scrutinize them. Even those who made the model.
And because you don't have the hardware to reproduce Llama anyway, even if they gave you the code to build it, you can't verify they used that code to build it. And if you have the hardware and data, you probably still wouldn't spend MILLIONS to end up... with the same exact model they gave you in the first place.
Do you understand how meaningless this entire "Llama is not truly open" bullshit is?
No you wouldn't end up with the exact same model weights if you trained it yourself on the same data but you could compare how the models perform when given the same prompts and to try to identify anomalous variation that could point you towards Facebook misrepresenting us about what went into the training / fine-tuning.
Do I need to keep going so you see how stupid the discussion is?
You think like a software developer. Everything is just buncha text, a compiler and build environment. That's not like that.
There's too much shit going in, and the rights of the data are absolutely not clear. But if they had to be, the model wouldn't exist. What you want it friggin' impossible.
