> Thanks to the open-source efforts like LLaMA ...

Is the LLaMA model really open source now? Last I checked it was only licensed for non-commercial use, which isn't open source software at least. Have they changed the license? Are people depending on "databases can't be copyrighted"? Are people just presuming they won't be caught?

There's lots of OSS that can use LLaMA but that's different from the model itself.

This is a genuine question, people are making assertions but I can't find evidence for the assertions.

Not all implementations of it use the same license. See for example lit-llama by Lightning AI:

That is for code to download the model, not for the model itself.

They actually reimplemented the code to load the model. But it’s not clear if the weights of the model are free to use or not

What do you mean, it's not clear?
