> are all open models still just derivatives of llama?
No there are several others but by far the best alongside llama are Mistral’s mistral and mixtral models. Those are called the foundation models which everyone else builds on top of
Mistral is not “open source” either since we cannot reproduce it (the training data is not published). Both are open weight models, and they are both released under a license whose legal basis is unclear: it's not actually clear if they own any intellectual property over the model at all. Of course they claim such IP, but no court has ruled on this yet AFAIK and legislators could also enact laws that make these public domain altogether.
