Am I missing something? Llama 2 is not Open Source.
Honestly, I'm not even sure that Open Source applies to an LLM, it seems like it would be better released under an Open database license? That assumes that copyright applies to LLM weights in the first place, which as far as I know has not been tested in a court.
But regardless, Llama 2 is not Libre, it's a proprietary license that happens to allow for commercial work. I'm not sure if the article is just conflating Open Source and source available (which again... doesn't actually seem all that applicable to model weights anyway), or if the article means something else entirely when it uses the term.
They are probably just repeating facebook's ridiculous claim that it is open source. The header of the release announcement is "The next generation of our
open source large language model"
