Curious to know why this is the case? I haven't played around with LLAMA yet but I figured it being open-source would make it more trustworthy than models provided by OpenAI.
Absolutely not. The LLAMA license [1] is clear that it's not open source. It's for non-commercial, research only, and only by explicit permission from Meta. The weights were leaked, on 4chan [2], illegally, according to the license. Very very few people are using it legally. This interpretation is clear from its wording, and also matches the interpretation of our flock of lawyers.

But, Llama 2 is not open source [1].
