Earlier quoted context omitted.
> Alpaca is cool but it's also not technically allowed by OpenAI's TOS, and LLaMA is certainly not allowed to be used for non-commercial purposes. Only if you agreed to the ToS or believe that the weights are copyrightable (precedents set by the copyright office and the courts strongly suggest that they aren't). I personally see no issue in using these models for commercial purposes.
You might not but a company will think twice. It's the same reason why companies could theoretically use pirated Windows and Adobe products and get away with it, but most don't because the risk is not worth the reward.
Again, using and distributing LLaMA weights is not illegal in any way under current laws. End of story.
