Llama 2 is open source-ish. Weights are freely available and can be commercially used, but only if you have less than 700m users and agree to some "don't do naughty things" terms.

There are other LLMs that don't have such restrictions, and publish their training data.
Edit: this is in fact fairly interesting discussion because LLM is a new breed of digital products. Meta's terms are practical for limiting the usage for commercial applications, and they are designed to protect the general population. It's not the worn out "protecting us from ourselves", its actually preventing Llama users from harming non-users. Yes, we can be jaded and say it's about protecting the brand and dissociating from bad actors. My point is that it's hard to apply usual arguments for open source and freedom of computing, when you're defending rights of people who want to harm other people.
Also "don't do naughty things", is there a chart for that? How is that defined, is it part of the non-existing license?
