It's not open source it's weight available(for now). As of now there's nothing you can do with it publicly because it lacks a license and is known to be stolen.
Definitely. It has some alignment, but it won’t straight up refuse to do anything. It will sometimes add notes saying that what you’ve asked is kinda maybe against the law, but will produce a great response regardless.
It’s a 70b, so running it locally is kind of a challenge, but for those who can run it - there is simply no other LLM that you can run at home that gets even close to it.
It follows instructions amazingly, it’s very consistent and barely hallucinates. There is some special mistral sauce in it for sure, even if it’s “just” a llama2-70b.
I’ve no idea what happened in this case. But it is extremely common for companies to take closed source developments and transform them into open source after they go through an internal process.
