Which matters because training an LLM very likely is not protected by copyright.

While for a copyrighted work the default is that you can’t use it unless you have a valid license, for an LLM the default is that you can use it unless you have signed a contract restricting what you can do in return for some consideration.

I don’t think these contracts are designed to be enforced because an attempt to enforce it would reveal it to be hot air, they are just there to scare people into compliance.

Better to download LLMs from unofficial sources to avoid attempted contract shenanigans.
