it is that they didn’t pay for the books they read, like people are supposed to do legally.
If I can read a book from a library, why shouldn't OpenAI or anybody else?
...but yes from what I've heard they (or whoever, don't remember) actually trained on libgen. OpenAI can be scummy without the general process of feeding AI books you only have read access to being scummy.
They don't keep copies and learning speed? Why one day? Does it count if I skim through a book?
