All you have to do is present credible evidence that these companies are distributing copyrighted works or a direct substitute for those copyrighted works. They have filters to specifically exclude matches though, so it doesn’t really happen.

It’s like stealing from shops except the shops didn’t lose anything. You’re up a stolen widget, but they have just as many as before.

Detecting a hallucination programmatically is the hard part. What is truth? Given an arbitrary sentence, how does one accurately measure the truthfulness of it? What about the edge cases, like a statement that is itself true but misrepresents something? Or what if a statement is correct in a specific context, but generally incorrect?

I’m an AI optimist but I don’t see hallucinations being solved completely as long as LLMs are statistical models of languages, but we’ll probably have a set of heuristics and techniques that can catch 90% of them.
