Certain Mathematical models seem to work well. And I've heard that some decent programmers like to use it to get together code they would have spent hours on GitHub looking for to copy and paste.

And if it wasn't so wasteful, I like the idea of using generative AI for getting visuals for (PRIVATE) TTRPGs. When I just want my group to have a better understanding of what my BBG, "Lord Gargle Deeznuts" looks like. And that's only if I can generate something decent for free. If I have to pay, it would be better to pay a real human to do the labor.

Other than than those very specific cases, I really don't believe there is any commercial use for current LLM. Everything is so completely unethical IMO, that even the grey area of generative AI that I mentioned above immediately become unethical the moment a human profits off it.
