I use LLMs a lot, but I think the killer app is learning stuff fast. I am hoping LLMs make it possible to do much more creative research as a result.

ChatGPT O3 one-shots or few-shots hard assignments for upper-level CS classes. Compilers, web browsers, these are custom assignments, I've tested and don't think it's recall. The solutions are what I expect. It is like a very strong undergrad.
