Same 3 is the only use case I've found that works well enough. But I'll still usually take a look on google / reddit / stackoverflow / books first just because the information is more reliable.

But it's usually an iterative process, I find pattern A and B on google, I'll ask the LLM and it gives A, B and C. I'll google a bit more about C. Find out C isn't real. Go back and try other people commenting on it on reddit, go back to the LLM to sniff out BS, so on and so on.
