Interestingly your comment is the very opposite of my experience with LLMs.
You can rely on them for creative stuff (write a poem, short story, etc.), but you cannot depend on them for factual stuff. Time and time again they will state "facts" that turn out to be false, and so now I no longer trust it for anything without manual verification. And since I then need to do the research myself for the verification, I rarely find LLMs helpful, except occasionally for initial exploration of some topic.
I revisit LLMs a couple of times a year to see if they have gotten any better and it's not a great experience, but I will admit they have gotten slightly better. Still lack and will lack ability to understand what they are processing.

You used summarization as an example, but whether they are fundamentally good at that is even debatable, e.g. https://ea.rna.nl/2024/05/27/when-chatgpt-summarises-it-actu...
