The way you ask that question implies that an article summary is some kind of necessity. What happened to just... reading the article?
Most of the time, I don't want a summary of an article. If the article is really good and I want to know the most important details, then I should read the article. Maybe I can write a summary myself, so that I can use it for future reference.
If an article is bad, then why would I care about a summary? I wouldn't read it either way.
There is a a possibility that an article is actually really good, but it's badly written, or way too verbose, or I don't understand the language/terminology/topic. In these cases, a simpler summary written by someone else (or an LLM, I guess...) would be useful. Domain-specific articles or scientific papers would fall into this category for me. Even for this subset of articles, if I don't really understand the topic being discussed, would a summary really give me any benefits? I still don't understand the topic well enough for it to be useful to me. I would get more out of actually trying to read the article and studying the material being discussed.
