Use cases
When you want to summarize something, clearly!
An excellent other use case is sending context to tools like ChatGPT to get answers from. These tools have limited amounts of text they can read, so you can’t say “here’s a whole book, do my homework.” What you can do is summarize each chapter of the book, send it to ChatGPT and say “here are the chapter summaries, do my homework” (or maybe, “what chapter do I need to read?” and then send it that chapter).

State of the art
There are so many aspects to text summarization!
Although from selecting GigaWord at random, Pegasus and BART seem to be pretty good options.
