One writer's experience with AI summarizers: "ChatGPT isn’t summarising at all, it only looks like it. What it does is something else and that something else only becomes summarising in very specific circumstances." (Depending on the text, the training sets, and parameters, the writer notes it condensing the text without regard to its most salient points, recycling others' summaries of the same or similar texts, or fabricating details when asked for more information.) https://ea.rna.nl/2024/05/27/when-chatgpt-summarises-it-actually-does-nothing-of-the-kind/
