I tried TLDR on a CNN article and it failed saying that it was from the future - perhaps because the URL itself contained a 2023 date.
Separately, are you using Bing's crawl of the net as opposed to doing a direct web request to get that data?
Another interesting thing noted by a YouTuber was that if you ask ChatGPT to summarize an article, the article does not end up in context.
Like, if you have it summarize a page with code on it, it won't be able to reference the code that was on that page when doing things.
Of course, I would not be shocked if the TLDR feature was using the 2021 database. In which case its response is fine.
