I haven't had this from ChatGPT and haven't used paid ChatGPT to test GPT 4.0 there, but with Bing (Creative) specifically I've had it regularly tell me it doesn't know something. It still hallucinates other things, but it's no longer just a lying yes man. If you ask it for information it can't find or a task it can't do, there's a very good chance it says "Sorry, I can't do that." The other day I was trying to find out what percentage of Konstantin Tsiolkovsky's works were published before the age of 60 vs after the age of 60, something that's almost impossible to find on the internet (I don't speak Russian). I spent a lot of time trying to get Bing to answer it for me (didn't succeed), and one of the times I asked it to look up all the bibliographic information it could on Tsiolkovsky, go through each file and count the dates of publication, then tell me how many were after his 60th year. It said "Sorry, that would require me to download and analyse a large number of PDFs, which is outside my current capabilities. I'm sorry I couldn't be of more assistance this time. " They've improved a lot on the Yes Man aspect of it.
