alt Hacker NewsMy experience with ChatGPT as a search engine - it is totally paranoid about checking and re-checking its answers by referencing them in multiple places (I usually read its thinking output). I have not seen an outright hallucination for at least a year. (It is of course a different situation with Google's "AI summary" which is wrong half of the time.)
Ironically I quit using ChatGPT a while back. I decided to run it through it's paces and asked it some rather detailed questions about a range of topics that I have significant domain knowledge on. Without exception the responses I got back where glibly superficial to the point the responses were almost totally devoid of meaningful information. The AI summary on Google search results is so bad it represents an assault on reason.
