With later models (e.g. GPT 4o and GPT 5) it still happens but not as much. Not only that, but if you are using the bot properly, such hallucinations are instantly detectable. If anyone is ever fooled into believing something based on a chatbot hallucination, it is proof possitive that they were using the bot for purposes it was not designed for.
In a thread that has apparently been deleted, you told Lon goodbye forever and that you were done with TOL so I'm not going to spend much time replying to your post except to say that for anyone reading your above, I'd recommend they look for themselves into how chatbots hallucinate, and why and what that means for factual accuracy.
And for the love of Pete, already I wish people would stop relying on chatbots to do their thinking for them. I've seen too many forum members here and elsewhere give some variation on "I sent your post through chat GPT to understand/respond to it" and then insert their own biases into the prompt ensuring them AI would give a summation that would confirm their negative opinion of the other poster and justify their own response.
Now it's "I asked chatGPT this" and "I had this conversation with chatGPT" and now people are relying on chatGPT for things in all kinds of categories for which they used to use their own brain. And no, it's not like using a calculator instead of a pencil or doing a Google search, people are literally and mindlessly allowing chatGPT to do the heavy lifting of the simplest things, including trying to understand what someone has just said to them.
When I see someone say "I used/asked/prompted chatGPT" to compose a post, I've begun ignoring those posts. Bullet points? Several key categorical headings, followed by a conclusion? Dead giveaways, even if they don't say they used it upfront, which at least you have done, but not everyone does. Forums seem like a last vestige of the old internet, but if users are mostly chatGPT regurgitators then why bother?
Sorry
@chrysostom for my part in taking your thread off-topic.
Edited to add: The thread is back, I guess maybe it was temporarily hidden.
