A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.
Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

I've found it making up "facts" when I query it. I thought I was doing something wrong, but apparently, it's just changing the way it works for some reason.
Same. Now I'm only using search engines that don't have it.
It's not changing the way it works. It's making up shit when it doesn't know.
And that's how AI works, it's all probability. It's not answering 2+2, there's a probability that the answer is 4 and it chooses that. If something convinces it that it should be 5 it'll start answering 5
That's how language models work. It's grouped into AI as is so many things, but it's not AGI. It could open the doors to AGI as a component, but isn't actually thinking about its answers. And those probabilities are driven by training reinforcement which includes the bias of giving an answer the human will receive well. Of course it's going to "lie" or make up things if that improves the acceptance of the answer given.
The best description I've heard to give to most people is that llms knows what the right answer looks like, not what it is.
If I wanted that I could just ask my daughter. She makes up shit all the time when she doesn’t actually know.
Would probably be more fun that way too.
Expect it's Dog, not Snake. Bing thinks it's Ox. How did the entire field of AI go from surprisingly accurate to utterly useless in the span of under a year? I have no idea what benefits you personally see in this site.
How have you used Perplexity.ai?
Thanks for this reply. That's probably the best way to use LLMs - general definitions or framing / summarizing of issues. And then always check the sources to make sure it was accurate. I've played around with ChatGPT and Bard and I think my mistake has been to be a little too granular or specific in my prompts. In most cases it produced results that were inaccurate (ETA: or flat out demonstrably wrong) or only fulfilled a part of the prompt.
Was gonna say this too, it’s a great one for fact-checking. Sometimes it won’t include a source and make something up, just watch out for those.
