The word "lie" is probably too anthropic here. I should have just said "made up". There is no intent to lie. And the model isn't try to self-fact-check anyway. (Maybe some do). But if they do they are probably bad at it at the moment, at least from my experience of GPT3.5 (not used 4 much).
Can anyone recommend a good, and trusted UI so I can use it via the API? I don't want to pay monthly for it, but would be nice to use occasionally. I keep meaning to do this!
