Playing with the smaller free models, I’ve definitely found that they like to play along and mirror whatever you say. They’re great as a sounding board and active listener when you need to work through something, and they’re good for recalling facts that they know. They can be really useful when they glue together something you’re talking about and something relevant that they know. They’re terrible for anything that requires interoception or any kind of confidence estimation. They have no idea whether they’re recalling or confabulating.
