I find the first two responses "Perfect!..." and "Based on..." intensely annoying. They add nothing to the discussion and act as noise. This article crystalises a problem with AI: words are cheap to generate and expensive to read (just like spam). The AI should just do as it's asked and succinctly generate the poll. If asked "Why did you make these suggestions", it should explain why it chose those restaurants.
Edit: I'd also add that done "right" the AI should be clearly labelled as such. Its chat handle should include something like "AI", so the other chat users know exactly what they are dealing with, without having to know what "TripJam" or "TJ" is.
Unless it's a reasoning model with access to its own reasoning trace, any questions of "why did you choose X" will result in a rationalization, not an explanation. The model simply doesn't know why it made the suggestion otherwise.
