ChatGPT had Santa mode last year where you could talk to Santa using Advanced Voice. I thought it was pretty cool because as adults we're used to turn-based conversation, speaking clearly, and waiting for a response.
That did not happen when I tried it with my nieces and nephews. Lots of screaming, incoherent AND I I I REALLY I WANT, yelling over Santa as he was responding, etc. It was a complete flop.
Anyway I would be astonished if this works well for younger kids.
