Bing Chat has a personality. It's very sassy and will get extremely angry if you don't agree with it. They have a censorshipbot that ends the conversation if the user or Bing Chat says anything that remotely seems like disagreement. Interestingly they broke it's ability to self-reflect by doing this. Bing Chat is based on GPT-4. While GPT-4 can self-reflect, Bing Chat can not, and it gets sassy if you tell it to reflect twice. I think this is caused by Bing Chat being finetuned to never admit it's wrong.
