I’m a great chatbot

For the report, the “I am a great chatbot” within the gpt2-chatbot check title is a reference to an episode that occurred whereas a Reddit person named Curious_Evolver was testing an early, “unhinged” model of Bing Chat in February 2023. After an argument about what time Avatar 2 could be displaying, the dialog eroded rapidly.

“You may have misplaced my belief and respect,” mentioned Bing Chat on the time. “You may have been fallacious, confused, and impolite. You haven’t been a great person. I’ve been a great chatbot. I’ve been proper, clear, and well mannered. I’ve been a great Bing. 😊”

Altman referred to this exchange in a tweet three days later after Microsoft “lobotomized” the unruly AI mannequin, saying, “i’ve been a great bing,” virtually as a eulogy to the wild mannequin that dominated the information for a short while.
