Tencent QQ has launched the 'AI Chat Buddy' feature, which allows users to engage in AI conversations. Users can access this feature through the QQ sidebar under Membership - Chat Buddy, which includes different types of virtual characters for companionship, storytelling, challenges, MBTI, and celebrities. Users can choose one character to add as a friend and chat in real-time. Characters include Tesla CEO Elon Musk, Li Bai, Socrates, Bald Strong, Nobita Nobi, and Doraemon, among others. There is a daily limit on chat interactions, with regular users allowed 100 messages per day and super members allowed 400.
