On July 15th, Musk's Grok 4 large model unveiled its AI companion mode, featuring a Gothic-inspired girl named Ani as the inaugural character. Her distinctive golden pigtails, fishnet stockings, and bold dialogue quickly garnered widespread attention on social media. Within 48 hours, user-generated animations and cosplay creations featuring Ani dominated major platforms. Simultaneously, Cai Haoyu, the founder of MiHoYo, is leveraging his startup company Anuttacon to test the dialogue depth of his AI character Stella through the space survival game "Whispers from the Star." Stella, an astrophysicist stranded on an alien planet, requires players to employ their wit and cunning to aid her in survival.
