Jin Wenyi, former President of miHoYo International, has joined Moonshot AI to spearhead Kimi's global expansion efforts. Following the release of the Kimi K3 model, Moonshot AI has launched the K399 web game platform. This platform features a variety of web games developed with the K3 model, spanning genres such as shooting, music, and 3D puzzles, with some games offering AI auto-play capabilities. K399 aims to demonstrate the K3 model's prowess in game generation and multimodal capabilities, offering a "one-sentence game generation" process for users. However, the platform has faced criticism for replicating existing games like The Legend of Zelda and Black Myth: Wukong, raising concerns about copyright issues and the quality of AI-generated content. Efforts to enhance platform review and legal governance are ongoing.
