31岁的AI研究员Danijar Hafner于2025年秋季离开Google DeepMind，在旧金山SoMa区创办新初创公司1。该公司目前仍处于隐秘模式，配备多个从中国进口的人形机器人1。Hafner的核心技术基于模型的强化学习和世界模型，使AI智能体能够在无需真实环境试错的情况下学会规划和适应复杂任务1。
Hafner在AI领域已取得显著成就1。他开发的里程碑项目包括使智能体具备规划能力的PlaNet、达到Atari游戏人类水准的Dreamer 2、解决Minecraft采钻难题的Dreamer 3，以及实现离线学习的Dreamer 41。业界对他的能力评价极高——Google研究主管Timothy Lillicrap称其"轻易位居Google研究人员的前1%"1。Hafner曾与Geoffrey Hinton和Ashish Vaswani等AI领域传奇人物合作1。现在，他正致力于将这些虚拟世界的AI代理技术转移到物理机器人领域1。
Danijar Hafner, a 31-year-old AI researcher, has left Google DeepMind in fall 2025 to launch a startup in San Francisco's SoMa district focused on developing AI agents capable of planning and adapting to unfamiliar environments 1. The company, which remains in stealth mode, is equipped with multiple humanoid robots imported from China 1. Hafner's approach leverages model-based reinforcement learning and world models, enabling AI agents to learn complex tasks through simulated environments rather than through trial-and-error in physical settings 1.
Hafner's research trajectory demonstrates significant contributions to the field. His earlier work includes PlaNet, which established planning capabilities in AI systems, followed by the Dreamer series—Dreamer 2 achieved human-level performance on Atari games, Dreamer 3 solved Minecraft mining challenges, and Dreamer 4 enabled offline learning 1. Timothy Lillicrap has praised Hafner as ranking "easily in the top 1 percent of Google researchers" 1. Throughout his career, Hafner has collaborated with prominent figures in AI, including Geoffrey Hinton and Ashish Vaswani 1. The startup now aims to transition these AI agents from virtual environments to physical robotic applications 1.
