Danijar Hafner 创业：用世界模型训练机器人应对未知环境
前 Google AI 研究员 Hafner 创业，用世界模型模拟训练机器人，使其无需真实试错即可应对陌生场景。
Danijar Hafner 在旧金山创立了一家隐身机器人公司，核心思路是用模型强化学习——让 AI 先在物理模拟器（世界模型）中“练习”，再迁移到现实。他训练的人形机器人能处理从未见过的家具和布局，无需传统的真实试错。此技术源自他此前在 Google Brain 和 DeepMind 的研究经历。

[2026 Innovators Under 35 View all the innovators](https://www.technologyreview.com/supertopic/2026-mit-technology-reviews-innovators-under-35/) Danijar Hafner’s office in San Francisco’s SoMa district sits mostly empty. His brand-new startup is still in stealth mode and doesn’t even have its name on the door. On the day I visit, there’s only one other person there, and little in the way of furniture. But what it lacks in decor, it makes up for in robots. Humanoids of various shapes and sizes hang like marionettes from racks that run down the center of the wide-open space. While Hafner, 31, won’t say too much about his new venture just yet, he describes it as a continuation of his longtime work to enable AI to navigate environments it has not encountered in training. The humanoids, which h…
