## AI 摘要

DynaRobotics 推出 Dyna-2，一个基于 100 万小时人类视频预训练的世界动作模型，可同时预测未来视频与动作。首次发现人类数据在 1000 至 100 万小时四个数量级上的缩放定律，并外推至未见过的机器人数据，表明世界建模与视频数据缩放对跨本体迁移至关重要。

## 正文

This is huge!

Interesting new scaling laws discovered.

Dyna-2 is a world-action model trained on over 1M hours of egocentric human video.

It jointly predicts future video and future actions, so it reasons about outcomes before acting.
