Odyssey 发布基础世界模型 Odyssey-3,称其可控制机器人、驱动人形、驾驶车辆、训练 AI、操控无人机甚至玩视频游戏。其路线是先用预训练世界模型,再接上用数十小时机器人演示训练的动作解码器;据作者转述,驾驶策略仅用 20 小时模拟数据训练后就能驶上印度真实街道,机械臂、人形遥操作和模拟无人机数据的用量也仅为数十小时。

This is potentially a great news for robot learning:

Odyssey-3 (a foundation world model) just dropped and its attacking robotics' biggest bottleneck, task-specific data.

Odyssey's approach is to start with a pretrained world model, then attach an action decoder trained on tens of hours of robot demonstrations.

Odyssey-3 drove real Indian streets after its driving policy trained on only 20 hours of simulation.

A lot of physical AI progress still comes from throwing more demonstrations at one narrowly defined system. Odyssey is arguing that broad world-model pretraining can absorb much of the knowledge that every downstream policy would otherwise need to relearn.

Their reported numbers are early but unusually small: tens of hours for robot arms, tens of hours of humanoid teleoperation, 20 hours of simulated driving, and tens of hours of simulated drone data.

The adaptation layer then learns how to turn Odyssey-3's representations into the actions of that specific system.

This is basically a data-allocation bet. Spend the huge pretraining budget once on a general model of the world, then spend far less experiential data teaching each new body its controls.

Today we’re unveiling Odyssey-3, a big step forward for foundation world models. It can control robots, power humanoids, drive cars (on the roads of India!), train AIs, pilot drones, and even play video games. We can’t wait to see what intelligent systems it enables.
