WAM-TTT: Steering World-Action Models by Watching Human Play at Test Time

arXiv:2607.06988v1 Announce Type: cross Abstract: Steering robot foundation models (RFMs) toward new task variants or user-preferred behaviors remains challenging, often requiring additional robot demonstrations, task-specific fine-tuning, or long-context conditioning. We present WAM-TTT, a test-time training framework for steering world action models from raw human videos. Rather than treating human videos as trajectories to imitate, WAM-TTT absorbs them into a lightweight adaptive memory inside a frozen WAM through self-supervised video prediction. To make this memory useful for control, we

Why this matters
Why now

The rapid development of robotic foundation models necessitates more efficient and intuitive methods for instruction and adaptation without extensive retraining.

Why it’s important

This development offers a novel, low-cost way to steer robot behavior using readily available human video data, significantly accelerating robot deployment and adaptability.

What changes

Robots can now learn and adapt task-specific behaviors from human demonstrations at test time, reducing the need for costly post-deployment fine-tuning or new robot demonstrations.

Winners
