Kairos: A Native World Model Stack for Physical AI

arXiv:2606.16533v1 Announce Type: new Abstract: World models are transitioning from passive visual generators to foundational, operational infrastructure for Physical AI: they must natively acquire world knowledge from heterogeneous experience, maintain persistent states over long horizons, and execute efficiently within real deployment constraints. We introduce Kairos, a native world model stack designed around these requirements. (1) Kairos learns the world by pioneering a Native Pre-training Paradigm governed by a Cross-Embodiment Data Curriculum, which organizes open-world videos, human be

Why this matters
Why now

The development of Kairos signifies a pivotal moment as world models transition from theoretical concepts to practical, robust infrastructure for Physical AI, driven by the increasing demand for autonomous systems.

Why it’s important

A robust, native world model stack capable of acquiring and maintaining knowledge over long horizons is crucial for unlocking the full potential of physical AI, enabling more adaptive and efficient autonomous systems.

What changes

Current world model limitations in acquiring heterogeneous data and maintaining state over long periods are addressed, suggesting a future where physical AI can operate with greater autonomy and generalizability.
