Kairos: A Native World Model Stack for Physical AI
ACE Robotics
Kairos is a full-stack world model architecture for physical AI, introducing a Cross-Embodiment Data Curriculum (open-world video → human behavior → robot interaction) and a Hybrid Linear Temporal Attention mechanism with provable error-accumulation bounds. The 4B-parameter model runs on-device in real time and tops four embodied-intelligence benchmarks including RoboTwin 2.0 (96.1%) and LIBERO-Plus.
