ACE ROBOTICS announced on 15 June 2026 that its open-source Kairos world model achieved leading results across four global embodied-intelligence benchmarks: RoboTwin 2.0, LIBERO-Plus, WorldModelBench Robot and DreamGen. Kairos ranked first among evaluated world models and vision-language-action (VLA) systems on these benchmarks' public leaderboards as of 12 June 2026, leading across core capabilities including complex robotic manipulation, scene-level generalization, physical-world modeling and zero-shot transfer. On LIBERO-Plus, a scene-level generalization benchmark, Kairos achieved an overall score of 89.0, ranking first and surpassing ACoT-VLA (88.0), Pi 0.5 (85.7), ProGAL-VLA (85.5) and the Being-H0.7 world model (84.8). It showed near-ceiling performance on lighting (97.7), noise (96.8) and background (95.8). On WorldModelBench Robot, Kairos-4B achieved an overall score of 9.30, ranking first with only 4 billion parameters, outperforming larger systems including a 28-billion-parameter Lingbot and a 16-billion-parameter Cosmos. The project is openly available on GitHub, Hugging Face and ModelScope.
