NextFin News -- ACE Robotics has announced the open-source release of the "Kairos 3.0 - 4B" world model. This is the first world model capable of driving embodied intelligence for on-device control. Its inference speed is 72 times faster than NVIDIA's Cosmos 2.5, and the same model is compatible with various robotic forms, including single-arm, dual-arm, and dexterous hands. ACE Robotis was founded by Wang Xiaogang, the co-founder of SenseTime in late 2025. The startup completed its angel round of financing earlier this week.
