GigaWorld from Giga AI is an open-source embodied interaction world model (GigaWorld-0) designed to generate highly generalizable embodied interaction data for data amplification, addressing the data scarcity of existing embodied foundation models. It builds high-fidelity, interactive embodied environments for end-to-end closed-loop simulation and reinforcement learning training, with precise future prediction capabilities that empower action learning and continual learning for embodied foundation models. It achieves geometric consistency and physical accuracy in world model modeling.
