Agentic World Action Models
The field of robotics has long wrestled with two parallel approaches to decision-making. World action models deliver visual foresight and future prediction for manipulation, yet they typically omit explicit mechanisms for reusing...
LongZero: Enhancing Long-Context Reasoning in LLMs from Zero Data
World models without compositional reuse Robotics research has settled into two contrasting paradigms. World action models deliver visual foresight and future prediction for manipulation, yet they typically omit explicit mechanism...
VoxProg: 3D Spatial Reasoning through Voxel Programming
Language models have grown surprisingly capable at following instructions, yet their ability to reason about three-dimensional spaces remains fragile. Interpreting spatial tasks in 3D scenes requires programs to construct geometri...
