ThinkingVLA: Interleaved Vision and Language Reasoning for Robotic Manipulation

The paper frames the work as vlaModern Robot LearningVision-Language-Action model (VLA)A model that takes images and language as input and outputs robot actions.. Start here because it defines what success means and which assumptions the rest of the method inherits.

(what actions get there). The key insight is interleaving visual and textual reasoning in a single model—you predict a target image, then reason about how to reach it—which beats end-to-end actionCore ConceptsActionA command the robot sends to its motors, controller, or low-level system. prediction on long-horizon tasks like multi-step manipulationManipulation & TasksManipulationUsing a robot arm or hand to move or interact with objects..
