New VLA models LaST-R1 and DIAL enhance robotic manipulation with advanced reasoning

By PulseAugur Editorial · Summary by gemini-2.5-flash-lite from 3 sources

Two new research papers introduce advanced Vision-Language-Action (VLA) models for robotic manipulation. LaST-R1 integrates latent Chain-of-Thought reasoning with reinforcement learning to improve adaptability and generalization, achieving a 99.8% success rate on the LIBERO benchmark. DIAL decouples high-level intent from low-level action execution using latent world modeling, enabling it to learn with 10x fewer demonstrations and generalize to real-world tasks. AI
