LeRobot v0.6.0: Imagine, Evaluate, Improve

LeRobot v0.6.0 is a software release focused on robot learning that introduces three main capabilities: world model policies that learn to predict future outcomes before acting, reward models that assess when a robot succeeds, and evaluation benchmarks to measure performance. The release addresses what the robotics field is asking: whether world models actually help robot policies work better. The update also adds new vision-language-action models, faster data loading with depth sensing support, automated language annotations for datasets, and deployment tools that can incorporate human corrections to improve training data.
