The open-source robotics framework LeRobot has reached version 0.6.0, delivering one of its most feature-packed updates yet. The release focuses on three ideas captured in its tagline: imagine, evaluate and improve. It introduces policies that learn to predict the future, expands its catalogue of vision-language-action models, adds tools to measure success and makes training and data handling faster and lighter.
Policies That Learn to Imagine
A central question in robotics is whether world models — systems that anticipate what happens next — actually help robot policies perform better. Version 0.6.0 ships three new policies designed to explore that question, each balancing imagination with computational cost.
VLA-JEPA trains a compact model to predict future frames in latent space during learning, then drops the world model at inference so there is no extra runtime cost. Ready-to-use checkpoints, including a pretrained base for fine-tuning, are available on the Hub.
LingBot-VA goes further, predicting future video and actions together chunk by chunk while feeding real observations back in to stay grounded. Users can even save what the robot imagined and compare it to what actually happened, with inference running on a single 24–32 GB GPU. FastWAM pairs a video-generation expert with a compact action expert, learning to dream its own rollouts during training but skipping the dreaming at inference to denoise actions directly.
A Growing Model Zoo
The release expands LeRobot's collection of vision-language-action models (VLAs). The NVIDIA GR00T integration has been upgraded to GR00T N1.7, the newest open generation of the cross-embodiment foundation model, tested for parity against NVIDIA's original implementation. It replaces N1.5, which remains available by pinning an older version.
MolmoAct2 from the Allen Institute for AI is now fully supported, covering fine-tuning, evaluation and real-robot deployment, with checkpoints that can run zero-shot on SO-100/101 hardware. Inference fits in roughly 12 GB, while LoRA fine-tuning works on a single 24 GB GPU.
Other additions include EO-1, built on a Qwen2.5-VL-3B backbone; a Multitask Diffusion Transformer that brings the TRI Large Behavior Models recipe to LeRobot; and EVO1, a lightweight 0.77B-parameter policy small enough to run in real time on modest GPUs.
Knowing When a Robot Succeeds
Success detection and progress estimation have long been missing pieces of the robot learning loop. LeRobot now offers a unified reward models API that mirrors its policies interface, bundling four reward models behind a single system.
Robometer is a general-purpose, pretrained reward model that scores task progress and success from raw video and a language instruction, without task-specific training. It was trained on more than one million robot trajectories. TOPReward takes a fully zero-shot approach, wrapping an off-the-shelf vision-language model to turn any capable model into a reward function. Both come with labeling scripts that write per-frame progress curves into datasets.
