    Use Cases & Benefits

    • Provides a unified platform for collecting data, training, and evaluating world models with model-predictive control across diverse standardized environments.
    • Enables reproducible research with reference implementations, multiple dataset formats, and extensive environment support including factors of variation for zero-shot generalization.
    • Use for developing and benchmarking world models in reinforcement learning research with standardized datasets and evaluation protocols.
    • Use for training and evaluating model-predictive control policies in robotics and control tasks using a variety of simulated environments.
    • Use for converting and managing large-scale datasets in different formats to optimize storage and throughput for machine learning workflows.

    From the README

    A platform for reproducible world model research and evaluation.

    stable-worldmodel provides a single, unified interface for the three stages of world model research — collecting data, training, and evaluating with model-predictive control — across a large suite of standardized environments. It ships with reference implementations of common baselines and planning solvers so research code can stay focused on the contribution that matters: the model and the objective.

    LeRobot dataset support is a separate opt-in extra (requires Python 3.12+): pip install 'stable-worldmodel[lerobot]'.

    Datasets and checkpoints are stored under $STABLEWM_HOME (defaults to ~/.stable_worldmodel/). Override the variable to point at your preferred storage location.

    The library is in active development. APIs may change between minor versions.

    Reference implementations are provided in scripts/train/: lewm.py implements LeWM, and prejepa.py reproduces DINO-WM. To train directly from HuggingFace object storage with no local dataset download, see the notebook.

    GPU utilization for LeWM trained with Push-T LanceDB dataset on a H200 GPU.
