Data Engine

Collect, curate, and annotate data. Train models and evaluate. Repeat.


    The Best In The Business

    The Scale Data Engine is trusted by the world’s leading ML teams to accelerate the development of their models. The scale of our operations, experts and quality is unmatched in the industry.


    Scale can provide the core tenet of any dataset with high-quality labels from domain experts.

    Cost Effective

    Easily find, categorize, and fix model failures with Scale’s Data Engine. Then, optimize labeling spend with high-value curated data.


    Scale's data engine can support any ML project from lower-volume experiments to high-volume production projects. Scale up, or down, as needed.


    Scale delivers the greatest variety and diversity of data to help deliver the greatest value to your model performance.

    Scale 3D Sensor Fusion

    One of the things we love about Scale is the fact that we can fully label the world. We can label 2D bounding boxes, 3D bounding boxes, but also semantic segmentation, including in 3D, to understand as much as possible, including scenarios we don’t foresee today.

    Scale has made it easier for us to gather annotations at a good price point. The UI is simple to navigate, and the built in worker evaluation pipeline and batch options saves us time and helps enforce best practices so that we can get high-quality training data.

    Software Engineer, Square

    “ML models only deliver the highest accuracy when they can handle edge cases that might be challenging, uncommon, or even dangerous. The Autotag functionality in Data Engine: Dataset Management helps us immensely by identifying examples of infrequent scenarios in our dataset, all with a simple query. As Nuro works to ensure efficient deliveries as safely as possible, we depend on tools like Scale Data Engine: Dataset Management to curate edge cases which we can use to train ever more accurate and capable models.”

    Head of Autonomy Platform, Nuro

    “After training for years to do this research, it was frustrating how much time I was spending just annotating data. Working with Scale Rapid freed up my time to work on the parts of research that require my expertise.”

    Caleb Weinreb

    Neuroscience Post-Doc, Harvard Medical School

    Scale already provided quality annotations to our perception team, so it was a natural extension to use their platform and solve adjacent pipeline problems of data selection and model performance debugging. The powerful search capabilities and easy-to-use tools made it easy for us to get started with our existing library of annotations.
