NeMo Data Designer: extensible open-source framework for multimodal synthetic data (arXiv:2609.17699v1)
The paper introduces NeMo Data Designer (NDD), an open-source, general-purpose framework for multimodal synthetic data generation that provides a declarative configuration format for dataset columns (text, code, structured outputs, images, embeddings, statistical samplers), a plugin system for extensions, and a built-in preview-and-revision loop for iterative dataset design. At runtime NDD resolves dependencies, schedules calls to user model endpoints, retries failures, and the authors present case studies including datasets used in Nemotron model development and in production enterprise deployments.
KEY POINTS
- The paper introduces NeMo Data Designer (NDD), an open-source, general-purpose framework for multimodal synthetic data generation that provides a declarative configuration format for dataset columns (text, code, structured outputs, images, embeddings, statistical samplers), a plugin system for extensions, and a built-in preview-and-revision loop for iterative dataset design.
- At runtime NDD resolves dependencies, schedules calls to user model endpoints, retries failures, and the authors present case studies including datasets used in Nemotron model development and in production enterprise deployments.
- NDD provides an inspectable, extensible, and production‑oriented SDG workflow that can speed iterative dataset creation and improve reproducibility for multimodal model development and enterprise use.
