About
DataDesigner is an open-source library developed by NVIDIA NeMo for generating high-quality synthetic datasets. It allows users to create diverse data from scratch or by leveraging existing seed datasets, going beyond simple LLM prompting. The tool provides a flexible framework for building production-grade synthetic data, enabling control over relationships between fields with dependency-aware generation. It includes built-in Python, SQL, and custom local/remote validators for quality assurance, and can score outputs using LLM-as-a-judge. DataDesigner also offers a preview mode for quick iteration before full-scale generation and supports agent-assisted development, particularly with Claude Code, for schema design and generation.
