Hi all- I’m a co-founder from Gretel; our team and tech are now part of NVIDIA.

NeMo Data Designer is our core product from Gretel and now the internal framework we use heavily for both pre- and post-training data in Nemotron for a variety of use cases.

The OSS version is fully general-purpose: Python-first, modular, and designed so you can mix statistical samplers, LLM columns, and seed datasets in a single pipeline.

Happy to answer questions or hear feedback on missing features
