NVIDIA NeMo Data Designer

NVIDIA's proprietary synthetic-data generation service for building structured and unstructured training data with transformation and augmentation workflows. The productized form of Gretel's technology after NVIDIA's 2025 acquisition.

NVIDIA NeMo Data Designer (NeMo microservices), proprietary. Represents the synthetic-data capability of Gretel, which NVIDIA acquired in March 2025; the Gretel brand is retired (gretel.ai redirects to NVIDIA) and the gretel-synthetics OSS repo (Apache-2.0) was archived Feb 2026. Substituted for Gretel, which no longer exists as a standalone product. Confirmed 2026-07-21.

3.0

Backed by NVIDIA and distributed through the NeMo platform; Gretel had a large synthetic-data user base pre-acquisition. Directional; hard to separate from NeMo overall.
