NVIDIA open-sources NeMo Data Designer: declarative synthetic data pipeline lifts Nemotron Nano v3 from 80.2% to 86.9%
dair_ai · x · 2026-09-18
- NVIDIA published a report on NeMo Data Designer, its open-source synthetic data tool
- Declarative config defines each dataset column; types include generated text, code, structured output, images, embeddings, and statistical samplers for diversity, extensible via plugins
- Workflow is preview-driven: generate a few records, inspect, adjust config, then run at full scale; runtime handles column dependencies, model endpoint calls, and retries
- Nemotron case study: 9K JSON-schema tasks built with NDD raised Nemotron Nano v3 from 80.2% to 86.9% on JSONSchemaBench
