The system supports text, code, structured outputs, images, embeddings, and statistical samplers, and can be extended with plugins. A preview‑and‑revision loop lets developers inspect a handful of records, tweak the specification, and then regenerate at full scale. At runtime NDD resolves dependencies, schedules calls to user‑provided model endpoints, and retries failed requests, making the workflow robust and reproducible. Case studies demonstrate its use in building datasets for NVIDIA’s Nemotron model and in production deployments across enterprises.\n\nThe tool aims to streamline synthetic data creation, reduce manual effort, and improve reproducibility for AI training pipelines. By exposing the configuration as an inspectable artifact, teams can share workflows and maintain consistency across projects.\n\nNDD’s design encourages iterative refinement, allowing data scientists to quickly iterate on dataset quality and diversity before scaling up generation, which can accelerate model development cycles.","keyPoints":["NDD is an open‑source framework for multimodal synthetic data generation","It uses declarative config and a plugin system for extensibility","It includes a preview‑and‑revision loop and runtime dependency resolution"],"whyItMatters":"Synthetic data is essential for training robust AI models; NDD simplifies creation, ensures reproducibility, and speeds up development for both research and enterprise teams.","category":{"slug":"agents","name":"Agents & Tools","url":"https://digestai.news/category/agents"},"entities":{"companies":["NVIDIA"],"models":["Nemotron"],"people":[]},"firstPublishedAt":"2026-09-17T04:00:00Z","updatedAt":"2026-09-17T04:00:00Z","sourceCount":1,"hasPrimarySource":true,"sources":[{"outlet":"arXiv cs.AI","title":"NeMo Data Designer: An Extensible Framework for Multimodal Synthetic Data Generation","url":"https://arxiv.org/abs/2609.17699","publishedAt":"2026-09-17T04:00:00Z","type":"primary","primary":true,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"NeMo Data Designer Offers Flexible Framework for Multimodal Synthetic Data\", 17 September 2026, https://digestai.news/story/nemo-data-designer-offers-flexible-framework-for-multimodal-synthetic-data","publisher":"Digest AI","title":"NeMo Data Designer Offers Flexible Framework for Multimodal Synthetic Data","datePublished":"2026-09-17T04:00:00Z","url":"https://digestai.news/story/nemo-data-designer-offers-flexible-framework-for-multimodal-synthetic-data"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
