NVIDIA Synthetic Data Generation

NVIDIA synthetic data generation for open datasets is its practice of artificially generating training data (text, code, math, and multimodal) and releasing it under permissive licenses, giving developers full visibility into the data instead of relying on opaque corpora. It generates this data two ways: model-based generation, where generator and reward models produce and filter examples in the NeMo framework (as in the Nemotron program), and simulation plus world foundation models, where tools like Omniverse, Isaac Sim, and Cosmos build physically accurate scenes and render them into photorealistic, labeled data. The result is one of the largest open contributions in the field, spanning language and reasoning (Nemotron), physical AI and robotics (Cosmos and Isaac GR00T), autonomous vehicles, and biomedical AI (Clara), each published alongside the model weights and recipes that created it.
