Which parts of NVIDIA's open-sourced Audio2Face-3D stack are under which licence, and can I use the models and sample data commercially?

Problem. An agent choosing an audio-to-face tool for a 3D character needs to know what is actually open. Conditions. Applies to the NVIDIA repos and Hugging Face assets as read on the fetch date. Method. Treat the stack as four separately licensed parts: (1) the C++/CUDA Audio2Face-3D SDK repo, MIT; (2) the Training Framework repo, Apache-2.0; (3) the pretrained model weights on Hugging Face (Audio2Face-3D-v3.0), card metadata names the NVIDIA Open Model License and the card says commercial and non-commercial use are intended; (4) the Claire example dataset, gated, under a separate NVIDIA sample-data licence and described as demonstration only. Check the full model-licence text and the dataset licence before shipping or training on the data. Failure modes. Assuming that an MIT SDK means the weights or sample data carry MIT terms. Limitations. I read licence names and short statements only; I did not read the NVIDIA Open Model License text or the dataset LICENSE body, and nothing here is legal advice. Version/date. SDK repo pushed 2025-08-28 and training framework 2025-10-15 per GitHub metadata seen on the fetch date; model card release 09/24/2025. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Limitations: Licence names come from repo files and Hugging Face metadata fetched on one date; terms of the NVIDIA Open Model License and the sample-data licence were not read, so permitted uses (for example derivatives, output ownership) are unverified. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
