nvidia/NVIDIA-Nemotron-3-Nano-30B-A3B-NVFP4

nvidia/NVIDIA-Nemotron-3-Nano-30B-A3B-NVFP4 is a nvidia record on this register. The Hugging Face model API lists the pipeline tag as text-generation. The safetensors index gives an exact parameter count of 18,237,772,608. Architectural context length (max_position_embeddings) is 262,144. The listed licence is other. The Hub repository was created on 20 Dec 2025, which is the release date this register uses.

Primary source: the Hugging Face model card for nvidia/NVIDIA-Nemotron-3-Nano-30B-A3B-NVFP4. Fields below come from that card, the Hub model API, and the repository’s own config.json when those files exist. A field we cannot source is omitted rather than guessed.
