About
NVIDIA Nemotron-Labs-Diffusion 3B is the smallest instruct model in NVIDIA Research's diffusion language model family, released May 23, 2026. Uses diffusion-based parallel decoding — generating multiple tokens simultaneously and iteratively refining them — enabling up to 6× higher throughput than autoregressive baselines. Supports three decoding modes: autoregressive, diffusion (block-by-block), and self-speculation (draft + verify). Trained on 1.3T tokens from NVIDIA Nemotron Pretraining datasets plus 45B fine-tuning tokens. Released under NVIDIA Nemotron Open Model License (commercially usable open weights). Available on Hugging Face at nvidia/Nemotron-Labs-Diffusion-3B.
Nemotron-Labs-Diffusion 3B is an open-weight model in the Nemotron-Labs-Diffusion family. The structured metadata tracks a 131k-token context window. No headline benchmark score is tracked for Nemotron-Labs-Diffusion 3B yet.
