Nemotron-Labs Diffusion

NVIDIA Labs tri-mode LLM family: at each step the model can run as autoregressive, diffusion, or self-speculation, with a learned controller picking the regime. Reports 2.6–6.4× throughput over AR baselines while matching or beating Qwen3 accuracy on standard benchmarks.

Three sizes (3B / 8B / 14B), each with Base, Instruct, and VL variants; eight model uploads total on May 23. Released under the Nemotron Open Model License.
