NVIDIA recently released Nemotron-Labs-TwoTower, a diffusion language model built on the pretrained autoregressive backbone Nemotron-3-Nano-30B-A3B. The model is released as open weights under the NVIDIA Nemotron Open Model License. This release addresses the throughput bottleneck in text generation, as autoregressive models decode one token at a time, limiting speed due to sequential processing. In contrast, discrete diffusion language models offer a potentially more efficient alternative.
