We took a 30B model and split it in two to write tokens in parallel instead of one at a time.Introducing Nemotron-Labs-TwoTower: a diffusion language model from NVIDIA Research adapted from Nemotron-3-Nano-30B-A3B. Here’s how it works: one half holds the context, the other writes the tokens, with both reusing the pretrained model instead of training a new one from scratch.We found it kept 98.7% of the original model’s quality at 2.42× faster generation.
