NVIDIA has unveiled Nemotron-TwoTower-30B-A3B-Base-BF16, a novel diffusion-based language model that diverges from traditional autoregressive generation. Instead of generating tokens sequentially, it employs a frozen autoregressive context tower paired with a diffusion denoiser tower that fills blocks of tokens in parallel. This approach aims to improve efficiency and scalability while retaining 98.7% of the original model's performance. The model is built on the Nemotron 3 Nano 30B-A3B backbone and uses BF16 precision for inference.
