Introduction
Block Diffusion Language Models (BD-LMs) improve diffusion-based text generation with KV caching and flexible-length generation. MBD-LMs extend them from Single-Block Diffusion (SingleBD) to Multi-Block Diffusion (MultiBD), allowing a running-set of consecutive blocks to be decoded concurrently for inter-block parallelism.
To train these models, the authors propose Multi-block Teacher Forcing (MultiTF), which post-trains BD-LMs with randomized noise-schedulers that better match MultiBD inference states.
