Why Larger Blocks Hurt Diffusion Language Model Inference and How T* Solves It

The article analyzes the trade‑off in masked diffusion language models where larger generation blocks increase parallelism but degrade reasoning, and shows how the T* progressive block‑scaling method using trajectory‑aware reinforcement learning stabilizes training and boosts accuracy across block sizes, with up to 15 % gains on MATH500.
