Efficient Diffusion LLMs via Temporal-Spatial Parallel Decoding and Confidence Extrapolation
arXiv:2605.30753v1 Announce Type: new Abstract: Diffusion-based large language models (dLLMs) support parallel text generation via iterative denoising, yet inference remains latency-heavy because many steps are spent on redundant refinement and repeated remasking of tokens whose final values are already determined. Prior acceleration methods mainly depend on step-local confidence heuristics or fixed schedules, which are sensitive to prompt and task variation and ignore strong positional effects within a sequence. We cast diffusion decoding as a dynamic control problem and show that token-wise
The continuous push for more efficient and powerful AI models, particularly LLMs, drives research into optimizing their core operations as their computational demands grow.
Sophisticated readers should care because this innovation directly addresses a critical bottleneck in deploying large language models, making them faster and potentially more accessible.
The method of inference for diffusion-based LLMs changes, moving from inefficient, fixed schedules to dynamic, confidence-based decisions, significantly reducing latency.
