# LLaDA-UI: Bringing Block-wise Diffusion to Vision-Language GUI Agents > Source: > Published: 2026-09-15 02:30:00+00:00 Diffusion large language models (dLLMs) achieve high decoding efficiency through block-parallel, arbitrary-order generation, making them attractive for latency-sensitive applications. GUI agents represent a natural testbed for this paradigm, as they must repeatedly perceive screen states and emit st
