Researchers have analyzed diffusion language models, specifically DiffusionGemma, to understand variations in their generation speed across different tasks and languages. They found that models spend more computational resources on novel, rare, or incorrect outputs, with tasks like open-ended writing being more costly than simple text editing or grammar correction. This per-token generation speed can serve as a signal to improve inference efficiency and reliability, for instance, by weighting candidate answers based on decoding speed to achieve better accuracy without additional computational cost.
