Inference cost for Diffusion Language Models varies by task complexity
October 19, 2026
Diffusion language models exhibit variable generation costs because the number of forward passes depends on task difficulty. Open-ended writing requires over three times more passes than simple grammar correction, driven by token rarity and input novelty.
