SpecFold for Faster Diffusion Language Model Decoding
October 5, 2026
SpecFold accelerates Diffusion Large Language Models (DLLMs) by exploiting computational redundancy across multi-branch speculative decoding steps. By identifying shared hidden states between parent and draft branches, it reduces the total compute required for verification.
