Teaching Diffusion to Speculate Left-to-Right

arXiv:2606.11552v1 Announce Type: new Abstract: Large language models (LLMs) achieve remarkable performance across a wide range of tasks, but their autoregressive decoding process incurs substantial inference costs due to inherently sequential token generation. Speculative decoding addresses this bottleneck by employing a lightweight draft model to propose multiple future tokens that are subsequently verified in parallel by a larger target model. Recent work has demonstrated that diffusion language models are well suited for this setting, as they can generate entire blocks of draft tokens in p

Why this matters
Why now

The continuous push for more efficient and powerful large language models necessitates innovations in their underlying architecture and decoding processes, making advancements in speculative decoding and diffusion models timely.

Why it’s important

Improving the inference efficiency of large language models directly impacts their operational cost, scalability, and the feasibility of deploying more complex AI systems, which is critical for all AI-driven sectors.

What changes

The ability of diffusion models to generate entire blocks of draft tokens and for speculative decoding to verify these in parallel could significantly reduce the computational bottleneck associated with autoregressive decoding in LLMs.
