WhiFlash: Accelerating Speculative Decoding with Token-Level Cross-Paradigm Routing

arXiv:2606.07710v1 Announce Type: new Abstract: The autoregressive nature of large language models (LLMs) remains a significant bottleneck for inference, particularly in complex agentic workloads. While speculative decoding (SD) accelerates inference, current approaches rely on static drafting paradigms, utilising either autoregressive drafting models for reasoning or diffusion-based parallel drafting models for structured outputs. We empirically find that drafting accuracy fluctuates dramatically within a single sequence, leaving significant performance unrealised by static paradigms and coar

Why this matters
Why now

The continuous drive to optimize large language model inference for complex workloads, coupled with the limitations of existing speculative decoding paradigms, makes this a timely development.

Why it’s important

Improving LLM inference efficiency directly impacts the scalability and cost-effectiveness of AI applications, especially critical for the advancement of autonomous agentic systems.

What changes

This research introduces a dynamic approach to speculative decoding, moving beyond static methods to potentially unlock significant performance gains for LLM inference in agentic and complex tasks.
