arXiv:2510.01336v2 Announce Type: replace-cross Abstract: Speculative decoding accelerates LLM inference by using a smaller draft model to speculate tokens that a larger target model verifies. Verification is often the bottleneck (e.g. verification is $4\times$ slower than token generation when a 3B model speculates for a 70B target model), but most prior works focus only on accelerating drafting. $\textit{``Intermediate"}$ verification reduces verification time by discarding inaccurate draft tokens early, but existing methods incur substantial training overheads in incorporating the intermedi
The continuous push for more efficient and faster LLM inference aligns with the rapid development and deployment cycles of AI models, making optimization a critical current focus.
Accelerating LLM inference directly reduces operational costs and enables more responsive, scalable AI applications, impacting the economics and practicality of large-scale AI deployment.
This advancement changes the bottleneck in speculative decoding from verification speed to overall efficiency, potentially increasing the effective compute available for LLMs without requiring more hardware.

Faster LLM inference reduces the computational cost of deploying large language models.
Lower costs could accelerate the adoption and integration of sophisticated AI models into a wider array of products and services.
Increased accessibility and efficiency of LLMs might lead to the emergence of novel AI agentic systems or more complex autonomous applications.
