arXiv:2606.12243v1 Announce Type: new Abstract: Speculative decoding (SD) addresses the high inference costs of LLMs by having lightweight drafters generate candidates for large verifiers to validate in parallel. Existing draft-verify methods use binary decisions: accept or fully recompute. Yet we find that many rejected tokens can be verified correctly by a slim submodel derived from the full verifier via intra-model routing, instead of the full verifier. This motivates our slim-verifier to handle tokens requiring moderate verification resources, reducing expensive large-model calls. We propo
The continuous drive to reduce the computational cost and increase the speed of large language model (LLM) inference necessitates innovative approaches like VIA-SD to optimize widely adopted techniques such as speculative decoding.
This breakthrough offers a method to significantly enhance LLM efficiency and throughput by intelligently managing verification resources, making advanced AI more accessible and scalable.
Existing speculative decoding methods, limited to binary accept/reject decisions, are replaced by a more nuanced approach that leverages intra-model routing to 'slim verifiers,' thereby reducing expensive full-model calls.
