X-CoSD: Communication-Efficient Cross-Vocabulary Collaborative Speculative Decoding

The paper introduces X-CoSD, a communication‑efficient framework for collaborative speculative decoding that allows a small on‑device language model to draft tokens while a server‑side large language model verifies them, even when the two models use different vocabularies. X-CoSD employs hybrid resampling to limit distribution exchange to only the common vocabulary, and its enhanced variant X-CoSD‑E further reduces communication by sending only server‑sampled replacement candidates for device verification. Both variants preserve the server model’s distribution and, according to experiments, accelerate token generation without sacrificing quality.

ASPIRE: Asynchronous Batched Self-Speculative Decoding for Long-Context LLM Inference

ASPIRE introduces a non‑synchronized batched self‑speculative decoding framework for long‑context LLM inference, addressing the memory bottleneck of attention by drafting tokens with sparse attention and verifying them with full attention. It combines a unified mixed forward pass, a lightweight online speculation scheduler that lets each request independently decide when to verify, and an intra‑draft refresh layer that updates the sparse context at every draft step. Experiments on three models and five benchmarks show 1.70–4.58× speedup over autoregressive baselines and a 27% average improvement over the strongest prior self‑speculative methods.
