Bole system accelerates hybrid-attention LLM inference with tree speculation

Researchers have developed Bole, a new system designed to accelerate inference for hybrid-attention large language models. These models combine full attention with recurrent linear attention to manage long contexts more efficiently. Bole addresses the memory-bound nature of autoregressive decoding in these models by transforming the linear-attention recurrence into a tree-structured form, enabling parallel verification of speculative proposals. This approach significantly reduces transient memory usage and increases GPU capacity for key-value caches, leading to substantial improvements in decoding throughput and reductions in time-to-first-token for agent workloads.
