Nexus system enhances agentic LLM efficiency with novel KV-cache splicing

Researchers have developed Nexus, a system designed to improve the efficiency of agentic large language models (LLMs) by optimizing how they handle tool schemas and KV caches. Nexus decouples tool routing from schema pre-filling, using a semantic lookaside buffer to select tools, which maintains high accuracy even with a large number of tools. Additionally, it incorporates a depth-adaptive method for splicing KV cache blocks into the live context, repairing attention corruption caused by rotary position embedding phase drift to ensure output fidelity.
