Leyline: KV Cache Directives for Agentic Inference
Leyline introduces a new serving-side primitive for managing KV cache in agentic LLMs, enabling efficient content editing and removal without full re-computation. The system uses declarative directives and RoPE-rotation corrections to handle policy-driven cache modifications, improving cache efficiency by 11.2 percentage points and agent solve rates by 14.3 percentage points.
