AgentServeSim: Serving-System Simulation and Policy Search for LLM Agent Programs
Large language model agents execute programs comprising multiple model turns interleaved with external tool calls. Their job completion time depends on how the serving system retains KV state across tool gaps, routes successor turns, and schedules competing programs. Most existing serving simulators operate on request streams in which arrivals are externally supplied and KV state follows request- or cache-scoped semantics. They therefore cannot jointly represent the cross-turn state and policy-dependent successor releases needed to evaluate counterfactual agent-serving trajectories. We present AgentServeSim, a simulator whose unit of execution is the agent program. A Program Control Block...
