Observation, Not Prediction: Conversation-Level Disaggregated Scheduling for Agentic Serving

arXiv:2606.01839v1 Announce Type: cross Abstract: LLM-based agents resolve a user task through many turns of dependent inference and tool calls, producing a workload whose total cost is unknown when the task arrives. Existing multi-turn systems keep the turn as the scheduling unit and decide, turn by turn, whether to disaggregate prefill from decode. That decision rests on the turn's decode length, tool behavior, and KV growth, quantities that are not observable when the scheduler must act, forcing the system to predict them. We show this dependence on prediction is imposed by the scheduling u

Why this matters
Why now

The proliferation of complex LLM-based agents necessitates more efficient and adaptive scheduling methods to handle their dynamic and unpredictable resource demands.

Why it’s important

This research addresses a fundamental bottleneck in scaling agentic systems, moving towards more robust and cost-effective deployment of advanced AI applications.

What changes

Scheduling decisions for agentic workloads move from reactive, prediction-based methods to proactive, observation-driven strategies, improving resource utilization and performance.
