SpecBox: Speculative Sandbox Scheduling for Efficient LLM Agent Serving
Quick summary
arXiv:2607.23933v2 Announce Type: replace-cross Abstract: As LLM agents increasingly rely on the Model Context Protocol (MCP) to invoke isolated external sandboxes, disaggregated sandbox deployment introduces a fundamental tension between resource utilization and interactive tail latency. Persistent long-lived sandbox reservations incur excessive memory overhead at scale, while lazy on-demand instantiation generates severe cold-start penalties that degrade response performance under multi-tenant, multi-turn agent workloads. To resolve this dilemma, we present SpecBox, a runtime built around sp

Why it matters
“SpecBox: Speculative Sandbox Scheduling for Efficient LLM Agent Serving” shows why AI risk cannot be reduced to answer accuracy. Access controls, logging, human approval and incident response need to be designed into the workflow from the start.
