🤖 AI Summary
This work addresses the challenge that existing AI systems struggle to dynamically observe, intervene in, and optimize agent behavior at runtime, making it difficult to simultaneously achieve high task success rates, low latency, token efficiency, reliability, and safety. To overcome this limitation, the paper proposes a novel runtime infrastructure layer situated between the model and the application, which treats the AI execution process itself as an optimizable object—departing from conventional approaches that restrict optimization to static model or log-level adjustments. This layer enables proactive intervention and multi-dimensional performance co-optimization through mechanisms such as runtime monitoring, real-time inference, adaptive memory management, fault recovery, and policy enforcement. Experimental results demonstrate that the proposed approach significantly enhances the holistic performance of long-horizon agent workflows across task success rate, response latency, token efficiency, system reliability, and safety compliance.
📝 Abstract
We introduce AI Runtime Infrastructure, a distinct execution-time layer that operates above the model and below the application, actively observing, reasoning over, and intervening in agent behavior to optimize task success, latency, token efficiency, reliability, and safety while the agent is running. Unlike model-level optimizations or passive logging systems, runtime infrastructure treats execution itself as an optimization surface, enabling adaptive memory management, failure detection, recovery, and policy enforcement over long-horizon agent workflows.
