Agent JIT Compilation

Agent JIT Compilation for Latency-Optimizing Web Agent Planning and Scheduling

This paper introduces agent just-in-time (JIT) compilation as an alternative to the sequential fetch-screenshot-execute loop used by current computer-use agents. The approach compiles natural language task descriptions directly into executable code that can include LLM calls, tool calls, and parallelization, using three components: JIT-Planner, JIT-Scheduler, and an invariant-enforcing tool protocol. Across five web applications, JIT-Planner achieves 10.4× speedup and +28% accuracy over Browser-Use, while JIT-Scheduler achieves 2.4× speedup and +9% accuracy over OpenAI CUA.
