PIVOT: Bridging Planning and Execution in LLM Agents via Trajectory Refinement

ArXiv CS.AI10h ago
auto_awesomeAI Summary

PIVOT is a self-supervised framework that improves LLM-based agents by iteratively refining their action plans through environment interaction, addressing the critical gap between planning and real-world execution. This approach tackles a fundamental limitation in current AI agents: their tendency to generate theoretically sound plans that fail when actually executed due to infeasible actions and constraint violations.

Key Takeaways

  • PIVOT treats trajectories as optimizable objects refined through self-supervised learning and environment feedback.
  • Current LLM agents fail execution despite coherent plans due to infeasible actions and constraint violations.
  • Framework comprises four components enabling iterative plan inspection and evolution for robust agent behavior.

New framework helps AI agents execute plans successfully by learning from failures.

trending_upWhy It Matters

This research addresses a critical bottleneck in deploying LLM agents for real-world tasks. By bridging the gap between planning and execution, PIVOT could significantly improve the reliability and practical utility of AI agents across applications requiring extended action sequences, from robotics to complex task automation.

FAQ

How does PIVOT differ from standard LLM agent approaches?expand_more
PIVOT treats entire action trajectories as refinable objects through iterative environment interaction, rather than relying solely on initial planning. This self-supervised approach learns from execution failures to improve future performance.
What types of problems does PIVOT solve?expand_more
PIVOT addresses plan-execution misalignment issues including infeasible actions, constraint violations, and error accumulation over extended decision horizons in LLM-based agents.
