Reducing Cost of LLM Agents with Trajectory Reduction

arXiv – CS AI|Yuan-An Xiao, Pengfei Gao, Chao Peng, Yingfei Xiong|
🤖AI Summary

Researchers introduce AgentDiet, a trajectory reduction technique that cuts computational costs for LLM-based agents by 39.9%-59.7% in input tokens and 21.1%-35.9% in total costs while maintaining performance. The approach removes redundant and expired information from agent execution trajectories during inference time.

Key Takeaways
  • AgentDiet reduces LLM agent computational costs by up to 59.7% in input tokens without performance loss.
  • The technique identifies and removes useless, redundant, and expired information from agent trajectories during execution.
  • Testing on coding agents showed 21.1%-35.9% reduction in total computational costs across two LLMs and benchmarks.
  • Efficiency concerns in LLM agent systems have been largely overlooked despite high computational costs.
  • Inference-time trajectory reduction represents a promising direction for optimizing agent system performance.
