MASPO: Optimizing Prompts for LLM-Based Multi-Agent Systems

ai-technology · 2026-05-09

Researchers have introduced MASPO, a framework for automatically optimizing prompts in LLM-based multi-agent systems. The key innovation is a joint evaluation mechanism that assesses prompts based on their contribution to downstream agent success, not just local validity. This bridges local interactions and global goals without ground-truth labels. MASPO uses a data-driven evolutionary beam search for efficient prompt refinement.

Key facts

  • MASPO is a framework for joint prompt optimization in LLM-based multi-agent systems.
  • It addresses misalignment between local agent objectives and holistic system goals.
  • Core innovation: joint evaluation mechanism assessing prompts by downstream success.
  • Does not rely on ground-truth labels.
  • Uses data-driven evolutionary beam search.
  • Aims to improve complex collaborative tasks.
  • Prompts are role-specific for each agent.
  • Framework is iterative and automatic.
