MAGE: Active Execution-State Management for Long-Horizon Agents

Save

In brief

  1. MAGE stores interactions in a hierarchical tree to track agent execution state.
  2. The system isolates errors and limits context growth for better performance.
  3. MAGE cuts token usage by 55.1% while raising task success rates by 7.8–20.4 percentage points.

Researchers introduce MAGE, a memory system for LLM-based agents that tracks execution state via a hierarchical tree. Unlike semantic similarity approaches, MAGE isolates errors and caps context growth, boosting performance and cutting costs.
