ACE-Bench: Agent Configurable Evaluation with Scalable Horizons and Controllable Difficulty under Lightweight Environments

📰 ArXiv cs.AI

ACE-Bench is a new benchmark for evaluating agents with scalable horizons and controllable difficulty in lightweight environments

advanced Published 8 Apr 2026
Action Steps
  1. Identify the limitations of existing agent benchmarks, such as high environment interaction overhead and imbalanced task horizon and difficulty distributions
  2. Design a unified grid-based planning task that addresses these limitations, such as filling hidden slots in a partially completed schedule
  3. Implement ACE-Bench with scalable horizons and controllable difficulty to evaluate agent performance
  4. Use ACE-Bench to compare and improve agent architectures and training methods
Who Needs to Know This

AI researchers and engineers on a team benefit from ACE-Bench as it provides a more reliable and efficient way to evaluate agent performance, allowing them to focus on improving agent capabilities
