📰 ArXiv cs.AI

Learn to diagnose where and why agentic systems break on long-horizon tasks using the HORIZON benchmark

advanced Published 15 Apr 2026
Action Steps
  1. Read the HORIZON benchmark paper to understand its methodology and evaluation metrics
  2. Apply the HORIZON benchmark to your own agentic system to identify potential weaknesses
  3. Analyze the results to diagnose where and why your system breaks on long-horizon tasks
  4. Use the insights gained to modify and improve your system's architecture and training data
  5. Test and evaluate your modified system using the HORIZON benchmark to measure performance improvements
Who Needs to Know This

AI researchers and engineers working on agentic systems can benefit from this knowledge to improve their systems' performance on long-horizon tasks

Key Insight

💡 Agentic systems often break down on long-horizon tasks due to poorly characterized failures, but the HORIZON benchmark can help diagnose and improve performance
