A new paper from arXiv introduces a method to improve the reliability of AI agents in computer tasks by focusing on their ability to stop, not just initiate actions. Researchers developed a verifier-guided repair process for a 35B agent across five environments, revealing that evaluation variance is negligible and training seed effects are small. The study found that success rates are primarily influenced by data draw and run-to-run nondeterminism, with a bimodal distribution in harder tasks indicating a significant chance of failure modes. The paper also proposes a library, `cua_reliability`, for reporting results across multiple seeds to ensure more robust evaluations. AI
