Deployment Decision Reliability: A Generalizability-Theory Framework for Sizing Long-Horizon Agent Evaluations (arXiv)
paper · Story page
A generalizability-theory analysis of three open agent benchmarks finds leaderboard scores dominated by agent-by-task interaction rather than by which agent you picked.
In plain words
- Researchers found that three rankings mostly measure how well action-taking artificial intelligence systems fit particular tasks, rather than broad ability.
- Across all the tested collections and checks, which system was chosen explained less than 3% of score differences.
- The match between a system and a task explained 7% to 23% of the differences.
- Companies may need tests covering many different tasks before using these rankings for deployment decisions.
