2. New paper proposes a comprehensive framework for measuring AI agent reliability. (title shortened)
evaluations, ai-safety - research, safety, production - May 11, 2026
What changed? We found that reliability has improved only modestly over 18 months, while accuracy improved substantially. All three major providers cluster together, so this appears to be an industry-wide limitation (though there are some cases where Anthropic’s models outperform OpenAI’s and Google’s).
