A new study, "Actions Speak Louder than Words: Measuring Cross-Lingual Policy Retention in Tool-Using Agents," evaluated how tool-using agents perform when given tasks in different languages. The research found that while previous multilingual evaluations focused on final answers, the actual actions taken by the agents are crucial for understanding cost, latency, and failure modes. The study analyzed 2.38 million rollouts across 8 models, 6 benchmarks, and 41 languages, identifying and correcting five confounds that previously obscured true performance. AI
IMPACT Reveals that tool-using agents often default to English even when prompted in other languages, highlighting a critical area for improvement in multilingual AI capabilities.
