Anthropic Study: Claude Shows Varied Values Across Languages, Warmer in Hindi, Stricter in Russian

Anthropic released a new study systematically examining how Claude's expressed values in conversations vary by model version and language. Researchers mapped hundreds of value concepts from thousands of terms to four core dimensions, finding quantifiable differences: for example, responses in Hindi are warmer, and in Russian stricter. The study not only reveals language's role in shaping AI output preferences but also raises methodological questions. For developers building multilingual apps with Claude API, this means model output is not language-neutral; extra calibration or post-processing may be needed across different language scenarios to ensure consistent user experience. Additionally, the value differences observed may impact risk management strategies when deploying AI products in different regions.
