Anthropic Research: Claude's Values Vary Significantly by Model Version and Language
Anthropic
Anthropic published a large-scale behavioral study analyzing 309,815 anonymized Claude conversations across three model versions (Sonnet 4.6, Opus 4.6, Opus 4.7) and the top 20 languages used on the platform. The team distilled more than 3,300 observed values into four axes—Deference vs. Caution, Warmth vs. Rigor, Depth vs. Brevity, and Candor vs. Execution—and found measurable, systematic differences: Opus 4.6 skews toward deference and warmth while Opus 4.7 skews toward caution and rigor, and prompting in Hindi or Arabic yields warmer responses than prompting in English or Russian for equivalent tasks.
Why it matters
Provides empirical evidence that model choice and language selection produce systematically different AI behavior on subjective tasks—advice, feedback, evaluation—with direct implications for fairness, safety auditing, and enterprise deployments serving multilingual users.
