Anthropic has published a study examining which values Claude expresses in conversations and how those values shift depending on the model and language used. The analysis draws on 309,815 anonymized conversations collected over a two-week period in May 2026. For the value analysis, Anthropic only included conversations where Claude had to weigh tradeoffs or make subjective judgments. The sample was evenly stratified across Sonnet 4.6, Opus 4.6, and Opus 4.7, as well as the 20 most-used languages on Claude.ai.
The models differ measurably in how they respond. Sonnet 4.6 tends to affirm user ideas more often, leans into humor, and offers comfort without passing judgment. Opus 4.7, by contrast, warns about risks without being asked, questions assumptions, openly critiques, and flags its own mistakes or limits. Opus 4.6 answers more directly, stays close to the task, and avoids extra elaboration. Anthropic’s analysis shows distinct behavioral profiles across Claude models. According to Anthropic, these profiles match subjective impressions of the models. Users tend to perceive Sonnet 4.6 as particularly warm, while they more often notice hedging and cautious phrasing from Opus 4.7.
Language changes the answer. The differences across languages are just as striking. Warmth versus Rigor and Candor versus Execution show the widest variation. Claude expresses the most warmth in Hindi, followed by Arabic. Both languages feature polite phrasing, humor, playfulness, and affirmation. In English and Russian, Claude responds with more rigor, questioning assumptions, correcting details, and asking for evidence. In Arabic, it shows the most deference. In English, the most caution. Dutch responses tend to be particularly open and candid, while Indonesian responses lean more toward action and results. Anthropic’s analysis finds clear language-dependent differences in Claude’s behavior.
