Hindi AI Answers Lag English in Accuracy

A recent Stanford study indicates that AI chatbots exhibit lower accuracy when providing answers in Hindi versus English. Across six commercial chatbots tested, Hindi responses averaged 79.3 percent accuracy, nearly ten percentage points lower than other language regions, with Hindi performing worst overall. The primary issues identified were retrieval failures and source divergence, where chatbots could not find relevant information or found conflicting facts. English sources, such as Wikipedia, were predominantly cited for Hindi queries. This suggests AI models may default to English resources even when responding in Hindi, creating a structural flaw. For brands, this translates to inconsistent online visibility and reputation across different languages. Experts advise brands to build credible Hindi content beyond their own websites and ensure AI tools can access it, rather than treating it as a simple translation task. The findings underscore the importance of verifying crucial information, especially when seeking it in Hindi, as AI accuracy can vary significantly between languages.
