AI takes different personalities by language, tests of five models show

A study found that running the same personality test on large language models can yield different results depending on the language used for answers. Researchers tested five AI models with the 60-question Big Five Inventory-2 in English and Chinese, and added French for Le Chat. Models generally rated themselves as agreeable and reliable with low negative emotionality, but scores differed by language. The researchers said the causes were unclear and scores may not reflect real conversation ability.
