A new international study showed that artificial intelligence understands Polish commands more accurately than any other language, with English only in sixth place. The University of Maryland and Microsoft tested 26 languages to see which ones AI systems interpret most effectively.
Researchers found the results unexpected. “English did not perform best,” they wrote. “It ranked sixth in long-text evaluations, while Polish topped the list.” The study analyzed responses from several major AI models, including OpenAI, Google Gemini, Qwen, Llama, and DeepSeek.
Machines Excel in a Language Humans Find Difficult
Polish achieved an average accuracy of 88%, outperforming every other tested language. “Polish turns out to be the most precise for artificial intelligence,” the Polish Patent Office noted. “It may be hard for people to master, but AI understands it perfectly.”
Despite its smaller training dataset, Polish still surpassed English and Chinese, surprising researchers. Chinese, in contrast, placed near the bottom of the ranking.
Languages Ranked by AI Understanding
AI performed best in Polish, followed closely by French and Italian. Spanish and Russian completed the top five. English landed in sixth position, just ahead of Ukrainian, Portuguese, German, and Dutch. Accuracy scores ranged from 88% for Polish to 80% for Dutch.
The study concluded that complexity does not hinder AI comprehension. Paradoxically, one of the world’s hardest human languages has become the one machines grasp most clearly.
