The AI boom is being driven by two languages: English and Mandarin Chinese. The leading AI developers—OpenAI, Anthropic, DeepSeek, Moonshot AI, Z.ai, and others—are almost all based in either the U.S. or mainland China, and so their models perform best in their native tongues.
That leaves countless other languages and dialects, even those spoken by tens of millions of people, by the wayside.
