Multilingual AI
AI models capable of understanding and generating text in multiple languages. Modern LLMs often support 50-100+ languages, though performance varies significantly across languages.
Why It Matters
Multilingual capability determines whether AI serves a global audience or only English speakers. Most of the world communicates in non-English languages.
Example
Claude responding fluently in Japanese, translating between Korean and French, and understanding code comments in Hindi — all within a single model.
Think of it like...
Like a polyglot who speaks many languages — they can communicate with people worldwide, though they may be more eloquent in some languages than others.
