OpenAI models don’t just understand English—they can handle a wide range of languages, enabling you to build applications that speak to users worldwide. Whether you’re generating text, summarizing content, or analyzing data, many of our models are capable of producing high-quality results in multiple languages.
While the OpenAI Platform interface is currently only available in English, you can freely send prompts in the language you want to use. Our models are optimized for English, but they’re trained on multilingual data, allowing them to understand and generate text across a variety of languages.
For example:
Write your prompt in Spanish, and you’re likely to receive a response in Spanish.
Provide a question in French, and the model will usually reply in French.
Mix languages in your input, and the model can often keep up with the context.
This flexibility means you can:
Localize your application without a separate translation layer.
Analyze multilingual datasets directly in the API.
Prototype global features quickly, without language-specific infrastructure.
For the best results, keep your entire prompt in one language whenever possible. This helps the model stay consistent in its responses.
