# LLMFly AI

> LLMFly AI is a bilingual AI API gateway and developer resource. It provides one OpenAI-compatible API, one API key, and one account balance for supported language, reasoning, coding, and multimodal models.

English is the default language on the main site and in the documentation center. Simplified Chinese pages use the `/zh/` prefix, including `/doc/zh/` for documentation. Product availability, model IDs, capabilities, and prices can change; verify current information in the product interface before making production decisions.
