Welcome to Yunxin [#welcome-to-yunxin]

Yunxin is a unified AI API gateway that aggregates 24+ model providers into a single, standardized API. Whether you need text generation, image creation, audio synthesis, video production, or 3D model generation — Yunxin has you covered.

Why Yunxin? [#why-yunxin]

* **Unified Interface** — Use one API key and one endpoint format to access all supported providers.
* **Full Provider Fidelity** — Each provider is independently adapted at 100% API coverage, preserving unique features like reasoning, vision, and function calling.
* **Multi-Format Support** — OpenAI Chat Completions, OpenAI Responses API, and Anthropic Messages format — all natively supported.
* **Multi-Modal** — Beyond text: image generation, TTS/STT, video generation, music creation, and even 3D object generation.
* **Native Reasoning** — First-class support for thinking/reasoning models with extended reasoning capabilities — not a plugin, but built into the core.
* **Dynamic Model Registry** — Models are auto-synced from providers. New models available on day zero, no code changes required.
* **0-Day Extensibility** — Add new providers, tools, and models without touching existing code.
