One API
One API 是一款开源的大语言模型（LLM）API 管理与聚合工具，旨在将多种 AI 大模型服务统一转换为 OpenAI 兼容接口格式。其核心功能包括：支持 OpenAI、Azure、Claude、文心一言、通义千问等国内外主流大模型的接入与转发，提供统一的 API 密钥管理、负载均衡及用量统计，便于开发者在单一接口下灵活切换和调用不同模型服务。
Core Facts
Open-source projects such as LiteLLM and OneAPI also provide similar unified interface layers.
One API is an open-source large model API aggregation and management platform on GitHub that can unify the APIs of multiple large model service providers into a single platform.
One API's backend is written in Go, the frontend uses React, and it compiles into a single executable file while also providing an official Docker image.
Timeline (last 90 days)
Anthropic has its own Messages API format, while intermediary services such as LiteLLM and One API provide format conversion functionality.
