Overview
Gateway是一个开源的AI网关，专为快速、可靠和安全地路由到1600+语言、视觉、音频和图像模型而设计。作为一个轻量级的企业级解决方案，Gateway每天处理超过100亿个tokens，提供低于1ms的延迟和仅122kb的占用空间。该工具支持250+大语言模型的统一API访问，具备自动重试、故障转移、负载均衡等企业级功能。Gateway不仅是开源项目（11K+ GitHub星标），还提供托管服务和企业部署选项。其核心价值在于简化多模型集成，让开发者可以在2分钟内集成任何语言模型，同时通过内置的可靠性机制防止服务中断。工具正在向2.0版本演进，将Portkey的企业级网关核心合并到开源版本中，为AI应用提供更强大的基础设施支持。
Deep Analysis
vs LiteLLM: production-focused with guardrails, caching, and MCP Gateway; vs OpenRouter: self-hostable with enterprise governance and conditional routing rather than just model access
