What is Portkey AI Gateway?
Portkey's AI Gateway is a fast, lightweight open-source gateway that puts hundreds of LLMs behind one API (Portkey cites 250+ LLMs and 1,600+ language, vision, audio and image models). You can integrate a new model in minutes and add reliability without changing app code.
It handles automatic retries and fallbacks, load balancing and conditional routing, guardrails, multimodal requests and agent-framework integrations, and Portkey's MCP Gateway adds enterprise auth and observability for MCP servers. You can self-host the open-source gateway or use Portkey's hosted platform, which adds observability, prompt management and caching; a Gateway 2.0 pre-release is merging Portkey's enterprise gateway into the open-source project.
