About Portkey

At its core, Portkey is an AI gateway that routes requests across 1,600+ models with fallbacks, load balancing and guardrails. What sets it apart is that it adds observability, prompt management and semantic caching aimed at production reliability. For teams moving agents from prototype to production, that focus on reliability and visibility matters more than adding another layer of fragile automation.
