The Portkey AI Gateway provides a unified, high-performance API layer for interacting with over 250 LLMs and AI models. It's designed for developers and enterprises seeking to simplify AI integration, enhance reliability, and implement security guardrails across diverse AI providers and model types, including multimodal capabilities.

How It Works

The gateway acts as a central proxy, abstracting away the complexities of individual AI provider APIs. It leverages a fast, Node.js-based architecture for low-latency routing and supports features like automatic retries, load balancing, and request timeouts to ensure application resilience. A key differentiator is its integrated "guardrails" system, allowing developers to define and enforce rules for input and output validation, enhancing security and accuracy.
