Introducing the AI Gateway

The Vercel AI Gateway, now available for alpha testing, aims to streamline the use of AI models by allowing seamless switching between approximately 100 models without the hassle of managing API keys, rate limits, or provider accounts. Built on the AI SDK 5 alpha, the Gateway handles authentication, usage tracking, and plans to integrate billing in the future, offering developers flexibility in navigating the fast-paced AI landscape. It addresses common issues in production AI applications, such as capacity and rate limiting, by enabling load balancing and failover across providers, thus ensuring consistent performance and availability. The AI SDK, which the Gateway builds upon, provides a unified abstraction for AI model APIs across various modalities and is free and open-source. During the alpha phase, usage of the AI Gateway is free with certain rate limits, and future plans include pay-as-you-go pricing and possible support for bring-your-own-key options. Although the Gateway is not yet ready for production use, it is designed to leverage cost savings and performance improvements as model inference costs decrease and providers compete on quality and price.
