Braintrust is now available on the Vercel Marketplace, enabling developers to efficiently manage AI applications by incorporating evaluations, monitoring, and benchmarking directly within their workflows. This integration allows users to send AI traces from their Vercel applications to Braintrust with ease, providing comprehensive visibility into AI performance in production. As AI apps advance to production, the need for robust infrastructure to catch regressions and track changes becomes crucial, and Braintrust offers systematic evaluations, real-time observability, and model flexibility to enhance AI engineering. Developers can compare and swap large language model providers without rewriting code and benefit from production-grade scalability with Brainstore, a database designed for AI workloads. The setup process involves installing Braintrust from the Vercel Marketplace, configuring OpenTelemetry, and managing accounts and billing, all within a unified platform that supports the development, scaling, and deployment of modern web and AI applications.
