Vellum AI: A platform for developing, evaluating, and deploying AI products.

What it does

Vellum AI is a platform designed to help AI product developers take their ideas from early-stage concepts to production-grade features. It provides tooling for experimentation, evaluation, deployment, monitoring, and collaboration, all in one place. Vellum offers features like a visual workflow builder, an SDK, prompt engineering tools, evaluation metrics, retrieval UIs and APIs, one-click deployment, and observability tools to track AI decisions.

How to use: Vellum AI can be used to build AI systems, from basic prompts to agentic workflows, using its Workflows IDE. Users can define, edit, and run code or UI, and push/pull changes between the two. The platform also allows for evaluating AI system quality with pre-made or custom-built metrics and deploying AI updates with easy integration and one-click deploy.
