What is Vellum?

Vellum is a development platform for building, evaluating, and deploying AI applications powered by large language models. Its core function is to streamline the process of turning prototypes into reliable, production-ready systems. The platform provides tools for prompt engineering, testing different models and configurations, and monitoring live performance.
Users typically interact with Vellum through a web interface to manage the lifecycle of their AI features. Developers input prompts, test data, and business logic to construct workflows. The system then facilitates running experiments, comparing outputs from various LLMs, and deploying the best-performing version as an API. According to the team behind the official website, this enables the creation of consistent and measurable AI-driven functionality.
