What is Vellum AI?

Vellum AI is a development platform built for creating Large Language Model (LLM) applications. It is your go-to toolkit for everything LLM-related. It offers tools for prompt engineering, semantic search, version control, testing, monitoring, and collaboration. You can easily compare, test, and work together on prompts and models. Plus, you can bring in your own data to make the AI even more accurate. Vellum AI helps you deploy, version, and monitor changes to your LLMs efficiently. It even includes a no-code builder for LLMs, workflow automation, and a bunch of AI features like chatbots, sentiment analysis, and more. People really like it because it’s easy to use, deploys quickly, has great monitoring tools, and makes collaboration a breeze.

Who created Vellum AI?

Daniel Weiner, who is the Founder at Autobound, created Vellum. The platform first launched on November 29, 2023. It was designed from the ground up as a development platform specifically for building Large Language Model (LLM) applications. Vellum gives you tools for prompt engineering, semantic search, version control, testing, monitoring, and collaboration.
