Vectara-agentic is an Agentic Retrieval-Augmented Generation (RAG) package that enables developers to create AI assistants and agents using Vectara. The integration of Arize Phoenix, a leading open-source observability tool, into vectara-agentic allows users to gain insights into the operation of their AI assistants. This combination provides an easy way to develop Agentic RAG applications with added observability capabilities for better understanding and control over the agent's behavior.
