vectara-agentic is an open-source Python library from Vectara, published on GitHub. It helps developers create AI assistants that combine agents with retrieval-augmented generation, so answers are grounded in your own documents.
The library is built around the Vectara platform, which handles search and retrieval behind the scenes. The code itself is free, though you will need a Vectara account for the underlying service. It is aimed at programmers comfortable with Python who want a quicker route to knowledge-based assistants.
