Getting started

Langchain UI API

We have migrated all agent functionality from LangChain Typescript to LangChain Python. Thus you will need to run the Langchain UI API in order to interact with the chatbot. In the future when the TS package is on par with the Python package we will migrate to only using Javascript.
