This repository contains two packages with NVIDIA integrations with LangChain:

• langchain-nvidia-ai-endpoints integratesNVIDIA AI Foundation Models and Endpoints.
• langchain-nvidia-trt implements integrations of NVIDIATensorRT models.

See the notebooks in thecookbook directory for examples of usingChatNVIDIA andNVIDIAEmbeddings with LangGraph for agentic RAG and tool-calling agents.

See thestudio directory to test the agentic RAG workflow in LangGraph Studio.

Simply load thestudio directory inLangGraph Studio and click the "Run" button with an input question.

This will run agentic RAG where it first reflects on the question to decide whether to use web search or vectorstore retrieval. It also grades retrieved documents as well as generated answers.
