🦜️🔗 LangChain 🤝 Streamlit agent examples

This repository contains reference implementations of various LangChain agents as Streamlit apps including:

basic_streaming.py: How to do streaming with a simple app using langchain.chat_models.ChatOpenAI
mrkl_demo.py: An agent that replicates the MRKL demo
minimal_agent.py: A minimal agent with search (requires setting OPENAI_API_KEY env to run)
search_and_chat.py: A search-enabled chatbot that remembers chat history

Apps feature LangChain 🤝 Streamlit integrations such as the Callback integration.

Setup

This project uses Poetry for dependency management.

$ poetry install

# Install git pre-commit hooks

We plan to add more agent examples over time - PRs welcome
