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

• 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).

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