Setup

To setup, set required environment variables. We will use OpenAI for our language model, and Tavily for our search provider.

export OPENAI_API_KEY=...
export TAVILY_API_KEY=...

We will also use LangSmith for observability:

export LANGCHAIN_TRACING_V2="true"
export LANGCHAIN_API_KEY=...
export LANGCHAIN_ENDPOINT="https://api.smith.langchain.com"

Next, you'll need Deno installed, and their experimental Jupyter notebook support. Follow the instructions here.
