To ensure your successful deployment, set the following environment variables:
# Get it from https://platform.openai.com/account/api-keys
OPENAI_API_KEY=<YOUR_API_KEY>LangChain framework is intended to develop language model-powered applications that are data-aware, agentic, and differentiated. More information is available on the LangChain website.
