Notes

• The goal is to provide an introductory understanding of the use cases of LangChain.

• This notebook is based on the LangChain Tutorial (by Greg Kamradt) and the LangChain Documentation.

• The default models (davinci-003 and gpt-3.5-turbo) are used throughout the notebook; gpt-4.0 would surely get better results.

• A paid OPENAI_API_KEY is required to run the code blocks involving LLMs.
