llm-python
A set of instructional materials, code samples and Python scripts featuring LLMs (GPT etc) through interfaces like llamaindex, LangChain, OpenAI's Agent SDK, Chroma (Chromadb), Pinecone etc.
The code examples are aimed at helping you learn how to build LLM applications and Agents using Python. The code is designed to be self-contained and singularly focused, so you can pick and choose the usage patterns most relevant to your needs.
Many examples have accompanying videos on my YouTube channel.
Learn LangChain from my YouTube channel (~9 hours of LLM hands-on building tutorials); Each lesson is accompanied by the corresponding code in this repo and is designed to be self-contained -- while still focused on some key concepts in LLM (large language model) development and tooling.
