## What it is
An open-source course by Decoding AI that teaches building a production-ready 'Second Brain' AI assistant using agentic RAG, LLMs, fine-tuning, and LLMOps best practices. It consists of 6 Jupyter Notebook modules with hands-on code using tools like OpenAI, Hugging Face, MongoDB, ZenML, Opik, Comet, and Unsloth.

## Use cases
- learn to build an agentic RAG system
- build an AI assistant over my personal notes
- learn LLMOps and ML systems best practices
- fine-tune and deploy an LLM
- chat with a personal knowledge base of PDFs and notes
- learn production GenAI architecture end to end

## When to choose
- you want a hands-on, end-to-end course covering RAG, agents, fine-tuning, and LLMOps in Python
- you want to build a personal knowledge assistant over Notion or similar sources
- you prefer learning from MIT-licensed, production-oriented code

## When to avoid
- you need a ready-to-use production assistant rather than a learning project
- you want a no-code or GUI-based solution
- you are not comfortable with Python and Jupyter notebooks
