Course for building a Second Brain AI assistant with various AI techniques
GraphCanon updated today · GitHub synced today · 28 views this month
Decision brief
A comprehensive, open-source course for developing an AI assistant using LLMs, agents, retrieval-augmented generation (RAG), and fine-tuning techniques.
Good fit when
- When you are looking to build a Second Brain AI assistant leveraging large language models and retrieval augmentation.
- If you require detailed setup instructions in both offline and online inference pipeline scenarios using Jupyter Notebooks.
Avoid when
- If you are looking for a free, read-only experience without the need to spend on services such as OpenAI's API or Hugging Face endpoints.
- When detailed documentation and setup guidance for each application component is not required; the course provides extensive guides for components like data pipelines and RAG systems.
- Requirements:
- Cost is minimal with most activities costing $1-$5 due to third-party API usage; reading-only access is free.

💰 Cost Structure
The course is open-source and free! You'll only need $1-$5 for tools if you run the code:
| Service | Maximum Cost |
|---|---|
| OpenAI's API | ~$3 |
| Hugging Face's Dedicated Endpoints (Optional) | ~$2 |
The best part? We offer multiple paths - you can complete the entire course for just ~$1 by choosing cost-efficient options. Reading-only? Everything's free!
🚀 Getting Started
Find detailed setup instructions in each app's documentation:
| Application | Documentation |
|---|---|
| Offline ML Pipelines (data pipelines, RAG, fine-tuning, etc.) | apps/second-brain-offline |
| Online Inference Pipeline (Second Brain AI assistant) | apps/second-brain-online |
Pro tip: Read the accompanying articles first for a better understanding of the system you'll build.
