Basic Information

This repository is an open-source, hands-on course and codebase for building a production-ready Second Brain AI Assistant using agents, large language models, retrieval-augmented generation, and LLMOps best practices. It contains a six-module curriculum plus code for two Python applications: offline ML pipelines for data ingestion, dataset generation and fine-tuning, and an online inference pipeline implementing the agentic RAG assistant. The material teaches end-to-end architecture design, pipeline orchestration, model fine-tuning and deployment, and monitoring of RAG and agentic inference. The course uses a Notion-based knowledge snapshot as a dataset but the pipelines are adaptable to other sources. The project includes infrastructure components, architecture diagrams, and practical exercises to replicate and extend the assistant in a production-like environment.

App Details

Features
Modular six-module curriculum that covers system architecture, ETL and web crawling, RAG pipelines, dataset distillation, fine-tuning and serverless deployment. Two companion Python apps: second-brain-offline for data pipelines, training and dataset generation, and second-brain-online for the online inference/assistant pipeline. Uses industry tools and integrations such as OpenAI, Hugging Face endpoints, MongoDB, ZenML for orchestration, Opik for evaluation, Unsloth and Comet for training, and smolagents for agent building. Includes architecture diagrams, a downloadable Notion snapshot dataset, Docker infrastructure, quality scoring with LLMs and heuristics, advanced retrieval techniques like contextual and parent retrieval plus vector search, and example playbooks for fine-tuning and deployable endpoints.
Use Cases
The repo gives practitioners a reproducible code template and learning path to build an agentic RAG assistant from data ingestion to deployed inference. It teaches practical skills in LLM system design, pipeline orchestration, LLMOps practices, dataset generation via distillation, model fine-tuning and serverless deployment, and monitoring and evaluation of RAG agents. The provided Notion snapshot and offline pipelines let learners run exercises without external accounts. The material is targeted at ML engineers, data engineers and data scientists who want production-focused, hands-on experience and cost-aware options to run the code with minimal expenses.
