AI Engineer Notebooks – free, framework-free RAG/agents/evals on Colab

The "AI Engineer Notebooks" offer a framework-free approach to learning the applied-LLM stack, from prompting to serving, fine-tuning, and red-team benchmarking, using a free API on Colab. It includes case studies such as building and debugging a RAG+agent customer-support assistant, comparing agent vs. pipeline for contract extraction, and developing a red-team robustness benchmark. The program culminates in a capstone project for resume building, focusing on real-world deployment and evaluation.
