LLM Twin Course: Building Your Production-Ready AI Replica

Decoding ML (Decoding AI) · on GitHub

FreeintermediateSelf-paced

An end-to-end LLMOps build pairing written lessons with code: data crawling and change-data-capture, a streaming feature pipeline with advanced RAG, instruction-dataset generation, fine-tuning and evaluation, and a deployed RAG inference service with prompt monitoring. It suits ML and backend engineers who want to see every production component of an LLM system, not just the prompt.

Who it's for

Engineers and ML practitioners. This is an intermediate course in MLOps & AI Engineering, running about 12 lessons (10 core + 2 bonus), self-paced.

Cost at a glance

Free. MIT-licensed and free with no enrollment; running it costs roughly $1 in OpenAI API usage and under $10 on AWS, and the README promotes the paid LLM Engineer's Handbook. Price seen 2026-11-01.
