The course guides learners through architecting and implementing a complete LLM system from data collection to production deployment. Students build an AI character that learns to replicate someone’s writing style by training on their digital content from platforms like Medium, Substack, and GitHub. The architecture comprises 4 Python microservices using technologies such as Qdrant for vector storage, Comet ML for experiment tracking, Bytewax for data pipelines, and Pulumi for infrastructure-as-code.
