What you'll learn

An accurate mental model of LLMs: tokens, embeddings, attention, and the parameters you tune daily
Prompt engineering that works: the 5-part skeleton, few-shot, chain-of-thought, and schema-enforced structured output
Build a production RAG pipeline end to end — chunking, vector search, hybrid retrieval, reranking, and evaluation
Design and ship agents: the tool-calling loop, planning, reflection, verifier tools, and multi-agent systems
Guardrails for real deployments: budgets, sandboxes, human-in-the-loop approval, and prompt-injection defense
Evaluate AI systems like an engineer: assertions, LLM-as-judge, golden sets, and production observability

About this course

A practical, visual course for developers who want to build real AI products. Start with an accurate mental model of how LLMs work, master prompting and structured output, build a production RAG pipeline (chunking, embeddings, hybrid search, reranking, evaluation), and learn to build agents that use tools safely. Ends with a full capstone project that ties every section together. Provider-agnostic — the concepts transfer across every model and API.
