How AI like ChatGPT actually works
⏱ 25 min read · 📖 8 topics
This is your very first GenAI class.
How to actually talk to an AI so it does what you want

In Session 1 we learned how an LLM works on the inside.
Giving the AI hands: from chatbot to agent
⏱ 23 min read · 📖 7 topics
In Session 1 you learned that an LLM is just a next-token predictor that lives in a frozen brain with no memory and a knowledge cutoff.
Giving an AI an open book: how RAG works
⏱ 23 min read · 📖 7 topics
In Session 1 you learned that an LLM only knows what it absorbed during training — so it has a knowledge cutoff , can't see your private files, and…
Making RAG actually good
⏱ 27 min read · 📖 8 topics
Last time (Session 4) you built a basic RAG system: store documents, find the relevant ones, and feed them to the model.
Building real apps: LangChain & LangGraph
⏱ 24 min read · 📖 8 topics
So far you've learned what a model is (Session 1), how to talk to it well (Session 2), how to give it tools and turn it into an agent (Session 3),…
Building agents the easy way: the Agent SDK
⏱ 22 min read · 📖 7 topics
In Session 6 you wired up agents by hand with LangChain and LangGraph — drawing every node and edge yourself.
Threads & Tracing — keeping memory of, and watching, your agent
⏱ 22 min read · 📖 5 topics
In Session 7 you built your first agent with the Agent SDK.
How AI agents remember things

Teaching AI to remember connections, not just facts
⏱ 17 min read · 📖 4 topics
In Session 9 we gave our agent a memory; in Sessions 4–5 we taught it to search documents with vectors.
Talking to AI out loud — how voice agents work
⏱ 20 min read · 📖 5 topics
You've already met the AI "brain" (the LLM from Session 1) and seen how it can act as an agent that uses tools (Sessions 3 & 7).
How AI agents plug into tools and talk to each other
⏱ 24 min read · 📖 8 topics
In earlier sessions you taught a single agent to call tools and hand work to other agents.
