What are you trying to do?

Foundations

I want to understand how AI systems work under the hood

The plumbing behind every AI feature: how text becomes tokens and vectors, and how models are grounded in real data.

⏱ ~35 min·7 steps

Start the AI Infrastructure path Applied

I want to build an AI agent that takes actions

From a model that can only talk to a system that can act: tools, structured calls, patterns, memory, and how to architect it.

⏱ ~55 min·13 steps

Start the Build AI Agents path Craft

I want to get great answers out of AI

Write prompts that behave: see what they leave to chance, build them up, x-ray the anatomy, catch the smells, compare versions, study good vs bad, then put it all together in the Prompt Optimizer.

⏱ ~30 min·7 steps

Start the Master Prompting path Applied

I want to automate work with AI

From manual busywork to systems that run themselves: the trigger-to-action model, the agents-vs-workflows-vs-RPA map, how automations fire, and how AI orchestrates the steps.

⏱ ~40 min·10 steps

Start the Automate Work path Craft

I want to write real code with AI instead of fighting it

The method behind getting great code out of AI: the right mental model, the training cutoff, managing context, planning then dictating, and the prompt that ties it together. Build a real coding prompt as you go.

⏱ ~35 min·5 steps

Start the Coding with AI path Career

I want to land a job building with AI

The free version of what a bootcamp charges five figures for: build real proof, refresh the concepts a screen will probe, and learn to present your work well. No job promised, just the parts you control.
