What are you trying to do?
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.
Start the AI Infrastructure path AppliedI 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.
Start the Build AI Agents path CraftI 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.
Start the Master Prompting path AppliedI 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.
Start the Automate Work path CraftI 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.
