First Output 101: From Chatbot User to Your First Real AI Build
Six lessons, six things you actually make. Start with one API call costing a fraction of a cent, finish with a working tool and a routing rule that keeps your bill boring.
For people who use ChatGPT or Claude in a browser, have never opened a terminal for AI work, and suspect they are paying a subscription for something they could do for pennies. No prior coding experience assumed beyond copying a command and pressing enter.
Course outline
- 1Your first API call, for a fraction of a centGet a key, send one request, and read the exact cost. By the end you will have made an AI call outside a browser and know what it charged you — to six decimal places.11 min · 3 objectives
- 2Turn a real file into a usable answerStop pasting documents into a chat box. Send a file straight from your machine, get structured output back, and learn why the length of what you send is the thing that costs money.12 min · 3 objectives
- 3Run it a hundred times without a surprise billThe moment you loop, you can lose money while you sleep. Build the estimate-first habit, set a hard cap, and run a real batch job with both in place.12 min · 3 objectives
- 4Pick the cheapest model that still passesRun one prompt across four price tiers, score the answers yourself, and turn the result into a routing rule. This is the lesson that saves you the most money.13 min · 3 objectives
- 5Work out whether your $20 seat is worth itNot everyone should move to the API. Do the break-even honestly — including your own time — and get a number you can defend either way.10 min · 3 objectives
- 6Ship a tiny tool you actually usePut lessons 1 to 5 into one 30-line script with a cost ceiling, a cheap default and an escalation path. Finish the course with something on your machine that works.14 min · 3 objectives
Frequently asked
Is this course really for beginners?
Yes. It assumes you have used a chatbot in a browser and nothing else. Every command is shown in full and explained line by line, and the terminal walkthroughs can be stepped through one command at a time.
How much will it cost me to complete?
Well under a dollar at the rates shown, and most of that is lesson 4's model comparison. Set a $5 spend limit in your provider dashboard before lesson 1 and you cannot exceed it.
Are the terminal demos live?
No — they are recorded sessions, and the component says so. The commands are real and the numbers are computed from real catalogue rates, but nothing executes in your browser. Run them yourself to see your own figures.
Will this make me cancel my subscription?
Possibly not. Lesson 5 does the break-even honestly and it usually favours the seat for conversational use. The course is about knowing which of your work belongs on which, not about picking a side.
