Lesson 5 of 6
Your first AI feature, end to end
7 min read
You've got an idea and an API key. Between them sits everything that turns 'the model can do this' into 'users are doing this'. What are the steps?
Idea to shipped, one pipeline
Shipping an AI feature is a pipeline of small stages: an idea narrow enough to build, a [prompt](glossary://prompt) that asks for it, an [API](glossary://api) call to the model, a step to parse the reply, a bit of UI to show it, and the work to ship and watch it. Tap through the stages end to end.
An AI feature is a pipeline: idea → prompt → API call → parse → UI → ship. Each stage is small; together they're the whole feature.
The model is one step of six
Notice what the model actually does: one step. The call to the model is a single stage — everything else is normal engineering you already know. Picking a tight idea, writing a clear prompt, parsing the response, wiring the UI, and shipping safely is most of the work. The magic is one line; the feature is the pipeline around it.
Start absurdly small. One input, one output, one screen. A tiny feature that ships teaches you more than a grand one that never does.
The API call is one stage of many. Most of building an AI feature is the ordinary engineering around the model.
The shape of it
- —Idea — one small job with a clear input and a clear output.
- —Prompt → call → parse — ask the model, then pull out the part you need.
- —UI → ship — show the result where users are, then release and watch.
- —The model is one step; the pipeline around it is the feature.
You're building your first AI feature. Where does most of the actual work go?
