AI pair programming vs Vibe coding

Why they differ

Both hand the typing to AI, but in pair programming the developer reads and understands every change, while vibe coding skips that reading on purpose.

AI pair programming

AI-assisted coding

Writing code together with an AI tool in a running back-and-forth, where the human stays in charge and checks every change.

Formal

A way of working, named after the practice of two programmers sharing one screen, in which a developer and an AI coding assistant take turns proposing, questioning and refining code, with the developer reading and approving each change before it is kept.

In plain English

Like driving with a quick-thinking friend reading the map - they suggest turns and spot signs, but your hands stay on the wheel and you decide where to go.

In practice

A developer at an accounting firm, chasing a rounding error in invoice totals, asks the assistant for two possible fixes, picks one, then has it explain a line she does not trust before keeping the change.

Why it matters

Keeping a person reading along is what separates helpful speed from blind trust - the human catches the confident mistakes before they reach real users.

Vibe coding

AI-assisted coding

Building software by describing what you want to an AI and accepting the code it writes without reading it.

Formal

A style of programming, named by a well-known AI researcher in February 2025, in which a person steers an AI coding assistant or coding agent only through requests and by trying the running result, accepting all changes without reviewing or understanding the code itself.

In plain English

Like having a builder put up a shed while you only glance at it from the kitchen window - if it looks fine and the door opens, you move in, never checking what holds up the roof.

In practice

The owner of a small Danish bike repair shop, with no programming background, asks an AI for a booking website, pastes in each error message until it runs, and puts it online the same evening.

Why it matters

It lets almost anyone build a working first version fast, but nobody knows what the code really does - so missing checks, exposed secrets and unsafe packages go live unnoticed.
