What Is Vibe Coding (And Why You Already Know How to Do It)

Andrej Karpathy called it "fully giving in to the vibes." Collins Dictionary made it Word of the Year. What vibe coding actually means, when it works, and how everything you've learned so far has been building toward it.

In February 2025, AI researcher Andrej Karpathy posted something that stuck:

"There's a new kind of coding I call 'vibe coding', where you fully give in to the vibes, embrace exponentials, and forget that the code even exists."

He was describing what happens when you use AI to build software by talking to it instead of typing code. You describe what you want. The AI writes the code. You look at the result and say "change this" or "looks good." Repeat until done.

By the end of 2025, Collins Dictionary named "vibe coding" its Word of the Year. Not bad for a concept that started as one post on X.

But if you've been following this guide, you've already been doing something very close to vibe coding. You just didn't have the buzzword for it.
