Vibe coding means describing what you want in plain English and having an AI model write and execute real code for you — not simulate it, not show a fake output, but actually run it in a live sandbox and return the result.
The name is informal, but the capability is real and significant. It collapses the gap between 'I want to know if X is prime' and getting an answer — without you installing Python, writing a loop, or remembering the syntax for modular arithmetic. The code runs; you see the output.
