A term barely anyone used before 2025 became a Word of the Year finalist by the end of it. Search interest in "vibe coding" rose roughly 2,400% over the year, and Collins Dictionary named it among the year's defining words — the kind of trajectory that usually means the word has started meaning more than one thing to more than one audience.
Where it started
The original sense, credited to Andrej Karpathy's framing in early 2025, was fairly narrow and mostly positive: coding by describing what you want in natural language and letting an AI agent generate and iterate on the implementation, with the human steering by outcome rather than by writing syntax directly. In that original sense, it described a workflow, not a character flaw.
Where it's drifted
By 2026, the term picked up a second, harsher meaning in common usage: shipping AI-generated code without reading, understanding, or verifying it — prioritizing speed and a working demo over actually knowing what the code does. That's the sense behind most of the "vibe coding is dangerous" headlines, the security incidents making news, and honestly the sense baked into this site's name.
Both meanings are alive at once right now, which is why the same word shows up in an enthusiastic Product Hunt launch post and in a security researcher's warning about production database wipes in the same week. Context does most of the disambiguating — "I vibe-coded a weekend project" reads very differently from "we vibe-coded straight into production."
Why the distinction actually matters
The useful dividing line isn't "did you use AI to write code" — by 2026 that's most people, most of the time. It's whether the speed came with verification attached, or replaced it. Vibe coding in the original, neutral sense is a legitimate way to work. Vibe coding in the sense that ends up on a security incident report is what happens when the second half — understanding and checking what shipped — got skipped entirely.
