The confirmed fact
Collins Dictionary named vibe coding its Word of the Year for 2025.
Collins describes the phrase as an emerging form of software development in which natural language is turned into computer code using AI. Its Word of the Year page credits Andrej Karpathy with popularizing the term and references his description of being able to “forget that the code even exists.”
That is the authoritative core of the story.
Where the phrase came from
Karpathy introduced the phrase in a February 2025 post describing an unusually AI-dependent way of making software. Instead of manually implementing each change, he described telling an AI system what he wanted, accepting generated changes, feeding errors back into it, and steering by the behavior of the result.
The phrase spread beyond that narrow original workflow. “Vibe coding” is now often used more broadly for AI-first software development: prompting tools and agents to create, change, test, or debug software with natural language playing a much larger role than before.
Why a dictionary selection matters
A Word of the Year selection is useful evidence that a phrase became culturally visible enough for a major dictionary publisher to highlight it.
It does not mean Collins has certified vibe coding as a safe software-engineering method, proven its economic impact, or endorsed every claim made about the ecosystem.
That distinction matters because earlier versions of this article made the recognition carry too much weight.
The selection supports a language claim: the phrase became notable and widely used. It does not by itself prove claims about venture investment, user counts, security, or how many non-technical people are building production software.
What Collins actually defines
Collins' public Word of the Year material describes vibe coding in terms of using AI prompted by natural language to assist with writing computer code.
That definition is broader and more cautious than the most extreme version of the original practice. It does not require the builder to ignore the code completely, and it does not tie the practice to a specific tool.
That is useful because the tool landscape keeps changing.
In 2026, AI-first software work can happen through prompt-to-app platforms, AI editors, browser development environments, terminal agents, cloud coding agents, or GitHub-native workflows. The phrase survives even when the specific products change.
What changed between 2025 and 2026
The software-building market moved quickly after the phrase became mainstream.
- ◆Cursor expanded into agentic software work and was acquired by SpaceX in 2026.
- ◆Replit announced a $9 billion valuation in March 2026.
- ◆Lovable continued reporting rapid growth around natural-language application creation.
- ◆OpenAI Codex, Anthropic's Claude Code, GitHub Copilot, and Cognition's Devin ecosystem made coding agents a normal part of the conversation.
Those developments are separate facts from the Collins award. They help explain why the phrase remained relevant, but they should be sourced independently rather than bundled into the dictionary claim.
The criticism is part of the definition's history
“Vibe coding” has always carried some tension.
For some builders it represents leverage: less time on boilerplate, faster iteration, and more people able to create software.
For critics it can describe a risky mode of development where the human accepts generated code without understanding security, architecture, or failure modes.
Both readings can be true depending on how the workflow is practiced.
A production system still needs deliberate review of authorization, data handling, tests, reliability, privacy, and maintainability. The fact that AI wrote the code does not lower the standard the software needs to meet.
What the recognition means for builders
The most useful takeaway is simple: by the end of 2025, “vibe coding” had become recognizable enough to move from a niche technical joke into mainstream language coverage.
Builders no longer need to pretend AI-assisted creation is a fringe behavior. But the phrase should be used precisely enough that readers understand whether you mean:
- ◆casual prompt-driven experimentation,
- ◆disciplined AI-assisted engineering,
- ◆autonomous coding agents,
- ◆or the broader culture of people building software with natural language.
Those are related, but not identical.
