The Birth of a Movement

In the span of just twelve months, vibe coding went from being a casual observation in a social media post to becoming the Collins Dictionary Word of the Year 2025. This meteoric rise reflects a fundamental shift in how humans interact with computers and write software.

The story of vibe coding is ultimately the story of how large language models (LLMs) became sophisticated enough that programmers could describe what they wanted in plain English and watch functional code materialize before their eyes. It is a story about surrendering control, embracing uncertainty, and trusting AI to handle the details.

Who Coined the Term Vibe Coding?

Andrej Karpathy coined the term vibe coding on February 2, 2025. In his now-famous post on X (formerly Twitter), Karpathy introduced the concept that would soon captivate the tech world and beyond.

There is 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. It is possible because the LLMs (e.g. Cursor Composer w Sonnet) are getting too good.
— Andrej Karpathy, February 2, 2025

The post quickly went viral, accumulating over 4.5 million views and sparking intense debate across the developer community. Within weeks, the term had spread from social media to mainstream publications including The New York Times, Ars Technica, and The Guardian.

The Original Definition: What Is Vibe Coding?

In his original post, Karpathy provided a detailed description of what vibe coding actually looks like in practice. His characterization painted a picture of a radically new approach to software development.

How Karpathy Described It

  • Talks to Composer with SuperWhisper so he barely touches the keyboard
  • Asks for simple things like “decrease the padding on the sidebar by half”
  • Clicks “Accept All” always — does not read the diffs anymore
  • Copy-pastes error messages with no comment — usually that fixes it
  • Code grows beyond his usual comprehension

The Philosophy Behind It

Karpathy's approach represents a fundamental shift in the programmer's role — from code author to creative director.

As he put it: “I am building a project or webapp, but it is not really coding — I just see stuff, say stuff, run stuff, and copy paste stuff, and it mostly works.”

Karpathy was careful to note the limitations, describing vibe coding as “not too bad for throwaway weekend projects”. He acknowledged that sometimes the LLMs cannot fix a bug, so he would “just work around it or ask for random changes until it goes away.”

Who Is Andrej Karpathy?

Understanding who invented vibe coding requires knowing the remarkable career of Andrej Karpathy. His credentials make him uniquely positioned to observe and articulate shifts in how AI changes software development.

2015-2017
OpenAI Co-Founder

Founding member working on deep learning, computer vision, and early GPT research

2017-2022
Tesla AI Director

Led Autopilot computer vision team and self-driving car AI development

2023-2024
Return to OpenAI

Led midtraining and synthetic data generation before departing in 2024

Karpathy's educational contributions are equally impressive. He designed and taught CS 231n at Stanford — the first deep learning class at the university — which grew from 150 students in 2015 to 750 by 2017. His Zero to Hero series and open-source projects like nanoGPT and nanochat have become global educational resources.

In 2024, he launched Eureka Labs, an AI education company, and was named one of TIME Magazine's 100 Most Influential People in AI. His unique perspective bridging research and practical AI application gave weight to his observations about vibe coding.

Why Vibe Coding Resonated

The term vibe coding spread so rapidly because it perfectly captured something developers were already experiencing but struggled to articulate. Karpathy gave a name to a feeling.

The concept resonated because it acknowledged several truths:

1
LLMs had crossed a threshold

AI code generation became good enough that trusting it made practical sense

2
Many developers felt the same way

The post validated what people were already doing but felt guilty about

3
It democratized coding

Non-programmers could now create software by simply describing what they wanted

4
It built on Karpathy's earlier observation

In 2023, he said “the hottest new programming language is English”

How Vibe Coding Has Evolved

Since Karpathy coined the term, vibe coding has evolved from a casual practice into a recognized methodology with its own ecosystem, tools, and best practices.

Enterprise Adoption

According to industry research, 87% of Fortune 500 companies have adopted at least one vibe coding platform, with 90% of Fortune 100 using GitHub Copilot.

Startup Ecosystem

In Y Combinator's Winter 2025 cohort, 25% of startups had codebases that were approximately 95% AI-generated. The barrier to creating functional software has never been lower.

Non-Developer Adoption

Remarkably, 63% of vibe coding users are non-developers, generating UIs (44%), full-stack apps (20%), and personal software (11%). The democratization Karpathy hinted at has materialized.

Gartner forecasts that 60% of new software code will be AI-generated by 2026. Companies report saving between $10,750 and $47,840 annually per developer depending on actual time savings.

Cautions and Considerations

While vibe coding has transformed development, experts note that 45% of AI-generated code contains security vulnerabilities. Production systems still require human review, testing, and security analysis — which is why platforms that generate production-ready, security-conscious code are becoming essential.

What is vibe coding according to Andrej Karpathy?

According to Karpathy, vibe coding is when you fully give in to the vibes, embrace exponentials, and forget that the code even exists. He described talking to AI assistants through voice, accepting all code changes without reading diffs, and simply copy-pasting error messages until they get fixed.

When did vibe coding become popular?

Vibe coding went viral immediately after Karpathy posted about it on February 2, 2025. The post received over 4.5 million views. By March 2025, major publications like The New York Times, Ars Technica, and The Guardian were covering it. In November 2025, Collins Dictionary named it the Word of the Year.

What tools did Karpathy use for vibe coding?

In his original post, Karpathy mentioned using Cursor Composer with Claude Sonnet for code generation, and SuperWhisper for voice input so he barely even touches the keyboard. He would ask for simple things like decrease the padding on the sidebar by half.

Is vibe coding suitable for production code?

Karpathy originally described vibe coding as not too bad for throwaway weekend projects. While adoption has grown significantly (44% of developers use AI coding tools), experts caution that production code requires understanding, testing, and security review. Modern platforms like Natively help bridge this gap by generating production-ready native mobile apps from natural language while maintaining code quality standards.
