Did you look at the branch? This is vibed, even with the most liberal definition

https://github.com/oven-sh/bun/compare/claude/phase-a-port

This single commit is 65k lines of additions

https://github.com/oven-sh/bun/commit/ffa6ce211a0267161ae48b...

The definition is at https://x.com/karpathy/status/1886192184808149383 and no that does not match what is in the branch. Systemically migrating a code base using an LLM does not match the defintion of vibe coding.

There's a decent article by Simon Willison that talks about this: https://simonwillison.net/2025/Mar/19/vibe-coding/

> I’m seeing people apply the term “vibe coding” to all forms of code written with the assistance of AI. I think that both dilutes the term and gives a false impression of what’s possible with responsible AI-assisted programming.

You're right, all 750k lines of code added in a single day - definitely reviewed and completely understood.

		Thanks. That helps us know not to take Wiktionary seriously.

The dilution of the term is a real problem sometimes.

But pointing your AI at an entire codebase to transpile pretty much entirely by itself? Yeah vibe coding is a fitting term.

Even if you wrote it a small essay on how to Rust. That improves the situation but doesn't change the core autonomy/hope of the task.

This is just a coined term; definitions evolve over time based on usage

Then "vibe coding" is a useless term, if it just means "LLM-assisted coding". We might as well just say "LLM-assisted coding" or "AI coding" or whatever.

As much as I find the word "vibe" generally annoying (in all contexts), I actually really like "vibe coding" as "LLM did everything and I didn't even look at it". It's a succinct, useful way to describe that mode of doing things. Diluting it down to "LLM-assisted coding" makes it useless.

All language is "coined terms". The point is that if you dilute the definition of a term, you make the term useless. Evolution of a term isn't done automatically. Correcting terms such as these pushed the evolution in a more useful way. Also, evolution of language is not a magic spell that automatically forgives people on making language mistakes.
