There’s 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’s possible because the LLMs (e.g. Cursor Composer w Sonnet) are getting too good. Also I just talk to Composer with SuperWhisper so I barely even touch the keyboard. I ask for the dumbest things like “decrease the padding on the sidebar by half” because I’m too lazy to find it. I “Accept All” always, I don’t read the diffs anymore. When I get error messages I just copy paste them in with no comment, usually that fixes it. The code grows beyond my usual comprehension, I’d have to really read through it for a while. Sometimes the LLMs can’t fix a bug so I just work around it or ask for random changes until it goes away. It’s not too bad for throwaway weekend projects, but still quite amusing. I’m building a project or webapp, but it’s not really coding - I just see stuff, say stuff, run stuff, and copy paste stuff, and it mostly works.<\/p><\/blockquote>\n\n

I’m concerned that the definition is already escaping its original intent. 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<\/a>.<\/p>\n

Vibe coding is not<\/em> the same thing as writing code with the help of LLMs!<\/p>\n

[…]<\/p>\n

Andrej is an extremely talented and experienced programmer—he has no need for AI assistance at all. He’s using LLMs like this because it’s fun to try out wild new ideas, and the speed at which an LLM can produce code is an order of magnitude faster than even the most skilled human programmers. For low stakes projects and prototypes why not just let it rip<\/em>?<\/p>\n

When I talk about vibe coding I mean building software with an LLM without reviewing the code it writes<\/strong>.<\/p>\n<\/blockquote>\n\n

vibe coding, where 2 engineers can now create the tech debt of at least 50 engineers<\/p>\n<\/blockquote>\n\n

But I just want to quickly recommend; do not hire anyone (a person or an agency) that thinks vibe coding is a good idea for production level products.<\/p>

Experimenting? Playing? Thinking through ideas rapidly? Absolutely.<\/p>

Think I’m crazy? Look at this email I just received from “Ian Foster” of Grayphite – a supposed “Cutting-Edge Software & AI solutions” business.<\/p><\/blockquote>\n\n
