Below worked for me
intext:"vibe coding" before:2025/02/01
The first result I got was this one https://vibecoding.vercel.app/ - which is shown as being from 2023... but that's fake.
Read the page and it starts by saying:
> On November 30, 2023, Andrej Karpathy coined the term "vibecoding"
And then includes a screenshot of Andrej's tweet - this one: https://twitter.com/karpathy/status/1886192184808149383
But that tweet is dated 2nd February 2025. The Vercel-hosted site is lying about the date.
I don't think Google's "before" filter actually works. It looks to me like blog spammers have figured this out and now habitually back-date their posts to a date well before they were written.
Another clue: that article links to this one ("describe what you want ") https://alitu.com/creator/workflow/what-is-vibe-coding/ - which links to Andrej's February tweet as the origin of the term.
It's funny, I tried to search that exact keywords and this exact comment is on the top page
