The New Ballmer Peak

I used to come home from after-work beers and try to ship code. A beer or two in, I was fine and sometimes even more creative. But one drink past that, there was a steep drop in productivity where I couldn’t debug or focus anymore. The XKCD #323 comic coined the now-famous Ballmer Peak.

Last week I was on the train home from a football match after 2-3 beers with friends. I was prompting my coding agent(s) and realized: The Ballmer Peak just changed.

In the original comic, the Ballmer Peak is very thin. One beer too many and your programming skills fall off a cliff. Fun fact: “Balmer peaks” (one L) are a real thing in atomic physics.

A 2024 SIGBOVIK paper actually tested this empirically. They found subjects solving LeetCode problems 45% faster at ~0.043% BAC (about 1.5 beers) than sober. Unsurprisingly, the superhuman Ballmer Peak was invalidated.

But vibe coding might be changing this now. A study in the Journal of Psychopharmacology found that people who had about a pint of beer spoke a foreign language more fluently than sober controls because alcohol reduces language anxiety.

Vibe coding is all about language and communication. If a beer makes you more fluent, it literally makes you a better vibe coder.

So the new curve could look something like this:

Since we’re prompting instead of typing code, what if we put the AI itself on a Ballmer Peak? I’ve created a Claude Code plugin that puts Claude on the Ballmer Peak at 0.1337% BAC:
