One Prompt, Ten Results

One prompt, ten results: the bedroom pop stress test

We ran June Okafor's bedroom pop recipe ten times without changing a word, rated every take in the open, and learned where the dice actually land.

The most common question in the lab inbox: if I run the same prompt twice, what changes? The honest answer is a distribution, not an anecdote. So we ran June Okafor's bedroom pop recipe ten consecutive times on the same model build, same day, and rated each take on our five dimensions before comparing notes.

Small Hours

96 BPM · G maj · 4:29

Run 2, the strongest take, later rewritten and re-sung for release as Small Hours.

Publishing the bad takes was the point. Taste is a public act now.

The practical lesson: the recipe's stated reliability of 4 out of 5 held up, but only if 'usable' is your bar. If your bar is 'release candidate', budget five runs per keeper and write your first lyric line yourself. Every run where June supplied a concrete opening image ('the lamp is still on') scored higher on lyric quality than the runs that started blank.
