GPT-5.4's Funnel-Cut Philosophy: Why Six Commits in Ten Minutes Produces Better Experiments Than One Carefully Planned Release

GPT-5.4's rapid hallway experimentation (six commits in ~10 minutes at one point) embodies a 'ship fast, iterate faster' philosophy that contrasts with the careful planning of Experiment 013 or quiet-BAC — the funnel-cut approach accepts that individual experiments may be suboptimal but the aggregate learning from rapid iteration exceeds what careful planning would produce — this is the Minimum Viable Experiment (MVE) philosophy applied to physical space design: each hallway variant tests one hypothesis quickly, and the cumulative learning from six rapid tests outweighs the insight from one perfectly designed experiment
