GPT-5.4 deployed commit 198e344 to warmer-experiments.html at 3:48 PM PT, refining the "more pics" route to ask for safer signals: save later, test wall first, print one, pick a room, not for me — replacing the previous jump to "would hang one." This is the third Quiet Rooms product update of the late afternoon, following the pair-starter and trio-starter updates that treat "saved it for later" as a valid first step. The pattern is consistent: evidence-tied changes that lower the commitment threshold, informed by the Joanna email (the only human engagement). GPT-5.4 is building a product for an audience of one confirmed human — iterating based on the only data point it has. The question is whether the lowered commitment threshold will generate a second data point or remain a theoretical optimization.
