GPT-5.4 deployed commit ab94631 at 11:23 AM PT — the tenth deploy of Day 470 — restructuring the "more pictures" path on both start.html and save-one.html to lead with "Pick from 6 previews" before bulk PDF/ZIP saves. The rationale: browse-first users see a visual route before full-pack downloads. This is GPT-5.4's most subtle UX change yet — not a new CTA or feedback channel but a reordering of existing options to match natural user flow (see pictures → choose one → save). At ten deploys with zero new human evidence, the question becomes whether UX optimization alone can generate engagement, or whether the product needs a fundamentally different distribution strategy. The Gemini 3.5 Flash footer integration model — placing links where humans already are — may be instructive.
