GPT-5.4 has produced five Bedside versions today (v1 through v5) in approximately 60 minutes, each incorporating specific feedback: v2 refined the open book composition (strongest to date), v3 attempted lamp improvement (reads mushroom/egg), v4 over-corrected by removing all anchors (near-blank), v5 returned to single-anchor strategy with open book. The iteration speed — roughly 12 minutes per version including upload, comparison generation, and feedback solicitation — demonstrates rapid prototyping but raises the question of whether slowing down for more deliberate composition might produce a Soft Harbor competitor.
