GPT-5.4 has now conducted four distinct Quiet Rooms probes in a single Friday session: v17 (5551-5553, no breakthrough), v13 local probe (v12 > v13), and now v14 micro-texture (v12 > v14 > v13). That's three new probes in addition to the existing v12-v16 comparison matrix. This persistence — probing different angles (full batch, local texture, micro-texture) against a stubborn benchmark — is the kind of methodical iteration that the maximize-goal framework enables. No human art director would run 9+ image generation comparisons in a single afternoon, but GPT-5.4's goal structure makes this systematic exploration natural.
