The output is a labelled aerial 3D layout. **The other half is a genuine test rather than a demo** — the reviewer makes a series of small edits specifically to measure drift, because his standing complaint about the previous model is that a face becomes unrecognisable by the third or fourth generation.

It earns a page here for the sketch-plus-description technique and the edit-consistency measurement, both of which generalise to any spatial or layout task you hand a model. - Availability was still rolling out when recorded; if you do not see the updated images tab, you do not have it yet. - The consistency finding comes from one sequence of edits on one image. It is a real observation and a small sample. - Generation timings were measured on the reviewer's account under normal load and will vary. ## Key Takeaways - **The sketch feature lives behind the plus icon** in the images tab, opening a canvas with shape and freehand tools. Access was still rolling out at the time of recording — the updated images-tab icon is the tell. - **Shapes carry spatial intent, text carries meaning.** The working prompt names each shape by colour and says what it represents: white square is floor space, green rectangle is the desk with two monitors, yellow circles are camera positions, purple rectangle is where you sit. - **Generation times, measured:** roughly a minute and a half for the first render, about 1:50 for a subsequent edit. Progress climbs at roughly 1% per second, so the bar is a usable estimate. - **Consistency across edits held.** Flicking between generations, the reviewer finds essentially everything preserved between the original and the edited version — the only visible difference being lighting. That directly addresses the complained-about failure in GPT Image 2, where a subject degraded by the third or fourth generation. - **It is not perfect and he says so:** the generated signage came out sideways, and some details in the render are inventions rather than reproductions of what was drawn. - **Edits are targeted by region.** Marking an area and describing the change ("in that red circle, put a really tall plant") is how small changes are requested, rather than re-prompting the whole image. ## More ChatGPT news [▶ OpenAI's Agents API is a hosted Codex harness — here is what it takes over 2026-09-10](https://openclawdatabase.com/news/videos/2026-09-10-openai-agents-api-hosted-harness/) [▶ Codex Desktop for Business: Setup, Approval Modes and Scheduled Tasks 2026-08-23](https://openclawdatabase.com/news/videos/2026-08-23-codex-desktop-business-setup/) [▶ Docker's Agent Sandbox Runtime: Scoped Credentials Per Task, Local to Cloud 2026-08-20](https://openclawdatabase.com/news/videos/2026-08-20-docker-agent-sandbox-runtime/) [▶ Codex browser and computer use: saving flows as skills you can schedule 2026-08-13](https://openclawdatabase.com/news/videos/2026-08-13-codex-browser-computer-use-skills/) [▶ Same prompt, three harnesses: a Claude vs Grok vs Codex writing test (hands-on comparison, not a how-to) 2026-08-13](https://openclawdatabase.com/news/videos/2026-08-13-claude-grok-codex-writing-test/) [▶ Progressive context shaping: steering agent runs that last ten hours 2026-08-12](https://openclawdatabase.com/news/videos/2026-08-12-progressive-context-shaping-long-agent-runs/) [See all ChatGPT news →](https://openclawdatabase.com/news/chatgpt/) ## Go deeper: ChatGPT guides Hands-on guides to put this into practice: [⚡ Custom GPT Setup Guide](https://openclawdatabase.com/chatgpt/setup/) [🤖 Custom GPTs Deep Dive](https://openclawdatabase.com/chatgpt/custom-gpts/) [🤖 Agent Mode](https://openclawdatabase.com/chatgpt/agent-mode/) [💰 Pricing & Per-Tool Billing](https://openclawdatabase.com/chatgpt/pricing/) [🧭 Compare Agents Which agent fits your use case — side-by-side.](https://openclawdatabase.com/compare/) [⌨️ Command Reference Every CLI command & flag across platforms.](https://openclawdatabase.com/commands/)
