Describe an exploded-view product poster in prose and the layer count and callout positions are whatever the model feels like today. This prompt writes the whole poster as JSON instead: what the model receives is the layout spec itself.

• Every field maps to one region of the poster. Swapping the product means editing fields; swapping copy means editing values. The template cost stays near zero.
• Counts are hard numbers. “9 layers”, “8 callouts, three left, five right” — with those locked, labels stop crowding onto one side.
• The {argument} placeholders make it a real template. Some prompt tools render that syntax as form fields, so you fill blanks and hit generate.

Details worth keeping

• The component list goes down to “pancake lenses” and “facial interface cushion” — that granularity is what the model draws; a vague “internal components” renders as mush.
• The original case writes its copy in Japanese (a Japan-market Meta Quest 3 poster), which proves every string in the JSON can be replaced with any language while the structure stays.
• The footer block — headline plus one selling line — is what makes the sheet read as an advertisement; delete it and you get a bare technical diagram.
• The original case was posted by @wory37303852 on X; the prompt here is curated from the open-source repo freestylefly/awesome-gpt-image-2 (MIT license), and the example image is the case’s own. Source material comes from the open community; rights holders can ask us to take it down at any time.
