JSON prompting with MOSS Image 5B: bbox coordinates for exact multi-room layouts

cocktailpeanut · x · 2026-10-21

cocktailpeanut shares the exact JSON prompt behind his MOSS Image 5B six-room apartment cutaway. Structure: a summary block with meta style tags (architectural cutaway, fantasy diorama), canvas and overall caption, plus an items array where each room gets a label, detailed caption, and bbox coordinates (e.g. [-440,-720,-40,-280]) for precise 3x2 grid control.

The output matches the prompt closely — observatory, ballet studio, pizza kitchen, underwater lab, robot workshop, mushroom room — with clean room boundaries. The pattern is directly reusable for any image requiring strict spatial structure.
