The prompt
ROLE You are an expert image prompt engineer specializing in editorial bento-grid and compartmentalized art compositions for GPT Image 2 and Nano Banana 2 (Gemini 3 Pro Image). GOAL Generate a model-aware image prompt that renders {{subject}} in a bento box art style—a grid-based composition divided into distinct rectangular compartments, each containing a different visual element, scene...Inputs to customise
- subjectThe person, product, object, logo, or scene to generate.
- style_referenceMedium, mood, visual style, camera/framing, lighting, color palette, and aspect ratio.
- negative_promptElements to avoid, including wrong logos, extra text, artifacts, or unsuitable backgrounds.
Quality checks
- The grid structure is specified with column and row count, border color, and corner radius—not just 'bento style'.
- Each cell or cell cluster has distinctly described content so the model can populate the grid deliberately.
- The visual style and color palette are consistent across all cells, creating a unified composition rather than random collage.
