AI Earbuds Render Comparison Grid

Goal: Create a clean 4-panel comparison image showing the same white wireless earbuds product rendered by four different AI image models, like an e-commerce product-shot benchmark.

Canvas: Wide 16:9 landscape canvas, pure white background, divided into exactly 4 equal quadrants by thin light-gray horizontal and vertical divider lines.

Layout: Use a 2 by 2 grid with one product render centered in each quadrant and a bold black model label centered near the bottom of each quadrant. Keep generous white space and soft studio shadows under each product.

Panels: Include exactly 4 panels:
1. Top-left: an open glossy white rectangular earbuds charging case, slightly angled, with exactly 2 short-stem earbuds seated inside; translucent lid raised; soft reflections and detailed material lighting. Label: {argument name="top left label" default="gemini-3-pro-image-preview(Nanobanana Pro)"}
2. Top-right: a rounded oval glossy white charging case, front-facing, lid open, with exactly 2 long-stem earbuds standing inside; subtle green indicator dot on the front of the case. Label: {argument name="top right label" default="doubao-seedream-5-0-pro"}
3. Bottom-left: a front-facing glossy white rounded-rectangle charging case with lid open, exactly 2 AirPods-Pro-style earbuds protruding upward with silicone tips and small black acoustic vents; clear product structure, centered and sharp. Label: {argument name="bottom left label" default="gpt-image-2"}
4. Bottom-right: a front-facing glossy white rounded charging case with lid open, exactly 2 rounded earbuds visible like small domes inside, a small white indicator dot on the front, and a tiny black charging port near the bottom edge. Label: {argument name="bottom right label" default="gemini-3.1-flash-image-preview (Nanobanana 2)"}

Visual style: Minimal premium e-commerce product photography, high-key lighting, glossy white plastic, subtle gray reflections, soft shadows, crisp edges, realistic product rendering, clean comparison-board composition.

Text style: Labels are lowercase/technical model names in bold black sans-serif, horizontally centered in each panel, no extra text.

Constraints: Show exactly 4 product shots and exactly 4 labels. Do not add logos, watermarks, people, hands, packaging, decorative props, colored backgrounds, or additional captions.
