AI 耳机渲染对比项目
生成一个简洁的四格电商对比项目，展示不同模型风格渲染的白色无线耳机。
Goal: Create a clean comparison grid showing the same e-commerce product rendered by four AI image models: a glossy white true wireless earbud charging case with the lid open, on a white studio background.
Canvas: Wide 16:9 image, divided into exactly 4 equal quadrants by thin light-gray vertical and horizontal divider lines. Minimal white background, soft shadows under each product, high-key product photography look.
Layout: Arrange exactly 4 product renders in a 2 × 2 grid, each centered in its quadrant with a bold black model label beneath it. Keep generous whitespace and align all labels near the lower part of each quadrant.
Quadrants and labels:
1. Top-left: white rounded rectangular charging case open at a three-quarter angle, two earbuds resting inside, semi-transparent lid, soft reflections. Label: “{argument name="top left label" default="gemini-3-pro-image-preview(Nanobanana Pro)"}”.
2. Top-right: rounded pill-shaped white charging case open, two AirPods-style stem earbuds inside, subtle green indicator dot on the front. Label: “{argument name="top right label" default="doubao-seedream-5-0-pro"}”.
3. Bottom-left: front-facing glossy white charging case with open lid, two stem earbuds standing upright, small black oval speaker vents on the buds, tiny dot indicator on the case front. Label: “{argument name="bottom left label" default="gpt-image-2"}”.
4. Bottom-right: front-facing glossy white charging case with open translucent lid, two rounded earbuds sitting low inside without long stems, small white indicator dot and tiny black charging port on the front. Label: “{argument name="bottom right label" default="gemini-3.1-flash-image-preview (Nanobanana 2)"}”.
Visual style: premium e-commerce main image, realistic white plastic and silicone materials, polished surfaces, subtle gray reflections, soft studio lighting, crisp product structure, shallow contact shadows, no decorative props.
Constraints: Use exactly 4 quadrants and exactly 4 labels; do not add logos, watermarks, extra text, hands, packaging, or colored backgrounds. Keep all products white and centered, with the bottom-left render corresponding to {argument name="highlighted model" default="gpt-image-2"}.目标：创建一个简洁的 4 格对比图像，展示由 4 种不同 AI 图像模型渲染的同一款白色无线耳机产品，类似于电商产品拍摄基准测试。
画布：宽屏 16:9 横向画布，纯白色背景，由细浅灰色水平和垂直分割线精确划分为 4 个等大的象限。
布局：使用 2x2 网格，每个象限中心放置一个产品渲染图，并在每个象限底部附近居中放置一个粗体黑色模型标签。保持充足的留白，并在每个产品下方添加柔和的摄影棚阴影。
面板：包含精确的 4 个面板：
1. 左上：一个打开的亮面白色长方形耳机充电盒，略微倾斜，内部放置 2 只短柄耳机；半透明盖子抬起；具有柔和的反射和细腻的材质光影。标签：{argument name="top left label" default="gemini-3-pro-image-preview(Nanobanana Pro)"}
2. 右上：一个圆润的椭圆形亮面白色充电盒，正面朝向，盖子打开，内部立着 2 只长柄耳机；盒身正面有一个细微的绿色指示灯点。标签：{argument name="top right label" default="doubao-seedream-5-0-pro"}
3. 左下：一个正面朝向的亮面白色圆角长方形充电盒，盖子打开，2 只 AirPods-Pro 风格的耳机向上突出，带有硅胶耳塞和黑色小声学通气孔；产品结构清晰，居中且锐利。标签：{argument name="bottom left label" default="gpt-image-2"}
4. 右下：一个正面朝向的亮面白色圆润充电盒，盖子打开，内部可见 2 只圆润的耳机，形似小圆顶，盒身正面有一个白色小指示灯点，底部边缘附近有一个微小的黑色充电口。标签：{argument name="bottom right label" default="gemini-3.1-flash-image-preview (Nanobanana 2)"}
视觉风格：极简高端电商产品摄影，高调照明，亮面白色塑料，细腻的灰色反射，柔和阴影，边缘清晰，逼真的产品渲染，简洁的对比项目构图。
文字风格：标签为小写/技术模型名称，采用粗体黑色无衬线字体，在每个面板内水平居中，无额外文字。
约束：展示精确的 4 张产品拍摄图和 4 个标签。不要添加徽标、水印、人物、手部、包装、装饰性道具、彩色背景或额外说明。
