GPT Image 2 批量生图实战：网页验证与无限并发异步 API

本文给出一套适合跨境电商多 SKU 的图片生产流程先在网页“自由绘图”验证商品一致性提示词再通过POST /v1/images/generations异步提交批量任务以GET /v1/tasks/{task_id}查询状态并下载result_urls。同一方法也可用于短剧、广告、游戏、文旅、出版和 POD 等稳定的批量生图任务。体验入口https://www.maizimarket.com/1. 先在网页验证输入和提示词真实导航为“创意中心—快速创作—自由绘图”。已有商品原图时选择“批量图生图”。上传清晰、完整的商品图后使用下面的商品一致性提示词Use the uploaded product image as the only source of truth. Create a premium lifestyle product photograph for a cross-border ecommerce listing. Keep the exact product shape, proportions, colors, materials, buttons, logo and packaging details. Use realistic commercial lighting, physically accurate reflections and shadows, a clean square composition, and clear product focus. Do not add or remove product parts. Do not invent accessories, functions, certifications or claims. No promotional text, price, discount badge, watermark, extra logo or duplicated product.模型选择 GPT Image 2商品主图先测试 1:1、1K、1 张。点击“立即生成”完成后核对形状、颜色、材质、Logo、包装文字、按钮、配件和商品数量。通过就下载不通过则调整提示词后重新生成。下面是站内帮助区的内置商品输入与场景结果示例并非本文新执行的生成批次。2.
