面向真实图像 API 工作流构建
账户级执行
用户登录后提交任务，并通过现有 SdanceAI 生成流程消耗积分。
输入图片处理
Image to Image 接收源图片 URL，团队可以保留自己的素材管线，再生成新的版本。
按分辨率控制成本
先用 1K 快速迭代，确认提示词和视觉方向后，再切换到 2K 或 4K 生成最终素材。
GPT Image 2 API 常见问题
GPT Image 2 API 最适合什么场景？
它适合提示词图像生成和参考图编辑，包括商品图、广告图、社媒素材、海报和设计稿。
Text to Image 和 Image to Image 有什么区别？
Text to Image 只从提示词开始生成。Image to Image 使用一张或多张源图 URL 加提示词，更适合编辑、变体和保留参考关系的工作流。
支持哪些分辨率？
当前 API 配置包含 1K、2K 和 4K 价格档位。低分辨率适合迭代，高分辨率适合最终素材。
支持哪些画面比例？
可用比例包括 auto、1:1、9:16、16:9、4:3 和 3:4。建议在最终生成前按目标渠道选择比例。
Image to Image 可以使用多少张输入图？
当前图生图 payload 支持输入图片 URL 数组，最多 16 张源图。
接入前在哪里测试？
可以直接使用本页 Playground 测试提示词、输入图片 URL、比例、分辨率和 API payload。
GPT Image 2 API 可以用于商业工作流吗？
本页面面向生产图像工作流配置。商业使用前，请确认账户套餐、积分余额、模型可用性以及适用的内容政策要求。
API 支持回调吗？
支持。请求 schema 包含可选 callback URL，你的服务可以接收任务完成通知。
如何控制成本？
用 1K 做提示词探索和批量草稿，筛选出满意方向后，再用 2K 或 4K 重新生成最终版本。
可以编辑现有商品照片吗？
可以。使用 Image to Image，传入源图 URL，并在提示词中明确需要调整的背景、光影、构图或风格。
