Seedream V4 Features

功能介绍

Seedream 4.0 支持三种输入类型：文本、单张图像和多张图像。

它提供多图像融合、图像编辑和基于序列的批量生成功能，具有主题一致性，使创作更加灵活且可控。

模型选择

bytedance/seedream-v4

这是一款 T2I 模型，专为多面板或多格海报、带文案的概念设计、系列 KV 和社交媒体资源等场景设计。

默认输出为 2048×2048（2K），你也可以自己调整尺寸。它非常适合网格布局、为标题和副标题预留空白、提高文本可读性。

使用时，请在提示词中指定主题、布局（如 2×2 网格或三联画）、文本位置（标题、副标题、CTA）和偏好风格。这样模型可以更准确地生成你想要的内容。

下面是一些提示词模板和示例。尽管尝试吧！

提示词模板

编辑模型是一款 I2I（图像到图像）模型，用于对现有图像进行修改。例如，它可以更换服装和配饰、调整发型和妆容、修改产品颜色、材质和图案，以及替换地板、墙壁和家具等室内装饰。

它支持本地编辑和强度控制，让你在保持主体和光线一致的同时，快速创建多个变体。

同样，I2I 模型在你从一开始就明确指定目标时表现更好。下面是你可以直接使用的一些示例和公式！

bytedance/seedream-v4/sequential

Sequential 模型是 Seedream 的批量图像生成变体。它根据你的提示词一次生成多张图像，非常适合大规模创作。

但请注意：在提示词中明确指定要生成的图像数量，并将 max_images 设置为相同的数字。否则，系统将根据 max_images 收费——即使实际只创建了一张图像。

使用指南

多张生成：

  • 提示词：Generate four images of … / Generate a set of images of …
  • max_image = 4

单张生成：

  • 提示词：Generate an image of …
  • max_image = 1

提示词模板

1. 广告创意

Generate 4 poster concepts of the same campaign. Image 1: headline "[H1A]", [BG_A]; Image 2: headline "[H1B]", [BG_B]; Image 3: headline "[H1C]", [BG_C]; Image 4: headline "[H1D]", [BG_D]. Keep brand color [BRAND_COLOR], consistent grid and margins, cinematic lighting.

2. 角色设计（多个姿势/表情）

Generate 6 character sheets of [CHARACTER]. Image 1: neutral pose; Image 2: action pose; Image 3: side profile; Image 4: back view; Image 5: happy expression; Image 6: serious expression. Same outfit and palette, clean turnaround style.

3. 步骤图解（1→N）

Generate 3 step-by-step visuals for [PROCESS]. Image 1: step 1 [STEP1]; Image 2: step 2 [STEP2]; Image 3: step 3 [STEP3]. Uniform style and icons, numbered labels.

无论是系列 KV、海报资源，还是探索产品颜色、材质和图案，你都可以高效迭代，同时保持一致性——使其成为你工作流程中的重要部分。

同样，在生成过程中，请注意提示词和 max_images 之间的关系，以避免不必要的成本。
