這個模型是 T2I 模型,設計用於多面板或多宮格海報、帶文案的概念設計、系列 KV 和社交媒體資產等場景。
默認輸出為 2048×2048 (2K),你也可以自行調整尺寸。它非常適合網格佈局、標題和副標題的空白區域,以及提高文本可讀性。
使用時,請在提示詞中指定主題、佈局(如 2×2 網格或三聯畫)、文本放置(標題、副標題、CTA)和首選樣式。這樣模型就能更準確地生成你想要的內容。
下面是一些提示詞模板和示例。歡迎自由試驗!
提示詞模板

bytedance/seedream-v4/edit
編輯是一個 I2I(圖像到圖像)模型,設計用於對現有圖像進行修改。例如,它可以交換服裝和配飾、調整髮型和化妝、修改產品顏色、材質和圖案,以及更換地板、牆壁和傢俱的室內飾面。
它支援局部編輯和強度控制,讓你在保持主體和光照一致的同時快速創建多個變體。
同樣,i2i 模型在你從一開始就清楚地指定目標時表現更好。下面是一些你可以直接使用的示例和公式!
提示詞模板
1. 肖像
portrait KV series, {STYLE} style, consistent color grading {BRAND_COLOR}, fixed camera look (85mm shallow depth), interchangeable persona: {PERSONA}, reserved lower-third text "{NAME} — {ROLE}"
2. 更改衣服/珠寶/化妝
Outfit swap for portrait, replace clothing with {OUTFIT_DESC}; keep pose and composition; accessories {JEWELRY_DESC}; makeup/hair {MAKEUP_HAIR}; preserve skin tone and lighting; clean edges, no artifacts
3. 背景替換
Background replacement for subject, keep subject edges; new environment: {SCENE_DESC}; match light direction and color temperature; soft contact shadows; no haloing
4. 室內和室外替換
Interior finish swap, update wall {WALL_MATERIAL}, floor {FLOOR_MATERIAL}, furniture upholstery {FABRIC}; layout and lighting unchanged; realistic PBR textures

bytedance/seedream-v4/sequential
Sequential 模型是用於批量圖像生成的 Seedream 變體。它根據你的提示詞一次生成多張圖像,非常適合大規模創作。
但請注意:在提示詞中清楚地指定要生成的圖像數量,並將 max_images 設置為相同的數字。否則,系統將根據 max_images 收費——即使實際上只生成了一張圖像。
使用指南
多張生成:
- 提示詞:
Generate four images of …/Generate a set of images of … - max_image = 4
單張生成:
- 提示詞:
Generate an image of … - max_image = 1
提示詞模板
1. 廣告創意
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. 角色設計(多個姿勢/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. 步驟圖(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.

如果 bytedance/seedream-v4/sequential 幫助你從 0 到 1 開始你的設計,那麼處理多圖輸入和批量輸出的能力會提供更大的助力!
使用 bytedance/seedream-v4/edit-sequential,你可以一次提供多張參考圖像、執行多圖融合、改變樣式和構圖、同時生成多個版本,並快速進行 A/B 對比。
無論是系列 KV、海報資產,還是探索產品顏色、材質和圖案,你都可以在保持一致性的同時高效迭代——使其成為你工作流程中的寶貴工具。
同樣,在生成過程中,注意你的提示詞和 max_images 之間的關係,以避免不必要的成本。
讓我們看一些示例。
