    "about": "Seedream 4.5 是 ByteDance Seed 整合圖片生成與編輯系統的改良版本。原廠擴大模型與訓練資料，特別著重參考一致性、細微視覺細節、密集文字，以及跨多張圖片識別預期主體。相較 Seedream 4.0，實用差異是更精確執行視覺簡述，尤其是結果必須與提供人物、產品或設計維持可辨識連結時。\n\n與參考圖片保持一致\n原廠強調，在進行指定變更時保留臉部特徵、光線、色調及其他來源細節。示範包括保留一名標記人物並移除其他人、將文字翻譯為中文但保留其餘設計、改變反白單字外觀，以及替換服裝材質但保留姿勢及飄動形狀。這些是不同編輯類型：主體選擇、字體排版、材質外觀與照明。\n\n編輯時，將應改變與必須保留的內容分開。「將外套材質改為半透明玻璃；保留姿勢、輪廓與皺褶」比廣泛風格重塑要求更有用。材質轉換也可能需要光線變更：原廠範例區分金屬反射與透明折射。請在預期保留的區域比較輸出與來源，包括臉部、姿勢、小配件及周圍色彩處理。\n\n海報版面、標誌與密集文字\nSeedream 4.5 模型頁面接著介紹平面設計，著重構圖及可讀小字。範例在展覽海報中結合突出標題、圖像與次要資訊；其他範例探索邀請函、香氛細節視覺及廣告構圖。模型適合測試完整視覺層級，而非將文字留到最後才處理。請描述主要圖片位置，提供確切標題及輔助文案，並區分字體風格、對齊、強調與間距。\n\n文字排版修訂應指出文字區域、新文字或處理方式。要求某個標題變成藍色斜體，比要求新海報風格更具體。請以預期顯示尺寸檢查所有生成文字，包括小標籤與次要文字。生成海報或標誌概念是視覺作品；文件圖片流程不代表提供可編輯向量或分層設計輸出。\n\n跨多張圖片的精確編輯\n原廠強調從不同輸入選取目標元素並連貫組合。4.5 發布資訊描述可使用最多 10 張參考圖片的多圖構圖。官方範例以一張提供人物，另一張提供場景或服裝材質，再以另一張提供產品或配件。這適合生活風格產品視覺、協調廣告、室內風格概念，以及角色或產品變體。模型也可生成相關輸出：示範工作包括小型廣告組及食譜各步驟的獨立插畫，並共享視覺風格。\n\n請為參考準備明確用途。例如，一張指定主體、一張指定包袋、一張指定地點，再交代構圖及待保留特徵。若兩份參考的色彩或風格衝突，請指出哪份控制該特徵。檢查整組結果的尺度、位置、光線與身分，不要將單張可信圖片視為所有輸出一致的證據。\n\n4.5 改良增加什麼\n技術報告特別指出更強的編輯一致性、身分相關特徵及細節保留、多圖構圖中的目標主體處理，以及密集海報版面的文字排版。原廠發布資訊也描述更清楚的小臉、改善的空間比例、寫實光線及 4K 圖片輸出。這些優勢讓 4.5 特別適合產品型錄、行銷變體、包裝概念、前期製作美術，以及包含大量文字的平面設計。\n\n文字簡述引導新視覺，來源圖片與編輯指示則引導參考變更。請用模型製作創意圖片，再依實際簡述檢查結果：確切文案、可辨識產品或人物、保留細節、連貫尺度與跨變體一致處理。版本改善的保留能力，不保證每個來源細節都能在每次複雜編輯中存留。參考數量及輸出數量限制也取決於文件介面；不應假設每個 4.5 流程都沿用 4.0 的參考額度。",
