    "about": "Recraft V4.1 Utility Pro 是 Recraft V4.1 中 Utility 分支解析度較高的點陣版本。原廠區分 Utility 直觀的呈現方式，以及主要 V4.1 模型更具表現力的角度、光線與構圖選擇。Utility 偏好簡單場景、均勻打光與正面主體。因此，它適合商品刊登視覺、設計示意圖，以及物件須容易辨識、平靜構圖有助任務的其他工作。\n\n確切模型代碼為 recraftv4_1_utility_pro。原廠參考資料列出細節更精細的 2K 點陣輸出，格式為無損 WebP 或 PNG。尺寸表中正方形為 2048 × 2048 像素，4:3 為 2432 × 1792，其他支援長寬比各有對應尺寸。這與標準 Utility 的 1K 輸出不同。它不會將圖片變成可編輯向量檔，該用途由輸出 SVG 的 Vector 版本提供。\n\n需求開頭先指出物件、材質、觀看角度、背景，以及少數必須可見的細節。商品刊登圖可要求正面陶瓷收納罐置於淺色中性表面、均勻照明、蓋子關閉，並在輪廓周圍留出清楚空間。若場景須保持簡潔，請明確說明，不要依賴 Utility 名稱包含所有呈現選擇。製作一系列刊登圖片時，在更換產品描述的同時，維持取景與背景要求一致。\n\nV4.1 生成參考資料支援最多 10,000 個字元的提示詞、偏好色與背景色控制、隨機種子，以及 1 至 6 張輸出。相容的已儲存風格或選用參考圖片可引導外觀；專門的 V4 Styles 則是風格始終為必要條件的另一條產品線。選用參考圖時，採用視覺方向一致的清楚素材。不保證參考圖色彩精確重現，因此品牌色要求仍須寫入明確需求，並檢查輸出。以參考圖生成風格時，使用 1 至 10 張 PNG、JPG 或 WebP 圖片，總大小不超過 64 MB，每張小於 20 MB。每張參考圖最短邊至少 256 像素，最長邊不超過 4,096 像素，解析度不超過 1,600 萬像素。參考圖與相容的已儲存風格應擇一使用，不能同時使用。以參考圖生成風格時，彈性比對允許較自由的詮釋，精確比對則更貼近渲染方式、色盤、構圖與光線。\n\nRecraft 也為 V4.1 系列記載圖生圖，結合現有圖片、提示詞與 0 至 1 的 strength。較低 strength 更接近來源，較高則允許較大變化。當起始構圖或主體應引導新版本時，這項功能很有用。同一轉換操作不接受 V4.1 自訂風格控制項。原廠圖片輸入限制為小於 20 MB、最高 16 MP，邊長介於 256 至 4096 像素。\n\nUtility Pro 同樣受 V4.1 的控制限制，不接受 negative_prompt、精選風格名稱、text_layout、artistic_level 與 no_text。請正向描述預期場景，需要精確文字或版面時，交由合適的後製步驟處理。將產品視覺視為忠實刊登素材前，請檢查所提供材質、形狀與必要細節。實用成果是依清楚產品或示意圖需求準備的較大點陣構圖，確切產品事實則仍以任務提供內容為準。",
