在前面的文章中，我們已經介紹了 FLUX 文生圖的基本操作，接下來將進一步介紹 FLUX Redux。透過參考圖片與提示詞的結合，讓 AI 不僅能夠「從零生成」，更能夠基於既有圖像進行高品質的重繪與創作。

FLUX Redux 簡介

FLUX Redux 是由 Black Forest Labs 推出的 FLUX 系列延伸模型，主要用於參考圖像重繪（Image Variation）與風格轉換等應用。與傳統的文生圖模型不同，FLUX Redux 能夠根據使用者提供的參考圖片，保留原始構圖、主體特徵或整體氛圍，同時結合新的提示詞（Prompt）重新生成具有不同風格或細節的圖像。

透過 FLUX Redux，使用者可以輕鬆實現照片風格轉換、角色重繪、產品情境圖生成，以及將草圖或概念圖轉換為高品質成品等應用。相較於單純使用文生圖模型，FLUX Redux 在維持原始圖像特徵方面表現更加出色，能夠有效降低角色走樣或構圖偏移的情況。

本篇將介紹如何在 ComfyUI 中安裝 FLUX Redux 所需模型，並透過工作流快速建立以圖片為基礎的 AI 生成流程，讓讀者能夠運用現有圖片作為創作起點，產生更符合需求的高品質圖像作品。
