It addresses the limitations of monolithic text prompts by breaking down creative elements into distinct, manageable categories, allowing users to build highly specific and reproducible image generation settings.<h3 id="key-features">Key Features</h3><ul><li>Structured Prompting: Organizes prompts into five main categories (Scene, Subject, Photography, Lighting, Style) and fifteen sub-options for clear, hierarchical composition.</li><li>Customizable Options: Automatically generates an <code>z_image_options</code> directory, enabling users to easily modify and expand the prompt choices via simple <code>.txt</code> files.</li><li>Style Templates: Includes built-in style templates (e.g., Cyberpunk, Fantasy Magic, Cinematic Portrait) that can be applied with a single click to accelerate creation.</li><li>Multi-Language Support: Supports output in English, Chinese, or Bilingual format, accommodating various models and user preferences.</li><li>Dual Output Formats:<ul><li><code>json_prompt</code>: Outputs a full structured JSON object containing all settings for archival and programmatic use.</li><li><code>positive_text</code>: Outputs a clean, four-part text prompt ready to be connected to Samplers or other text-input nodes.</li></ul></li><li>Detail Level Control: Offers control over prompt verbosity with options ranging from "Brief" to "Extremely Detailed."</li></ul><h3 id="installation">Installation</h3><ol><li>Place <code>z_image_json_prompt.py</code> into your ComfyUI custom nodes directory (e.g., <code>custom_nodes/z_image_json_prompt/</code>).</li><li>Ensure you have a correct <code>__init__.py</code> file in the directory if it is a folder (see previous advice).</li><li>Restart ComfyUI. The node will be available under the <code>Z-Image</code> category as <code>Z-Image JSON Prompt Generator</code>.</li></ol># Z-Image-JSON-Prompt 🏷️一個強大且結構化的 ComfyUI / 節點式 WebUI 提示詞生成器。Z-Image-JSON-Prompt 節點旨在解決傳統文字提示詞缺乏組織和難以管理的問題。它將圖像生成的關鍵元素（場景、主體、攝影、燈光、風格）結構化，允許使用者通過清晰的選項列表和預設模板快速生成複雜、高品質的提示詞。### ✨ 核心功能* 結構化輸入：將提示詞分解為五大類 (場景、主體、攝影、燈光、風格) 和十五個子選項，使提示詞的構建邏輯清晰。* 選項自定義：節點會自動生成一個名為 <code>z_image_options</code> 的目錄，使用者可以輕鬆修改內部的 <code>.txt</code> 檔案來**增加或修改提示詞選項**。* 內建風格模板：提供十多種預設風格（如賽博朋克、奇幻魔法、電影人像等），可一鍵應用，加速創作流程。* 多語言輸出：支援 中文、英文、雙語 三種模式輸出，滿足不同模型或使用者需求。* 多格式輸出：* *<code>json_prompt</code>**：輸出包含所有設定的結構化 JSON 資料，方便追溯、存檔或程式化使用。* *<code>positive_text</code>**：輸出四段式（核心、環境、技術、風格）的純文字提示詞，可直接饋入圖像生成模型。* 細節等級控制：可選擇「簡略」、「標準」、「詳細」、「極度詳細」來控制輸出提示詞的豐富度。### 🚀 安裝與使用#### 1. 安裝1. 將 <code>z_image_json_prompt.py</code> 檔案放置到您的 ComfyUI 自定義節點目錄下（通常是 <code>custom_nodes/</code>）。或在custom_nodes新建一個資料夾(例<code>custom_nodes/z_image_json_prompt/</code>)將z_image_json_<a target="_blank" rel="ugc" href="http://prompt.py">prompt.py</a>和__init__.py放入資料夾2. 重新啟動 ComfyUI。3. 在節點選單中，您可以在 *<code>Z-Image</code>** 類別下找到 *<code>Z-Image JSON Prompt Generator</code>** 節點。#### 2. 第一次運行當您第一次運行此節點時，它會自動在您的腳本目錄下創建一個名為 *<code>z_image_options</code>** 的資料夾，其中包含：* 五個分類資料夾 <code>scene</code>, <code>subject</code>, <code>photography</code>, <code>lighting</code>, <code>style</code>)，每個資料夾內有數個 <code>.txt</code> 檔案，用於儲存選項。* *<code>templates</code> 資料夾**，內含預設的 <code>.json</code> 模板檔案。您可以編輯這些 <code>.txt</code> 或 <code>.json</code> 檔案來擴展您的提示詞庫。#### 3. 節點輸入參數說明| 參數名稱 | 類型 | 說明 | 預設值 || :--- | :--- | :--- | :--- || *<code>style_template</code>** | 選擇列表 | 一鍵選擇預設風格模板，將覆蓋對應的選項。 | <code>無模板 | No Template</code> || *<code>language_choice</code>** | 選擇列表 | 決定輸出提示詞的語言（中文/English/雙語）。 | <code>雙語 | Bilingual</code> || *<code>detail_level</code>** | 選擇列表 | 控制輸出提示詞的複雜度及描述詞的豐富度。 | <code>標準 | Standard</code> || *<code>negative_prompt</code>** | 文本輸入 | 負面提示詞，將原樣輸出。 | 預設低品質相關的提示詞。 || *<code>【...】_...</code>** | 選擇列表 | 各類型的提示詞選項。選擇 *<code>隨機 | Random</code>** 將從對應檔案中隨機抽取。 | <code>隨機 | Random</code> |#### 4. 節點輸出| 輸出名稱 | 類型 | 說明 || :--- | :--- | :--- || *<code>json_prompt</code>** | <code>STRING</code> | 完整的結構化 JSON 輸出，包含所有設定和元數據。 || *<code>positive_text</code>** | <code>STRING</code> | 四段式的純文字提示詞，可直接連線到 KSampler 或其他提示詞輸入節點。 || *<code>negative_prompt</code>** | <code>STRING</code> | 負面提示詞文本。 |只是一個簡單的COMFYUI節點,靈感來自於社群討論<a target="_blank" rel="ugc" href="https://www.reddit.com/r/StableDiffusion/comments/1p809wt/">https://www.reddit.com/r/StableDiffusion/comments/1p809wt/</a>雖然我的結論是直接輸入json內容不行會在圖片中產生大量的錯誤資訊但這個想法可以產生結構化的prompts直接把z_image_json_<a target="_blank" rel="ugc" href="http://prompt.py">prompt.py</a>放到IComfyUI\custom_nodes底下就行他會自動產生一個目錄產生所需的檔案z_image_json_<a target="_blank" rel="ugc" href="http://prompt.py">prompt.json則是示範工作流</a><h1 id="z-image-json-prompting-for-comfyui">Z-image JSON Prompting for ComfyUI</h1>A ComfyUI custom node for generating structured, detailed prompts in JSON format, inspired by the community discussion on <a target="_blank" rel="ugc" href="https://www.reddit.com/r/StableDiffusion/comments/1p809wt/">Reddit</a>.画像を表示 画像を表示 画像を表示<hr /><h2 id="concept">💡 Concept</h2>While directly feeding JSON to image models produces artifacts and errors (as tested), this node takes a different approach:✅ Generate structured JSON prompts for organization and reusability ✅ Convert to optimized text prompts for actual image generation ✅ Maintain detailed prompt components in a readable formatThink of it as a prompt construction framework rather than direct JSON-to-image generation.<hr /><h2 id="features">✨ Features</h2><h3 id="triple-output-format">📋 Triple Output Format</h3><ul><li>JSON Output -
