The INT4 quantized version works on RTX 30-series and 40-series GPUs, while the NVFP4 version is optimized for RTX 50-series (Blackwell) GPUs. The r32 rank option requires less VRAM and runs faster, while r128 provides higher quality but needs more memory. A system with 16GB RAM and a modern CPU is recommended for smooth ComfyUI operation.\n    <\/div>\n  <\/div>\n  \n  <div class=\"faq-item\">\n    <div class=\"faq-question\">\n      <span>How does multi-image editing work in practice?<\/span>\n      <span class=\"chevron\"><\/span>\n    <\/div>\n    <div class=\"faq-answer\">\n      Multi-image editing allows you to input up to three reference images: a source image (the main image to edit), a style reference (to transfer aesthetic qualities), and an object\/scene reference (to merge elements). The model intelligently blends these inputs based on your text prompt. For example, you can take a portrait photo, a product image, and a background scene, then prompt the model to &#8220;place the person holding the product in the scenic background&#8221; for seamless compositing.\n    <\/div>\n  <\/div>\n  \n  <div class=\"faq-item\">\n    <div class=\"faq-question\">\n      <span>What are ControlNet inputs and when should I use them?<\/span>\n      <span class=\"chevron\"><\/span>\n    <\/div>\n    <div class=\"faq-answer\">\n      ControlNet inputs (depth maps, edge maps, keypoint maps) provide structural guidance to the editing process. Use depth maps when you need to maintain or modify 3D spatial relationships, edge maps for precise boundary control, and keypoint maps for human pose guidance. These are particularly useful for complex edits where text prompts alone might not provide enough control, such as maintaining specific poses or preserving architectural structures during background changes.\n    <\/div>\n  <\/div>\n  \n  <div class=\"faq-item\">\n    <div class=\"faq-question\">\n      <span>How does the quality compare between r32 and r128 rank options?<\/span>\n      <span class=\"chevron\"><\/span>\n    <\/div>\n    <div class=\"faq-answer\">\n      The r32 rank option prioritizes speed and is excellent for iterative workflows, previews, and real-time applications. It typically runs 2-3x faster than r128 with approximately 90-95% of the quality. The r128 rank option provides maximum detail preservation, better consistency in complex edits, and superior handling of fine textures. For final production outputs, especially for print or high-resolution displays, r128 is recommended. For rapid prototyping and concept exploration, r32 offers an excellent balance.\n    <\/div>\n  <\/div>\n  \n  <div class=\"faq-item\">\n    <div class=\"faq-question\">\n      <span>Can I use this model for commercial projects?<\/span>\n      <span class=\"chevron\"><\/span>\n    <\/div>\n    <div class=\"faq-answer\">\n      Yes, the Nunchaku-Qwen-Image-Edit-2509 model can be used for commercial projects, but you should review the specific licensing terms on the Hugging Face model page. The model is particularly well-suited for commercial applications like e-commerce product photography, advertising content creation, and professional photo editing services. Always ensure you have appropriate rights to the input images you&#8217;re editing, as the model doesn&#8217;t grant rights to source imagery.\n    <\/div>\n  <\/div>\n  \n  <div class=\"faq-item\">\n    <div class=\"faq-question\">\n      <span>How do I get started if I&#8217;m new to ComfyUI?<\/span>\n      <span class=\"chevron\"><\/span>\n    <\/div>\n    <div class=\"faq-answer\">\n      Start by watching the official tutorial series, particularly &#8220;ComfyUI Tutorial Series Ep 64: Nunchaku Qwen Image Edit 2509&#8221; which provides step-by-step guidance. Install ComfyUI following the official documentation, then add the ComfyUI-nunchaku extension. Download pre-built workflows from the GitHub repository to understand the node structure before creating custom workflows. The community provides extensive documentation and example workflows that demonstrate common editing tasks, making it easier to learn through practical examples.\n    <\/div>\n  <\/div>\n<\/aside>\n\n<footer class=\"references card\">\n  <h2>References and Resources<\/h2>\n  <ul>\n    <li><a href=\"https:\/\/www.youtube.com\/watch?v=O27YkFwOSHk\" target=\"_blank\" rel=\"noopener nofollow\">ComfyUI Tutorial Series Ep 64: Nunchaku Qwen Image Edit 2509<\/a><\/li>\n    <li><a href=\"https:\/\/huggingface.co\/nunchaku-tech\/nunchaku-qwen-image-edit-2509\" target=\"_blank\" rel=\"noopener nofollow\">Nunchaku-Qwen-Image-Edit-2509 Model Card on Hugging Face<\/a><\/li>\n    <li><a href=\"https:\/\/qwen.ai\/blog?id=7a90090115ee193ce6a7f619522771dd9696dd93&#038;from=research.latest-advancements-list\" target=\"_blank\" rel=\"noopener nofollow\">Qwen-Image-Edit-2509: Multi-Image Support, Improved Consistency &#8211; Official Blog<\/a><\/li>\n    <li><a href=\"https:\/\/www.datacamp.com\/tutorial\/qwen-image-edit-2509-tutorial\" target=\"_blank\" rel=\"noopener nofollow\">Qwen-Image-Edit-2509 Tutorial: Generate Studio-Ready Product Images<\/a><\/li>\n    <li><a href=\"https:\/\/www.youtube.com\/watch?v=ET1g_3Z_c0k\" target=\"_blank\" rel=\"noopener nofollow\">Run Qwen Image Edit (2509) Locally &#8211; Video Tutorial<\/a><\/li>\n    <li><a href=\"https:\/\/nunchaku.tech\/docs\/nunchaku\/usage\/qwen-image-edit.html\" target=\"_blank\" rel=\"noopener nofollow\">Qwen-Image-Edit Official Documentation &#8211; Nunchaku<\/a><\/li>\n    <li><a href=\"https:\/\/www.runcomfy.com\/comfyui-workflows\/nunchaku-qwen-image-in-comfyui-multi-image-merge-style-edit\" target=\"_blank\" rel=\"noopener nofollow\">Nunchaku Qwen Image in ComfyUI: Multi-Image Merge &#038; Style Edit Workflow<\/a><\/li>\n    <li><a href=\"https:\/\/github.com\/nunchaku-tech\/ComfyUI-nunchaku\/blob\/main\/README.md\" target=\"_blank\" rel=\"noopener nofollow\">ComfyUI-Nunchaku Extension Documentation on GitHub<\/a><\/li>\n    <li><a href=\"https:\/\/github.com\/nunchaku-tech\/nunchaku\/issues\/715\" target=\"_blank\" rel=\"noopener nofollow\">Qwen-Image-Edit-2509 Support Feature Request &#8211; GitHub Issue<\/a><\/li>\n    <li><a href=\"https:\/\/cnb.cool\/ai-models\/nunchaku-tech\/nunchaku-qwen-image-edit-2509\/-\/blob\/main\/README.md\" target=\"_blank\" rel=\"noopener nofollow\">Model Card for Nunchaku-Qwen-Image-Edit-2509 &#8211; CNB Repository<\/a><\/li>\n  <\/ul>\n<\/footer>\n    <\/div>\n<\/body>\n<\/html>\n","protected":false},"excerpt":{"rendered":"<p>Nunchaku-Qwen-Image-Edit-2509 Free Image Generate Online, Click to Use!
