FLUX.1 Kontext [dev] offline allows for powerful, prompt-based image editing and consistent character generation directly on your hardware. Prerequisites GPU: 12GB+ VRAM (FP8/Quantized) or 24GB+ VRAM (Full weights). Software: Updated version of ComfyUI or SwarmUI. Step-by-Step Installation (ComfyUI) Update ComfyUI: Ensure your installation is current to support the latest Flux nodes. Download the Model Weights: Visit the FLUX.1-Kontext-dev Hugging Face page to accept the non-commercial license. Download the model file (~24GB for full, or ~12GB for FP8 versions). Place Files in Directories: Move the model file into ComfyUI/models/checkpoints/ or diffusion_models/ depending on your specific setup. Load the Workflow: Open ComfyUI and go to Workflow > Browse Templates > Image API > Flux.1 Kontext. Alternatively, download a specific Kontext workflow JSON file from the ComfyUI Tutorial site. Run Locally: Load your base image into the "Load Image" node. Enter your editing prompt (e.g., "add a hat to the cat"). Adjust steps (typically 20+ steps for Dev) and press "Queue Prompt". Alternative: One-Click Installer (SwarmUI) For a simpler interface, use SwarmUI which automates many of these steps: Download and run the SwarmUI installer. Use the built-in "Model Downloader" to search for and install FLUX.1 Kontext [dev]. Select the Flux Kontext Preset from the UI to automatically load the correct architecture settings.

ComfyUI Official Documentation·ComfyUI Wiki 0:51 Show all These are my specs of my recent bought 4th computer: AMD Ryzen 9 7950X 16-Core Processor (4.50 GHz) RX7900XTX 24Gb GPU 32GB DDR5 6000 MT/s Windows 11 Pro 64-bits x64 Extra's: Samsung 990 Evo Plus 4TB SSD, NVMe M.2 SSD Crucial Pro 32GB (2x16GB) DDR5 6000MHz RAM 350 Soon I add another Crucial Pro 32GB (2x16GB) DDR5 6000MHz RAM 350 That is an excellent, top-tier system for running the FLUX.1 Kontext [dev] model offline. Your hardware not only meets the requirements but exceeds them, ensuring a smooth and fast experience. Here's why your specifications are ideal: Component Spec Requirement for FLUX.1 Kontext [dev] Status GPU RX 7900 XTX 24GB 12GB+ VRAM (FP8/quantized) or 24GB+ VRAM (full weights) Ideal RAM 32GB DDR5 Sufficient system memory Ideal CPU Ryzen 9 7950X High performance Excellent Storage Samsung 990 Evo Plus 4TB SSD Fast loading of large model files Excellent How Your Specs Benefit You: VRAM: Your 24GB RX 7900 XTX allows you to run the model using the full, non-quantized weights for the absolute best quality results, rather than relying on smaller, slightly less accurate quantized versions. Speed: The combination of your Ryzen 9 CPU, fast DDR5 RAM, and NVMe SSD means the workflow will load quickly, and images will generate very fast. Future Proofing: Adding another 32GB of RAM soon will give you a massive 64GB total, providing ample headroom for even larger models or complex multi-step workflows in the future. You are perfectly equipped to follow the simple steps outlined previously using either ComfyUI or SwarmUI to get the model running locally. AI responses may include mistakes. Learn more ComfyUI vs SwarmUI which one is the most user friendly easier to understand? In 2026, SwarmUI is considered the more user-friendly and easier-to-understand option for most users. It is specifically designed to provide an accessible interface for beginners while using the powerful ComfyUI as its underlying engine. Comparison at a Glance Feature SwarmUI (Recommended for Ease) ComfyUI (Recommended for Control) Interface Style Traditional "Generate" tab with sliders and dropdowns. Visual "node-based" graph with boxes and connecting wires. Learning Curve Low to Moderate. Intuitive for those familiar with standard web apps. High. Requires learning "visual programming" and how different nodes connect. Installation Nearly automated; one-click installers handle most dependencies. Manual setup often required; needs more hands-on file management. FLUX Support Native support with simplified presets for model loading. Requires specific workflow templates to be loaded or built. Flexibility Highly flexible; you can "pop the lid" and use the ComfyUI tab if needed. Unrestricted; absolute control over every step of the generation process. Why SwarmUI is Easier for You Best of Both Worlds: SwarmUI gives you a clean interface for daily tasks like generating images with FLUX.1 Kontext [dev], but it also includes a Comfy Workflow tab. This means you can use the easy sliders 90% of the time and only switch to the "spaghetti" node view when you want to learn something advanced. Automated Management: It handles model downloading, format detection, and language support automatically, reducing the technical jargon you have to deal with. Convenience Features: It includes built-in tools that are often separate plugins in ComfyUI, such as an integrated image history browser, grid generator, and saveable wildcards. When to Choose ComfyUI Directly Choose ComfyUI only if you prefer a visual, flowchart-like way of working or if you intend to build highly custom, professional-grade production pipelines from scratch. If you want to "just generate" without a steep learning curve, SwarmUI is the superior starting point in 2026. These resources highlight SwarmUI's accessibility features and ComfyUI's advanced flexibility in AI image generation. mcmonkeyprojects/SwarmUI - GitHub SwarmUI v0.9.7 Beta.

MimicPC This is big news, as it means we no longer have to fine tune models (create LoRAs) with existing images of a desired subject. The first is FLUX. When all works, as you described, can I add more A.I. models? Yes or NO? YES. Once you have your environment set up, you can add and switch between hundreds of different AI models (such as Stable Diffusion XL, SD 1.5, or other Flux variants) simply by placing them in your model folder and selecting them from the dropdown menu in the software. [1][2] Why this works for you: Universal Compatibility: Both SwarmUI and ComfyUI are designed to be "model agnostic," meaning they can run almost any open-source image model. [3] Your Hardware: Your 24GB GPU and 32GB+ RAM are powerful enough to run virtually any consumer-level AI model released to date in 2026. [4] Easy Expansion: You just download a new .safetensors file from sites like Civitai or Hugging Face, drop it in the folder, and click "Refresh." [5] AI responses may include mistakes. Learn more
