The setup requires a GPU with at least 12GB VRAM and can be done via a desktop app or manual install. The guide covers basic workflows, advanced features like LoRA and ControlNet, and compares costs with cloud services like Midjourney.", "body_md": "Professional-grade image generation that runs entirely on your own GPU. ComfyUI + FLUX.1 Dev gives you Midjourney-quality output with full creative control and zero data leaving your machine.\n\n##\nWhat You Need\n\n- A GPU with 12GB+ VRAM (24GB recommended)\n- Python 3.10+ or the ComfyUI desktop app\n- About 20 minutes\n\n##\nSetup\n\n###\nOption A: Desktop App (Easiest)\n\nDownload from comfy.org, install, and use the built-in model manager to download FLUX.1 Dev.\n\n###\nOption B: Manual Install\n\nOpen [http://localhost:8188](http://localhost:8188).\n\n##\nBasic FLUX Workflow\n\n- Add a\n**Checkpoint Loader** node - load flux1-dev.safetensors\n- Add\n**CLIP Text Encoder** - enter your prompt\n- Add\n**KSampler** - connect model, CLIP, and empty latent\n- Add\n**VAE Decode** - decode to image\n- Add\n**Save Image** - save result\n- Click\n**Queue Prompt**\n\nPrompt example: \"a photorealistic cat sitting on a vintage leather chair, warm lighting, depth of field\"\n\n##\nAdvanced Features\n\n-\n**LoRA** - add a LoRA Loader node for style control\n-\n**ControlNet** - pose/edge guidance with extra nodes\n-\n**Image-to-Image** - feed an existing image through VAE Encode\n-\n**API mode** - integrate with n8n or custom apps\n-\n**Batch generation** - queue multiple prompts at once\n\n##\nCost vs Cloud\n\n|\nLocal |\nMidjourney |\n| Monthly |\n$0 |\n$10-60 |\n| Per image |\n$0 |\n$0.04-0.12 |\n| Privacy |\nStays on your GPU |\nSent to cloud |\n| Control |\nFull node-level |\nLimited |\n\nFull guide with troubleshooting and hardware tips: [https://everylocalai.com/stack/comfyui-flux-local-image](https://everylocalai.com/stack/comfyui-flux-local-image)", "url": "https://wpnews.pro/news/generate-professional-ai-images-locally-with-comfyui-and-flux", "canonical_source": "https://dev.to/everylocalai/generate-professional-ai-images-locally-with-comfyui-and-flux-3m7h", "published_at": "2026-06-14 21:54:00+00:00", "updated_at": "2026-06-14 22:10:55.423931+00:00", "lang": "en", "topics": ["generative-ai", "ai-tools", "computer-vision", "developer-tools", "ai-infrastructure"], "entities": ["ComfyUI", "FLUX.1 Dev", "Midjourney", "n8n", "EveryLocalAI"], "alternates": {"html": "https://wpnews.pro/news/generate-professional-ai-images-locally-with-comfyui-and-flux", "markdown": "https://wpnews.pro/news/generate-professional-ai-images-locally-with-comfyui-and-flux.md", "text": "https://wpnews.pro/news/generate-professional-ai-images-locally-with-comfyui-and-flux.txt", "jsonld": "https://wpnews.pro/news/generate-professional-ai-images-locally-with-comfyui-and-flux.jsonld"}}
