⚡ Flux Klein High-Res Powerhouse (4K & 8K Workflows)
Unlock the full potential of Flux Klein. These workflows allow you to generate incredible high-resolution images, reaching 4K and even 45MP (8K) resolutions, utilizing the efficiency of Klein models.
I have included two versions of this workflow to suit your specific hardware and quality needs.
📂 The Two Versions
1. 🚀 Performance Hybrid (Speed)
Filename: Flux_Klein_9b_with4b_upscaler.json
Best for: Faster generation times while still maintaining excellent resolution.
How it works:
Stage 1: Generates the base composition using the Klein Base 9b model.
Stage 2: Upscales the image (2x or 4x) using the lightweight Klein 4b (4-step) model.
2. 💎 Ultimate Fidelity (Quality)
Filename: Flux_Klein_9b_with_9b_Upscaler.json
Best for: Maximum detail, texture consistency, and highest quality output.
How it works:
Stage 1: Generates the base composition using the Klein Base 9b model.
Stage 2: Upscales using the more robust Klein 9b (4-step) model for superior refinement during the upscale process.
✨ Key Features
Extreme Resolution: Capable of generating standard images and upscaling them to 4K or 8K (45MP).
Smart Tiled Upscaling: Uses a "Divide and Conquer" strategy combined with Florence2. The workflow automatically captions the image before upscaling to guide the diffusion model, ensuring the upscale respects the context of the image.
Efficient: By utilizing the Klein quantized models, you get Flux capabilities with a much friendlier VRAM footprint.
🛠️ Requirements & Setup
To use these workflows, you will need the following models in your ComfyUI models folders:
Checkpoints (UNET):
flux-2-klein-base-9b.safetensors
flux-2-klein-4b.safetensors (for the speed version)
Upscale Model:
- 4xNomosUniDAT_otf.pth (or your preferred 4x upscaler)
Nodes: Ensure you have the necessary custom nodes installed (specifically ComfyUI-Florence2, ComfyUI_Steudio (for Divide & Conquer), and ComfyUI-GGUF if using GGUF versions).
