Flux.2-Klein Tiling Upscale Workflow
A 20x upscale using Klein tiling nodes and Color Anchor—zero quality loss.
A new community-driven workflow for ComfyUI pushes image upscaling to extreme limits. The Flux.2-Klein Tiling Upscale Workflow, shared by Reddit user Enshitification, demonstrates scaling from a modest 0.5 megapixels to a massive 10 megapixels—a 20x increase. While the creator notes the result isn't perfect, it serves as a robust proof of concept for those needing ultra-high-resolution outputs from AI-generated images.
The workflow integrates two key components: the Color Anchor node by capitan01R and the Steudio tiling nodes. The Color Anchor node helps maintain color consistency during the tiling process, while the Steudio tiling nodes handle the segmentation and seamless recombination of image tiles. The entire setup runs inside ComfyUI, a popular node-based interface for Stable Diffusion workflows. The author provides a direct link to the workflow on Pastebin, encouraging users to tweak parameters for better results. This technique is particularly valuable for artists and developers working with Flux.2 models, where native resolution limits can hinder large-format prints or detailed renders.
- Achieves 20x upscale from 0.5 MP to 10 MP using ComfyUI.
- Uses Color Anchor node by capitan01R and Steudio tiling nodes.
- Workflow available via Pastebin link for community tweaking.
Why It Matters
Enables AI artists to produce ultra-high-resolution images beyond native model limits for professional printing.
