Part 2 of my Lab series. Checkout my other workflows on my profile, they can all be used in conjunction!
Sorry for the clutter! - subgraphs seem to break during upload (NSFW Update has the fixed version)
⚡ Ultimate Adaptive Upscale & Detail Workflow
A professional-grade ComfyUI upscale pipeline built for every VRAM tier — from high-end workstations to mid-range rigs. No compromises, no separate workflows. One unified system that intelligently scales to your hardware while delivering exceptional output quality.
🎯 Three-Tier VRAM Adaptive Upscaling
Forget juggling multiple workflows for different hardware. This pipeline gives you three battle-tested upscale paths under one roof:
🔥 High VRAM — SeedVR
For those with the horsepower to match their ambitions. SeedVR delivers state-of-the-art upscaling with fine detail reconstruction that has to be seen to be believed. If your rig can run it, this is the gold standard.
⚖️ Medium VRAM — Hybrid SeedVR / RealESRGAN 2x
The best of both worlds. A carefully tuned hybrid pipeline combines SeedVR's perceptual quality with RealESRGAN 2x's efficiency, giving mid-range GPUs results that punch well above their weight class. Smooth, detailed, and fast.
💡 Low VRAM — 4x NOMOS
No high-end GPU? No problem. The 4x NOMOS path is optimised for memory-constrained systems without sacrificing the quality you came for. Clean upscales, full detail, minimal VRAM footprint.
🔍 Intelligent Regional Detailing
Upscaling alone isn't enough — this workflow goes further with a fully integrated regional detail pass powered by both BBox detection and SAM segmentation models . Target exactly what matters:
Face — Reconstruct natural skin texture, pores, and subtle facial structure with dedicated face detailing prompts
Eyes — Crisp, lifelike eyes with catchlight preservation and iris detail that holds up at any resolution
Hands — The historic weak point of AI generation, addressed directly with targeted hand correction and refinement
Each region accepts its own prompt , giving you surgical control over how each area is enhanced independently of the rest of the image.
🔄 Dual-Pass Base + Refiner Pipeline
Quality doesn't stop at upscaling. Every image runs through a full two-stage generation pass :
Base model pass — Rebuilds and enhances the upscaled image with a full denoise pass, locking in coherent structure, lighting, and composition
Refiner pass — A dedicated high-frequency refinement stage that sharpens fine detail, corrects micro-artifacts, and elevates the final output to a level a single pass simply cannot match
This dual-pass approach is what separates good upscales from exceptional ones.
💼 Who Is This For?
Artists who demand production-ready output at any scale
Workflows that need hardware flexibility without quality sacrifice
Anyone tired of soft, over-smoothed, or anatomically broken upscales
Creators who want prompt-driven control over every region of their image
Drop it into your ComfyUI workflows folder and let it do the heavy lifting. Your images deserve better than a single-pass upscale.
