Best upscale model comfyui reddit. g. A pixel upscale using a model like ultrasharp is a bit better -and slower- but it'll still be fake detail I tried all the possible upscalers in ComfyUI (LDSR, Latent Upcale, several models such as NMKV, the Ultimate SDUpscale node, "hires fix" (yuck!), the Iterative Latent upscale via pixel space node (mouthful), and even bought a license from Topaz to compare the results with Faststone (which is great btw for this type of work). What has worked best for me has been 1. There will probably be AI errors in the pics as I'd rather show what the model can do before using things like Inpaint to fix them. It's not practical to use in your workflow for every generation. We’re on a journey to advance and democratize artificial intelligence through open source and open science. But occasionally I want them closer to 4k, which is the step I'm currently missing. Running it locally using ComfyUI. Here are some of the top upscalers used in AI workflows, including those compatible with ComfyUI and Stable Diffusion: Feb 6, 2026 · The best practice in AI pipelines usually combines both steps. Only need comfyui-impact-pack, wd14tagger and optionally LoRA manager custom nodes. A pixel upscale using a model like ultrasharp is a bit better -and slower- but it'll still be fake detail Apr 13, 2025 · The best upscaler depends on your specific use case (e. That's practically instant but doesn't do much either. There are a lot of options in regards to this, such as iterative upscale; in my experience, all of them are too intensive for bad GPUs or they are too inconsistent. Running it through an image upscale on bilinear and 3. It's a 128px model so the output faces after faceswapping is blurry and low res. We would like to show you a description here but the site won’t allow us. 3 distilled model or dev model with Lora at 8 step are not good as Veo 3. 2 with steadily improving results. Only using the T2V Low Noise model and passing it through x2 upscale. Encoding it and doing a tiny refining step to sharpen up the edges. Tiled SEGS with per segment prompt (courtesy of comfyui-impact-pack). We aim to provide a better way to find and compare models than existing sources. Reactor has built in codeformer and GFPGAN, but all the advice I've read said to avoid them. Upscaling: Increasing the resolution and sharpness at the same time. Perfect for transforming ideas into stunning visuals using text-to-image prompts. Traditionally, super-resolution aimed to preserve the original signal, which you can also easily achieve in ComfyUI. Can’t understand and implement prompts fully. Ultimate SD upscale is probably the best we got atm but it's very slow. Creative Upscale vs. Explore AI image generators with our free photo generators & editors. dev model to use without Lora and not for distilled model? I tried optimizing comfyui template which is for distilled model but results was not good. Curious if anyone knows the most modern, best ComfyUI solutions for these problems? Detailing/Refiner: Keeping same resolution but re-rendering it with a neural network to get a sharper, clearer image. Use a focused purpose-trained ESRGAN model like the one you (incorrectly) suggested was somehow outdated in the thread body post to upscale your initial output, and THEN run a secondary detailing pass on it with Stable Diffusion. Decoding the latent 2. What's the recommended way to fix the faces after upscaling (assuming photoreal)? Is it facedetailer, running another upscaler, or something else? Hey guys, I’m fairly new to ComfyUI AI video models and have been running LTX 2. Results of Ltx 2. ), the desired quality, and the computational resources available. "Best" depends on what you value the most. I am curious both which nodes are the best for this, and which models. Conservative Upscale Diffusion models and generative AI changed what “upscaling” means. Apr 10, 2025 · Most of the time I only need to upscale them to about 2k (so somewhere in the 2000x2000 region, depending on aspect ratio). Fastest would be a simple pixel upscale with lanczos. This article does not focus on this. I tried all the possible upscalers in ComfyUI (LDSR, Latent Upcale, several models such as NMKV, the Ultimate SDUpscale node, "hires fix" (yuck!), the Iterative Latent upscale via pixel space node (mouthful), and even bought a license from Topaz to compare the results with Faststone (which is great btw for this type of work). 1 with official Comfyui FLF and I2V workflow. But I’ve never given The best place to find AI Upscaling models OpenModelDB is a community driven database of AI Upscaling models. Mar 24, 2026 · Feeling similar with WAN2.
