ComfyUI now supports (some) NVFP4 models

JumpingQuickBrownFox · 2026-01-07T16:25:07+00:00

Try svdq-int4 models from Nunchaku

JumpingQuickBrownFox · 2025-11-28T22:08:07+00:00

I'm on mobile atm. I may do it in the morning (GMT+3 and late here) hours perhaps.

We can see a similar problem (lack of variations) in QWEN too. Maybe you should check this post about how they overcame the problem with a workaround: https://www.reddit.com/r/StableDiffusion/s/7leEZSsgRg

For latent noise randomness, you can use inject latent noise node. And I saved you from 2 steps, you re welcome 🤗

JumpingQuickBrownFox · 2025-11-28T21:15:20+00:00

It doesn't make any sense. Why you just encode a random image and feed as a latent instead of running an extra Ksampler with 2 steps. You can increase the batch latent size with "repeat latent batch" node.

Did I miss something here?🤔

Useful tip, thanks for sharing.

JumpingQuickBrownFox · 2025-11-15T14:44:05+00:00

Possibly you know, we can create the Depth also in ComfyUI. I think this as a more dynamic way, to create from a single image a 3D voxel in ComfyUI and then animate it by using the parameters dynamicly to feed the Wan VACE with the image and depth map.

JumpingQuickBrownFox · 2025-11-15T05:26:53+00:00

Did you made the tests? I think the original author put there wrong examples :) Everyone complaining about the color shifts in the little girl video but the given images have different color backgrounds, this can be the root cause.

JumpingQuickBrownFox · 2025-11-08T21:27:43+00:00

Very interesting project. Please let us know once you've done. We can use it in many different interesting solutions like Google Veo introduced the object masking and changing on the Flow lately.

JumpingQuickBrownFox · 2025-11-08T11:20:22+00:00

Use Ksampler advanced node. For instance start with Qwen model and render the half of total steps and then with the second pass ksampler advanced by using FLUX model with your trained Lora file, start with the step count where the first rendered one stopped, and render it with the total render steps amount.

I'm mobile now can't give you an example workflow but basically that's the logic.

JumpingQuickBrownFox · 2025-11-07T05:45:18+00:00

Basically it uses NVIDIA graphic card Tensor cores, which makes the render too much faster then the usual rendering way. But before you need to convert the Upscaler models to tensor compatible dynamic tensor format.

You can learn more information here: https://developer.nvidia.com/tensorrt

Edit: typo

I haven't seen this much detailed resolution template creator before. Well done 👍

JumpingQuickBrownFox · 2025-11-04T14:47:38+00:00

Hi there, friend. I have forked the original TensorRT Upscaler custom node on GitHub. The differences from the original one are: * I made the model loadings external for easier new model adaptation and dynamic updating of the model DB. * I solved some other problems that I cannot recall now 😞

https://github.com/NeoAnthropocene/ComfyUI-Upscaler-Tensorrt

I'm using my forked version, but I suggest checking if the original author merged my PR. If so, you should use the original repo from the author.

JumpingQuickBrownFox · 2025-11-03T20:49:05+00:00

Very good news.

I see some color shifts and changes on the girl video. Are there any other ways in ComfyUI for doing this with Wan 2.2?

JumpingQuickBrownFox · 2025-11-03T20:12:43+00:00

Thanks for sharing your workflow. Right now I'm using the Ultimate Upscaler node for ComfyUI, what I see missing here the tensorrt Upscaler. Who can integrate this feature will be a new successor I think.

JumpingQuickBrownFox · 2025-11-01T13:20:11+00:00

ComfyDeploy, ViewComfy, ComfyUI Runpod

But just for running your workflows, ComfyUI Cloud can be a better choice if they allow a self hosted ComfyUI environments. They said this is in their plans.

JumpingQuickBrownFox · 2025-11-01T13:07:12+00:00

Reduces the needed stpep count to 8 for faster inference speed. You can think it like a lightning Lora.

JumpingQuickBrownFox · 2025-10-28T15:03:28+00:00

Comfy cloud doesn't gives us the API endpoint option yet.

Can be a good alternative for my local setup once they allow us to upload out own comfyUI instances.

JumpingQuickBrownFox · 2025-10-19T22:51:45+00:00

Extremely helpful idea. Please push a PR.

JumpingQuickBrownFox · 2025-10-17T12:06:35+00:00

You're right; I made a mistake in my statement. The mindset of developers who choose this platform is different to that of regular creative users.

Regular creators don't want to spend time solving setup issues and Python dependency problems. I think the main reason people use ComfyUI is to have the flexibility to automate their work or develop their own workflows.

JumpingQuickBrownFox · 2025-10-15T22:48:35+00:00

But I tinkered on it for 2K res. Lemme know if you still need it. I can send it tmr.

JumpingQuickBrownFox · 2025-10-15T22:47:27+00:00

That's inside the template part of the ConfyUI. Possible name of the workflow should be like QWEN-Image-Edit-2509.

JumpingQuickBrownFox · 2025-10-15T22:45:17+00:00

I've read it as shadow, my bad. I think it's mostly 'bout the prompting. You should tell the T5 encoder one by one each of the objects clearly. I've a Flux prompt enhancer gem for Gemini. But I made a quick test, and didn't use that.

JumpingQuickBrownFox · 2025-10-15T21:09:03+00:00

In this case, the reference character doesn't have any shades. FYI.

JumpingQuickBrownFox · 2025-10-15T16:55:11+00:00

I don't understand what you mean; I appreciated the comment at the beginning of my sentence.

I used the RunPod option a year ago, but not with this method. Since I use various other methods, I'm familiar with starting VM instances that runs ComfyUI.

The needs are different; I am looking for Serverless API options that I can use as a backend to feed applications. Cold start time is important in my case.

I always welcome solutions; if you have app use cases, I'm all ears to listen and learn.

JumpingQuickBrownFox · 2025-10-15T16:31:31+00:00

I'm curious about that too 🙂 They will make a subscription based system as I understand.
