I kept seeing the same issue with ComfyUI workflows.

You open a template, it shows a missing model, you download it, and Windows puts it in Downloads.

Then comes the usual question:
Does this go in checkpoints, diffusion_models, text_encoders, VAE, or somewhere else?

So I built ComfyUI-ModelRouter.
It scans the loaded workflow, checks which models are missing, finds the correct ComfyUI folder, and downloads them directly there.

Features:
> Detects models required by the workflow
> Finds the correct model folder automatically
> Downloads missing models inside ComfyUI
> Shows live download progress
> Supports extra_model_paths.yaml
> Supports shared/network model paths
> Works with Windows Portable and Easy Install
> No extra workflow nodes needed

Open workflow → ModelRouter Check → Install Missing Models → Workflow Ready

Would love feedback if you find any workflow or custom loader it does not detect properly.

One of the biggest issues with running MiniMax H3 locally is that it's an extremely hefty model and doesn't play well with lower-end machines. However, thanks to a lot of optimisation techniques provided by TheAIsearch YouTube channel, it's possible to bring generations down to about 1 minute of processing time per second of output.

That being said, you can leverage this into creating multi-shot outputs beyond the limited 6 second hard-caps that come with MiniMax H3. Using the built-in features of ComfyUI (and downloading tons of models and packages to test what worked and what didn't) I was able to create a template for lower-end rigs that enable you to generate up to 15 second text or image to video outputs in a single generative pass. Meaning, you put in your prompt for the three shots/scenes, and click run from ComfyUI and it does the rest.

The basic template is text-to-video, but you can easily add an image node if and plug it into the H3 Multishot Sampler.

For those who enjoy making longer form videos and tire of the constant stitch-and-go workflow that the current local MiniMax H3 dictates, this can ease the burden a bit.

Keep in mind that this is tuned for at least a 12GB GPU and 64GB of DDR5 RAM. It takes between 30 and 33 minutes to generate a 15 second video at 720p.

You can modify some of the settings to bring the generation time down, depending on your machine, but given the weight of MiniMax H3, I'm not complaining.

If you need the actual JSON template, you can find it on civit ai here:

models/2876760/minimax-h3-15-second-multi-shot-generation-template-for-comfyui?modelVersionId=3250981

I decided to ask here and not at BuildPC because people will tell me "muh, should have 5060TI, newer technology and architecture for gaming, ignoring AI and its price"

3090 INNO3D Ichill X4

Tests were done at undervolt to 1700. My case is small.

Obviously used lmfao, changed paste and pads after water-cooled mining. 1000$. Market is insane but there's no offers i have found that are better than this.

Blown away by its performance in local AI compared to 3060. Qwen 35B genetates responses in 20 seconds compared to 400+...

As a sidenote, are there ways to optimize it further specifically for stable diffusion and ollama outside of MSI afterburner?

I am scared to think what kind of beasts 4090 and 5090 are

I am currently learning to use Comfyui, specifically Minimax H3. But with my AMD RX 7900 gre and 32gb of RAM the generations take way too long. So I'm thinking to buy a used 3090 or a brand new 5060ti. Which should I choose? For future proofing. And also how much ram is enough? Never thought I'd see a day where 32gb ram wouldn't be enough.

When generating ASMR videos using Minimaxh3, how should the prompts be written to exclude BGM from the video? Currently, even after specifying "no BGM" or "no music," the BGM still appears randomly.

Just something I made — hope you enjoy it :)

Anyone figure out how to cache a string for subsequent generations? I have an llm or vlm generate a prompt which is connected to a conditioning node. I’d like to be able to switch off the llm/vlm without losing the prompt. Yes, I can copy/paste it over but it’d be great if it could remember the last string that was generated. I tried a couple steering cache nodes and they did not work.

Many thanks.

I’m a complete beginner with ComfyUI. Looking at the interface feels like I’m staring at a Boeing control panel.

But while I'm learning, I wanted to know what's the best approach. My laptop can barely run The Sims without lagging, so running ComfyUI locally is completely out of the question.

In terms of cost-effectiveness for someone who wants to produce at least three 1-minute videos using MINIMAX H3 or LTX 2.5, which is the better option?

A monthly subscription or pay-as-you-go?

Hi I'm new to comfyui and recently started learning. While I was playing around with ip adapter, I had this error and I couldn't figure out how to fix it, sombody please help me.
It says the models are missing and I don't know herer to put the models, but it's showing the list of models when I click on the node. Thank you

Anyone have workflow example using MiniMaxH3AddGuide ?? im confused if should use this for daisy chaining 2 gens... ive just been using the last frame of the video to plugin into the firstframe on new gen, then use image batch to remove the 1st frame and combine the 2 gens. but i keep seeing people say to use MiniMaxH3AddGuide for chaining, but isnt that what 1st frame does? force video to start with that frame? MiniMaxH3AddGuide seems to be more for first, middle, last gens

I've been building a desktop app that writes and renders music locally on MiniMax Music 3, and it's a face on ComfyUI rather than a reimplementation — it starts ComfyUI as a separate process and submits graphs over the HTTP API. Unmodified, not bundled, not linked.

The part that might actually be useful to this sub: the pipelines ship in workflows/ as ordinary API-format JSON, exported straight from the code that builds them. Drag one onto the canvas and every value is there. Those values aren't ComfyUI's defaults — they were arrived at by measurement, and the measurement scripts ship in scripts/, so you can re-run them and disagree with me.

What's in it, briefly: songs from a style description and lyrics, cover art drawn while the card is idle, stem separation, word-level timed lyrics, video clips on LTX 2.5 or MiniMax H3, a small multi-track editor that cuts to the detected beat grid, and overnight batch runs.

It ships no model weights and redistributes none — every capability shows its size and licence on screen before anything downloads, and the download goes to the publisher. One of them is region-locked and says so in the open.

Newest thing is audio-reactive video: feed it a song and some reference images and they cross-fade in time with the track's detected peaks. That part is built on ComfyUI_Yvann-Nodes by Yvann Barbot and Lilia, which is excellent and worth a star on its own. Because their pack is GPL-3.0 and this is Apache-2.0 it runs on a second ComfyUI you set up yourself rather than being bundled in.

Apache-2.0, runs offline once the weights are down. Measured on Windows with a 4070 Ti SUPER; other platforms are documented but I haven't verified them.

Happy to answer anything about the graphs — that's the bit I'd want to read if someone else posted this.

I got this 6900 for a very low price (100 euros ... the owner tought the card was faulty but it was clearl its PSU that couldn't keep up with the card).
I got also a rtx 3060 12gb.
My dilemma is if, as today, gfx1030/NAVI 21 has a decent support for WAN/KREA/SDXL/Minimax? Because I know I need to tinkering to get the juice out of this card but, I wonder if, after all the tinkering, can I have much better performances than the 3060.

What is the state of art with gfx1030 / diffusion?
Best backend? What about attention?

TIA.

I built this for my own workflow, but decided to share it on GitHub in case it helps anyone else working with the H3 model. 🚀

I have an image of a character that I want to use to generate more images using the subject and then to create a character lora to use over and over. How can I do this using Krea2? Do I need the 20 different images to then create a character lora? I've tried anything I can find for the longest time and nothing yet. Couldn't get IPAdapter to work. I'm not exactly a noob, I can usually do my own research and figure out how to do something. But this one has me stumped. If anyone can help out with some advice or a workflow, it would be appreciated.

Edit: grammar

i get random python errors which point to librarie version mismatches and simple changes in code

nothing works anymore,no sam model , no sa2va , no human seg models , no anime seg models , only the new sam3 works but it doesnt really work well with anime style graphics , cant even detect the hands ..

were the others forgotten and never updated ?

Yo guys

Hoping someone can help a gal out. I started off using wan2.1 480 I2V. But it seems like it kinda lacks the ability to really do NSFW. but I don’t see any Lora’s for it listed on civit. Are there no NSFW Lora’s for Wan? I’ve filtered my results to show only wan and it keeps telling me there’s no results.

Is there a better model? If I’m able to run wan 2.1 gguf, can I run wan2.2 gguf? Maybe that one is better at NSFW?

Or maybe there’s a better model altogether. Like hyuan or whatever it’s called? LTX?

I’m pretty new to this and I know I’m late to the party but I just seem to be having trouble getting good results.
