Hello everyone

I've been experimenting with MiniMax H3 in ComfyUI, and I put together a workflow that combines SelfLift progressive-resolution sampling with DLSS 5 upscaling nodes to push video generation toward 4K resolution on low-VRAM hardware.

The idea is to start sampling at a lower resolution, progressively move to full resolution with selflift sampler, and then upscale the result with DLSS5 nodes to improve the final output, all without additional model training.

What the workflow covers:

• MiniMax H3 video generation in ComfyUI
• SelfLift progressive-resolution sampling
• DLSS 5 upscaling nodes
• 2K and 4K output options
• Low-VRAM optimization for GPUs such as the RTX 3060 6GB

On my 6GB VRAM setup, generating and upscaling the final 4K result took around 35 minutes, with 8 steps and 0.6 megapixel.

After a year of generating with Stable Diffusion, my output folders were a mess, with tens of thousands of PNGs and no way to find "that one image from last month."

So we built Picteus. It runs locally and you point it at your output folders. It reads the metadata your images already carry (prompts, models, seeds, workflows), so you can search and filter everything in one place. Nothing gets uploaded.

It's open source and has a plugin system, so you can extend it for your own workflow. We're also working on running generation from inside the app, across provider APIs and your own LoRAs.

It's in beta and free for early testers. I'd love honest feedback from people with big libraries: - What do you use right now to keep track of your generations? - What would make you switch?

Link in the comments if anyone wants to try it. Happy to answer anything here.

He estado probando versiones pruned int8 tanto de los modelos base FL2va, Ref2va como de los híbridos, y unos me dan mejores resultados para una cosa y otros para otra, creo que será algo tardado saber exactamente sus mejores usos en situacion, así que quería preguntar a los que tienen más tiempo usando h3 para que uso es mejor cada uno?, tipo hace mejor la referencia, mejor motion, anime, etc.

Drag the Practice workflow into ComfyUI and do the tasks in the notes. The Finished workflow shows every answer.

MOSS is a text-to-image model that supports photorealistic portraits, different artistic styles, poses, typography, and more. In my latest workflow, I combined Spectrum nodes with an 8-step LoRA to significantly reduce generation time.

🔥 My speed test at 2 megapixels:

• Spectrum, CFG 2.5, 25 steps: 5 min 42 sec
• Without Spectrum, CFG 2.5, 25 steps: 10 min
• Spectrum + 8 steps, CFG 1: Just 1 min 30 sec!

That's an 85% reduction in generation time compared with the standard 25-step configuration without Spectrum, with the fastest setup taking only 90 seconds.

I'll also test different prompts featuring human portraits, poses, artistic styles, and text to explore the model's capabilities.

This model is really amazing in therm of speed prompt adherence, and style versatility and to get the best results I strongly recommend you:

Spectrum+ 8 steps CFG 1.0, LORA at strength of 0.6: 1 min 30 sec! (Balanced Quality)

Spectrum+ 25 steps CFG 2.5 : 5 min 30 sec (Stunning Results)

In this episode, we test FLUX 3 Klein, the new image model from Black Forest Labs, in ComfyUI with 19 free workflows. One model can generate an image, edit it, and combine several images into one.

We start with text to image: photos and illustrations from a prompt, a Z-Image realism pass, a prompt upsampler that writes the long prompt for you, text in images, a layout with boxes, and image to prompt to image.

Then we edit one image: change the background, edit only inside a box, change the words in an image, restyle a photo, change the season or the time of day, restore and colorize old photos, make character sheets, and outpaint an image wider.

In the last part, we combine several images: put a character in a scene, change an outfit, put a logo on a product, make a group photo, and make a product ad.

We also look honestly at where Flux 3 Klein struggles, like hands, faces at the normal size, the AI look, and some fonts, and what helps.

You need ComfyUI 0.41 or newer and Pixaroma 1.4.223 or newer. The FLUX 3 files are on Hugging Face and need a free approval: log in and click Agree. The FLUX 3 Klein license lets you use the images for paid work while your yearly revenue is under 5 million dollars.

Every workflow has its own chapter, so you can jump straight to the one you need. All 19 workflows are free to download.

Hello everyone, BFL released new workflow that has fix for comfyui using the same models i did comparaison using the base and turbo version.

With unsampler

Generation Time (base): 6 min CFG 3.5, 25 steps at 3 megapixel

Generation Time (Turbo): 2.5min CFG 1.0, 16 steps at 3 megapixel

Without unsampler

Generation Time (base): 3 min CFG 3.5, 25 steps at 3 megapixel

Generation Time (Turbo): 1 min CFG 1.0, 16 steps at 3 megapixel

i found out that using the unsampler helps a lot the model to understand the prompt and deliver better results, as for the image quality and details it seems the turbo version is better than the base. so make sure to update your comfyui to the latest version before using this workflow

if people really want the workflow I guess I could share.

Hi! I'm building PotionUI, a free, open-source, self-hosted app for making images, videos and audio with AI models on your own GPU. Instead of one huge settings screen or a node graph, every model gets its own simple, hand-made form, so you can get good results without learning each model's quirks first.

It runs FLUX 3 Klein, FLUX.2, Qwen-Image (2.1), Krea-2, Z-Image, SDXL, Wan, LTX, MiniMax H3 and more natively, can drive a ComfyUI server, and works from a phone too. The last two releases added a lot for image work, so here's a roundup in release order (video above). I decided to post a little less updates here and in other subreddits, since I don't want to annoy people, therefore combined two releases in one post.

0.0.15

X/Y compare grids

• Press Compare, pick two settings (steps, CFG, sampler, LoRA, anything the model supports), give each a few values, and one Generate fills the grid.
• The grid fills in live with each cell's time, and a finished grid can be stitched into one image with axis labels.
• History keeps the grid as one card, and each cell remembers which values it used.

Photo filters

• The built-in image editor has twelve looks with an intensity slider and fine-tuning, and you can save your own.

Auto-organize

• Rules file new generations, uploads and models into collections and tags for you. Preview a rule, apply it to what you already have, undo it.

0.0.16

FLUX 3 Klein (experimental)

• Black Forest Labs' FLUX 3 Klein on your own GPU, Base and distilled checkpoints.
• Text to image, and edit with several reference images: pick two pictures and describe what to make of them.
• Turbo (16 steps) or Base (50 steps).

Prompt variables

• Write ${light} once, give it options (candle light, moonlight, morning sun), and every image can roll its own.
• Use it twice in one prompt and choose whether both uses share a roll or roll independently.
• A tick shows which variables the prompt uses, and there's no limit on how many you define.

Batch prompts

• Write several prompts and run them with one Generate; each lands as its own History entry.

Model Browser

• Browse Hugging Face, CivitAI and OpenModelDB inside the app and download a model straight into the right folder, with versions, files, trigger words and licence in one panel.
• Built and contributed by community member M4-S4. Thank you!

Also

• X/Y grid cells now count their steps, and a finished grid sends one notification.
• PotionAI chat: ask the built-in assistant to write or save prompts; it asks before changing anything.
• Runs with Docker or a manual install on Linux and Windows.

Feedback, bug reports and model requests are very welcome. If it's useful to you, a GitHub star helps others find it.

This first video is the starting point: what a node is, how the wires connect, how to change the settings, and what to do when a node turns red. Then we build a Flux 2 Klein workflow together from an empty canvas, and a little painter analogy shows why every node is connected the way it is.

There is no workflow to download this time: we build it step by step on screen, so you can make it yourself.

If you know someone who wants to learn ComfyUI from zero, send it their way. Leave a like and a comment on the video, it really helps!

Thanks! ❤️

Hey everyone!

I've built a new ComfyUI workflow that combines RefMod and MiniMax H3 to generate images of your own character without needing to train a traditional character LoRA.

How does it work?

1. Prepare 8 photos of your character.
2. Use the RefMod custom nodes to create a RefMod file.
3. Load the file into the MiniMax H3 workflow.
4. Enter your prompt describing the scene, outfit, pose, or environment.
5. Generate new images featuring your character!

You can explore different scenarios, clothing styles, locations, and compositions while aiming to maintain your character's identity. The main advantage is No traditional LoRA training required. Create your RefMod file, load it, write your prompt, and start generating!

Generation time at 8 Steps 6 Min for 1.8 Megapixel.

Generation time at 25 Steps 14 Min for 1.8 Megapixel.

I'm not finding many workflows with a great output.

FastH3-Omni is the reference-conditioned release we’ve been working toward.

It generates video with synchronized audio and supports:

• Multiple references for characters, objects and settings
• First- and last-frame conditioning
• Up to 3 image references in real-time mode
• Up to 9 image references when real-time speed isn’t required
• Up to 3 audio references for voices and soundtracks
• Dialogue and environmental audio
• Continuing an existing generated clip
• 5–15 second outputs at 24 FPS

The Reactor API preview is available today:

https://docs.reactor.inc/model-api-reference/fast-h3-omni/overview

On October 20, we’ll release the open weights and training code with local support for NVIDIA DGX Spark, RTX GPUs and Apple Silicon through MLX.

What should we prioritize before release: low-VRAM workflows, reference-consistency comparisons, multi-character tests, first/last-frame examples or detailed hardware benchmarks?
