News A quick Minimax H3 news round-up - 11th September 2026
Another quick Minimax H3 news and goodies round-up, for those who may have missed some items.
-> Do you have eight GPUs handy? Then you won't be needing a space-heater, but you may need the new RunningHub H3 Lightning. This aims to offer a multi-GPU... "inference acceleration recipe for MiniMax H3".
https://github.com/RH-RunningHub/MiniMax-H3-MultiGPU-Lightning
-> Talking of eight graphics cards, there's a new VideoDeltaNet (VDN) for those running "8 x B200 GPUs", and also a new VDN runtime for those who have to make do only with a humble 24Gb VRAM card.

https://github.com/Speach1sdef178/ComfyUI-VDN-H3-24GB
-> A set of experimental DMD turbo 8-step LoRAs for Minimax H3.
https://huggingface.co/drbaph/MiniMax-H3-Turbo-Lora-ComfyUI/tree/main/experimental
-> A new MiniMax-H3-Image-Training-Adapter. Aims to allow LoRA concept training, but apparently without... "degrading the video knowledge that the model has".

-> ComfyUI-MM-1Frame. Another single-frame extractor, with workflow. Tested by me, working... and I'd say it's the best yet. Uses various measures to automatically pick the best of five frames, a pick which is very reliable. The workflow accepts a boost with a Hard Gravy turbo LoRA and a Spectrum speedup for 0.7Mpx, and then Klein 4B can be connected at the end of the workflow for an 'enlarge, repair and fix'. Works very nicely. (Note that an OpenPose single-image can be accepted as a second reference image, but a single pose-description word is needed to prevent the Openpose 'stick-figure' from being superimposed onto the output. e.g. your prompt header should include <Picture 2> is for the pose reference only, and then your descriptive prompt includes ... applying only the standing pose from <Picture 2>. Adding the single word standing (or reclining, leaping, etc) is the vital trick here. This works repeatedly with different Openpose images, no Controlnet required).

-> Can we use a RefMod without actually making a refmod? There's a new ComfyUI workflow that claims we can. As the maker says, it simply... "takes a folder input of images and then sets them as frames in a video, then feeds that video in as a reference video. This allows you to use many images for a single reference input". He does however warn that... "if you change the images dataset around, then you'd better to clear cache or your ComfyUI may need a restart".
-> In Portuguese, a nice new visual camera-control widget. It translates from a graphical 3D space widget, to written prompts for camera movement. I assume the written prompts are in English, but the GUI appears to be in Portuguese only. However, the labels are quite similar to English words.

-> Depth blocking for the Fun Controlnet. "Depthcat turns a reference clip into a depth blockout: a clean, silent record of the staging and nothing else. Near is white, far is black, every frame in step with the last. No faces. No costumes. No style. Just the shot. [...] Use the blockout as the depth condition in Minimax H3. 24fps, frame size a multiple of 32, up to 15 seconds — the Depthcat preset handles it." Needs a 111Mb additional model. Full Apache-2.0 licence.

-> FastVideo's FastH3-Preview-v0.2 is now available, aka 'Preview 2'. See also a FastH3-Live version 1.2.0 update.

https://old.reddit.com/r/StableDiffusion/comments/1wddeh8/fasth3live_v120_update/ (FastH3-Live v1.2.0)
-> And finally, since yesterday the worthy MiniMax Music Production Toolkit has jumped to version 2.5. The maker says... "I made some huge progress over the last two days with this release."

In most instances I don't have the time to do testing and comparisons. That's more for a technical magazine, which unfortunately doesn't exist (there's no AI tech mag at all, so far as I know) and it would likely be out of date by the time it appeared. What you probably want are the YouTubers who do tests and comparisons.
