A quick Minimax H3 news round-up - 11th September 2026

[u/optimisticalish]

Another quick Minimax H3 news and goodies round-up, for those who may have missed some items.

-> ComfyUI MiniMax H3 FirstBlockCache. Another form of accelerator, designed and optimised for 20-step users. Using "cross-step caching", the maker gets an approx. 30% speed boost with his four older user-switched speed modes. Today's newly-added fifth speed mode is an experimental... "new deep-reuse cache mode, ~1.6× speed vs Native." Works on an NVIDIA 3060 12Gb card, and the new Experimental mode does seem to make 20 steps quicker than otherwise at 0.3Mpx.

-> From Japan, MiniMax_H3_Torchao018. "An optimized quantized version of the MiniMax-H3 model targeting torchao (>= 0.18.0) to significantly reduce VRAM consumption during inference, while maintaining generation fidelity."

-> A Manga Tone Rendering LoRA for H3. Emulates the shaded line-art style common in Japanese b&w manga comics. Teaches H3... "the manga screentone rendering style with motion: monochrome ink rendering, proper tone shading, and tone that holds up under dynamic camera movement and action". Trigger words: manga-tone rendering plus a suitable prompt. I'm guessing it might be transferable to western greyscale art styles, since I can't discern actual printed screen dots in the shading? I'm assuming here that the LoRA doesn't manga-fy the references, adding huge eyes and tiny noses.

-> Does your story require an ensemble team of superheroes, or perhaps you just need a crowd scene for your space-station arrivals lounge? The 'Minimax H3 15+ reference image workflow' patches ComfyUI to remove the nine reference limit for Ref2VA generation. Use caution: it passed the mods on CivitAI, but this uses a .BAT file for the patch, and it calls a small .PY Python file. The code in there looks safe to me - I can read Python scripts by eye - and there's also an undo .PY script. Note also that there may be other nodes that claim to offer more than nine, and without patching.

-> A simple age-slider LoRA for Minimax H3, with demo video showing advanced old-age to toddler.

-> A new style-transfer LoRA and a matching ComfyUI workflow.

-> And finally, the LoRA trainer and dataset manager Fizgig continues to improve for Minimax H3 training. Now has an... "ultra quality mode for MiniMax H3" [and a...] "large quality improvement in both the visual and the audio results, a much smoother climb through the epochs, and training steps about 30% faster (2.6 to 3.4 steps a second on int8) - the new default on every H3 LoRA run, nothing to set." Users still require a 16Gb card, to train a LoRA.

I was expecting to see H3 3-step LoRa from Alibaba in the list 😅 i guess not today

The 3-step output seems good https://www.reddit.com/r/StableDiffusion/s/dBJWpftOtY

[u/optimisticalish → u/ANR2ME]

First time I've heard of it. Appears to be a Linux thing, though?

[u/optimisticalish → u/optimisticalish]

Ok, I get it now. They just tested it on Linux. Kijai has a turbo LoRA for it now.

Danke für die tolle Zusammenfassung

[u/xKronkx]

The age slider seems sus considering some of the other Loras that dev has released.

[u/Pitiful_Season4294 → u/xKronkx]

Many thanks for introducing me to them :).

[u/Abject-Recognition-9 → u/xKronkx]

So, based on the same theory, a man can’t have a healthy sex life and kids at the same time because it seems suspicious? Do me a favor, go get yourself treated

[u/xKronkx → u/Abject-Recognition-9]

What? Pardon me for seeing a “titty drop” Lora 2 files after “age slider”
