by Intel AI intel-ai/MiniMax-H3-MXFP8-CT-AutoRound

MiniMax-H3-MXFP8-CT-AutoRound is an open-weight model for text to video from Intel AI, released under other. Its published files total 188.9 GB.

An MXFP8 (OCP microscaling FP8) weight-quantized build of MiniMaxAI/MiniMax-H3 — the omni-modal (video + native stereo audio) generative DiT — produced with both diffusion transformers and the Qwen3-VL text encoder are quantized to MXFP8.

Model Card

An MXFP8 (OCP microscaling FP8) weight-quantized build of MiniMaxAI/MiniMax-H3 — the omni-modal (video + native stereo audio) generative DiT — produced with both diffusion transformers and the Qwen3-VL text encoder are quantized to MXFP8. (The companion repo MiniMax-H3-mxfp8-native quantizes only the two DiTs and keeps the text encoder in BF16 — see "Relationship to the other variants".) The large AdaLN branch of each DiT is deliberately kept in BF16. - Each DiT ~62 GB (bf16) → ~43.65 GB (≈0.71×, −29 %); AdaLN (≈13 B params/DiT) stays BF16. - Text encoder (Qwen3-VL, 64 decoder layers) ~63 GB (bf16) → ~34 GB (≈0.54×, −46 %): the model.languagemodel.layers linears are MXFP8 (448 × F8E4M3 +…

MiniMax-H3-Turbo-Lora

Larryvrh

A LoRA for MiniMax-H3 that renders joint video + synchronized stereo audio in as few as 4 sampling steps instead of the usual ~20 — a ~5× sampling speedup — and keeps getting better as you add steps. For most work, use minimaxh3turbov4step600ema.safetensors. It's the markedly better micro-detail (faces, fingers, fine texture), and the over-sharpening / plastic look of the earlier v1 (~850) line is fully resolved. v4 introduced a static-frame enhancement — a big win for static and small-motion content. The one trade-off shows up only at 4 steps with large, fast motion, where v4 can produce motion-smear / trailing ghosting (we're actively fixing this). Two things address it: - Use 6–8 steps.…

MiniMax-H3-Turbo-Lora-ComfyUI

DRBAPH

This repository contains MiniMax-H3 Turbo and few-step LoRAs converted and optimized for ComfyUI. These LoRAs accelerate MiniMax-H3 video and synchronized-audio generation by reducing the required number of sampling steps. Four HyperFlow 8-step MiniMax-H3 LoRAs are now included. They are derived from the original HyperFlow release by Video Rebirth: HyperFlow is an 8-step MiniMax-H3 LoRA designed for the MiniMax-H3 T2VA, FL2VA and Ref2VA workflows. The upstream HyperFlow implementation uses its own fixed 8-step sigma schedule. For these ComfyUI conversions, the recommended manual sigma sequence is: This is a nine-point sigma sequence defining eight denoising intervals. Use the non-pruned…

Sulphur

Sulphur 2 An uncensored video generation model based on LTX 2.3 supporting both t2v and i2v natively, as well as all of the other ltx 2.3 formats. Follow us on X Join our Discord Support the next version of the project, even just a few dollars would go a long way: Kofi To get started with the model, I recommend downloading either of the dev versions, (fp8mixed or bf16) and downloading the distill lora provided. By the way, I'm aware the workflows contain sulphurfinal right now, just use the lora or use the full models, don't use both at the same time. This model contains a prompt enhancer. The easiest way to get started with the prompt enhancer is by using it on lmstudio. The way to…
