⚡ MINIMAX H3 TURBO LoRA
4-STEP AUDIO + VIDEO ACCELERATION
EXTREME SPEED // NATIVE AUDIO // COMFYUI READY
MiniMax H3 Turbo LoRA is an experimental acceleration adapter designed to drastically reduce MiniMax H3 video generation time while preserving its native synchronized stereo audio capabilities.
It reduces sampling from the usual higher step count down to only 4 steps, providing extremely fast previews and significantly shorter generation times.
The LoRA supports both:

IMAGE TO VIDEO
FIRST / LAST FRAME VIDEO⚠️ EARLY EXPERIMENTAL RELEASE
This LoRA is currently an experimental and under-trained prototype.
The 4-step mode provides impressive speed, but it may produce:
Softer image quality
Reduced fine details
Unstable textures
Motion ghosting
Motion trails
Lower overall quality compared with the full MiniMax H3 model
For improved visual quality, using 6 to 8 steps may produce cleaner results while still remaining much faster than standard generation.
🚀 RECOMMENDED SETTINGS
LoRA Strength : 1.0
Steps : 6–8 recommended
Fast Preview : 4 steps
Scheduler : simple
CFG : 1.0 or workflow default
Frame Rate : 24 FPS
Resolution : multiples of 32
Short Edge : approximately 768 pxRecommended LoRA file
minimax_h3_turbo_4step_ckpt500.safetensorsThe non-EMA ckpt500 version is currently the recommended checkpoint.
The EMA version may produce softer results and can be more prone to ghosting or visible motion trails.
🔊 NATIVE SYNCHRONIZED AUDIO
MiniMax H3 generates video and audio together:
VIDEO STREAM
+
32 kHz STEREO AUDIOThe audio is generated natively and synchronized directly with the video.
A dedicated Turbo sampler is required because MiniMax H3 uses different sampling trajectories for video and audio:
Video Flow Shift : 12
Audio Flow Shift : 3Using a standard ComfyUI sampler at only 4 steps may incorrectly sample the audio component, resulting in distorted, saturated, or unusable sound.
🧩 REQUIRED COMFYUI CUSTOM NODE
Install the following custom node through ComfyUI Manager:
ComfyUI-MiniMax-H3-TurboOfficial repository:
https://github.com/Larryvrh/ComfyUI-MiniMax-H3-Turbo
The node pack includes:
MiniMax-H3 Turbo LoRA
MiniMax-H3 Turbo SamplerThe custom node also supports pruned MiniMax H3 checkpoints by automatically applying the required AdaLN LoRA layers during generation.
🧠 BASE MODEL COMPATIBILITY
The Turbo LoRA is compatible with several MiniMax H3 model formats:
BF16
INT8 ConvRot
Pruned INT8
Pruned FP8The dedicated Turbo node automatically detects the model structure and applies the LoRA appropriately.

⚡ SPEED AND QUALITY GUIDE
4 STEPS = MAXIMUM SPEED / PREVIEW QUALITY
6 STEPS = BALANCED TURBO MODE
8 STEPS = BEST CURRENT TURBO QUALITYThe Turbo LoRA is especially useful for:
Rapid prompt testing
Motion previews
Seed comparison
Fast workflow testing
Video drafts
Quickly testing image-to-video inputs
Reducing MiniMax H3 sampling time
For maximum final quality, the standard MiniMax H3 model without the Turbo LoRA and with a higher step count may still produce better results.

Description
⚡ MiniMax H3 Turbo — 4 Step EMA CKPT850
🏎️ Extreme speed mode for MiniMax H3
This version is made for users who want to push MiniMax H3 toward very low-step generation and much faster iteration.
The 4 Step EMA CKPT850 LoRA is more aggressive than the newer V4 version and focuses heavily on speed.
It is especially useful for quick testing, preview renders and experimenting with prompts before launching a heavier final generation.
🎯 What can you expect?
This LoRA can produce usable MiniMax H3 results with:
⚡ 4–6 steps
It is especially useful for:
✅ Fast previews
✅ Prompt testing
✅ Seed searching
✅ Camera testing
✅ Motion concept testing
✅ Workflow experimentation
✅ Quickly checking whether an idea works
At 4 steps, generation can be extremely fast compared to standard H3.
At 6 steps, results generally become noticeably more stable.
⚙️ Recommended settings
LoRA Strength: 1.0
Steps: 4–6
Scheduler: Simple
Base Model: Compatible MiniMax H3 model
💡 For simple or slow-moving scenes, 4 steps can work surprisingly well.
💡 For more demanding motion, try 6 steps.
⚠️ Known limitations
Because this version is more aggressive, quality compromises can be more visible.
Possible issues include:
⚠️ Plastic-looking skin
⚠️ Over-sharpened details
⚠️ Extra grain or noise
⚠️ Motion ghosting
⚠️ Motion smear during fast action
⚠️ Less stable hands and fingers
⚠️ Reduced detail during complex movement
⚠️ Lower consistency with multiple characters
⚠️ Possible audio degradation
⚠️ Less stable synchronization in demanding scenes
Very fast movement, fighting scenes, dancing, running or complex physical interaction may expose these limitations more clearly.
💡 Best use case
Think of this version as:
🚀 Fast preview mode
🚀 Prompt testing mode
🚀 Seed hunting mode
🚀 Quick experimental H3 mode
Then, once you find a good prompt or seed, you can rerender using more steps or switch to V4 Step600 for better refinement.

❤️ Huge thanks to the original creator for making MiniMax H3 Turbo generation possible.
💙 Recommendation:
Use CKPT850 for speed and experimentation, and V4 Step600 for the best overall balance between quality and generation time.
