v1.2.61 - Minimax H3 open weights

[imprsnst]

Summary

MiniMax H3 open weights now run locally on the Inline Core engine, as four nodes on the canvas. Video and its 32 kHz stereo soundtrack come out of a single denoising pass, so a take is one MP4 with the audio already in it.

Four nodes

• Text to Video, prompt only
• Image to Video, a still into motion
• First and Last Frame, pin either end or both
• Reference to Video, up to nine images, three clips and three audio clips, addressed by position in the prompt

How it runs

• Loads the original bf16 checkpoints. Nothing repacked, so a new build needs no code change.
• The modulation weights, 40 percent of the transformer, are factorised at load: 66.3 GB down to 40.3 GB.
• The conditioner steps off the card once the prompt is encoded, so the denoiser keeps the card for the whole denoise.

Measured on an L40S

• A 10 second clip at 960x544 takes about 7.2 minutes
• Peak VRAM 38.9 GB
• 46.7 GB of system RAM that cannot be reclaimed, so plan on 64 GB

Licence

Inline Studio ships no model weights. The H3 weights are licensed separately by MiniMax under a community licence that excludes several territories. Read it before you build on it.
