MiniMax-H3

MiniMax released H3, its first open-weight video model, and it collapses most of a pipeline into one checkpoint: text-to-video, image-to-video, frame control, reference-to-video, and motion-transfer editing. Output runs up to 2K and fifteen seconds with jointly generated stereo audio.

The local-inference story is the surprise: ComfyUI replaced roughly 40% of the parameters with a lookup table and cut the smallest variant from 123.6 GB to 42.5 GB, enough to run on an RTX 3060. The catch is legal. The license excludes the EU, UK, South Korea, and the United States, where MiniMax is a defendant in the Disney, NBCUniversal, and Warner suit over Hailuo. US creators are limited to the hosted API.
