FastVideo releases FastH3 Preview v0.1, 4-step distilled H3 checkpoints

FastVideo released four open-weight FastH3 Preview v0.1 checkpoints that cut MiniMax H3 from 49 transformer calls to four, generating 768p video with 32 kHz stereo audio. Variants explore prompt-only and synthetic-video training, and sparse and dense attention. Weights use the MiniMax H3 Community License, not a standard open-source license.
