MiniMax H3: Open-Weight Video Model With Built-In Stereo Audio

MiniMax released H3 on August 3, 2026 — its first open-weight video model. H3 generates up to 2K video with native stereo audio in a single forward pass, meaning no separate audio step or sync work. Weights are on Hugging Face (MiniMaxAI/MiniMax-H3). The omni-modal model takes text, images, video, or audio and produces clips up to 15 seconds.
