MiniMax published its H3 video model weights to Hugging Face on August 3, 2026, but the MiniMax H3 Community License Agreement, effective August 2, 2026, excludes the United States, the European Union, the United Kingdom, and South Korea from its "Applicable Territory," barring users there from using, running, modifying, distributing, or deploying Outputs of locally-run H3 weights. Ryan Lee, MiniMax's Head of Developer Relations, confirmed the US restriction stems from active copyright litigation with Hollywood studios. The release includes H3-Base, a 33.1-billion-parameter dense, single-stream omni-modal transformer generating video with native stereo audio at a native canvas of 768 pixels on the short edge, plus two task-specific checkpoints—FL2VA and Ref2VA—the H3 video VAE, the audio VAE, and the Qwen3-VL-32B text encoder, the last shipping under Apache 2.0. Native ComfyUI support arrived the same day via pull request Comfy-Org/ComfyUI #15224. H3-Context-IR and H3-Regenerate-2K did not ship; both remain hosted API services, meaning flagship native 2K generation requires two MiniMax API calls routing through infrastructure subject to China's National Intelligence Law.
