On-chain news from MetaEra reveals that on August 3, MiniMax officially released the weights for its H3 video model. The launch includes two H3-Base variants—one optimized for text-to-video and first-last-frame generation, and another for image, video, and audio input. Each task is handled by a single model. H3-Base, a 33-billion-parameter dense system, supports 4–15 second, stereo 768p local outputs using SGLang, vLLM, Diffusers, and ComfyUI. The full H3 suite, including H3-Context-IR and H3-Regenerate-2K, remains proprietary and requires access via the MiniMax API for 2K results. Licensing excludes the U.S., EU, UK, and South Korea, and commercial use exceeding $200 million in revenue requires explicit approval. Token launch news continues to underscore evolving shifts in model accessibility.
ME AI News, August 3: MiniMax has officially released the weights for its video model H3. This release includes two versions of H3-Base: one designed for text-to-video and first/last frame generation, and another that simultaneously references images, video, and audio. Users select the appropriate version based on their task, without needing to load both. H3-Base is a dense model with 33 billion parameters. When deployed locally, it can generate 768p stereo audio videos ranging from 4 to 15 seconds, and supports SGLang, vLLM, Diffusers, and ComfyUI. However, this release does not include the full H3 system. Components such as H3-Context-IR (for understanding complex media relationships), H3-Regenerate-2K (for upscaling 768p results to 2K), and the sparse attention implementation remain unavailable. Developers seeking to replicate MiniMax’s full 2K results must still use the MiniMax API. Licensing also includes clear restrictions: the MiniMax H3 Community License does not apply to the United States, European Union, United Kingdom, or South Korea—users in these regions must apply for separate authorization. Commercial products with annual revenues exceeding $20 million require prior written permission from MiniMax.
