According to CoinMeta, MiniMax H3 has been officially open-sourced, allowing users to generate 768p videos locally, but complete 2K videos still rely on the official API. This release includes two sets of h3-base models; one is responsible for text-to-video generation and generating the first and last frames of videos, while the other takes into account images, videos, and sound simultaneously. h3-base is a dense model with 33 billion parameters that supports the generation of 768p videos lasting 4 to 15 seconds with stereo sound, and it is compatible with sglang, vllm, diffusers, and comfyui. What is made available this time is not the complete h3 system; h3-context-ir, h3-regenerate-2k, and the sparse attention mechanism have not been released yet. Developers need to call MiniMax API to reproduce the complete 2K effect. Regarding licensing, minimax, h3, community, and license are not applicable in the United States, the European Union, the United Kingdom, and South Korea; separate authorization applications are required. Those with annual commercial product revenue exceeding 20 million US dollars also need to obtain written permission in advance.
