MiniMax H3 排名第一，但开源权重缺失 2K 超分模块
minimax 发布了 33b 参数的 h3 视频模型，在 artificial analysis 的视频编辑和文本生成视频榜单上分别排名第一和第二。这对闭源视频生成领域构成了挑战。
minimax released the h3 video model, a 33-billion-parameter system capable of processing text, images, video, and audio inputs to generate clips up to 15 seconds long with stereo sound. on the artificial analysis leaderboard, h3 ranked first for video editing, second for text-to-video, and third for image-to-video, outperforming many closed rivals. the model weights are open for local use and fine-tuning, but the most critical component, the 2k resolution upscaling module, remains proprietary, and commercial use is restricted to companies earning under $20 million. this release signals a shift where open-source video models can match or exceed proprietary options on specific tasks, potentially accelerating adoption for bespoke commercial applications.
