MiniMax H3 排名第一，但開源權重缺失 2K 超分模組
minimax 發布了 33b 參數的 h3 視訊模型，在 artificial analysis 的視訊編輯和文本生成視訊榜單上分別排名第一和第二。這對閉源視訊生成領域構成了挑戰。
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.
