MiniMax H3がArtificial Analysisで1位に——ただしオープンウェイトは2Kアップスケーリング未対応
minimaxが33bパラメータの動画モデルh3を制限付きオープンライセンスで公開し、artificial analysisの動画編集で1位、text-to-videoで2位にランクイン。動画生成におけるクローズドソースの支配に挑戦する動きだ。
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.
