Sand AI 開源 MAGI-1 視頻生成模型：無限擴展、高保真
2025 年 4 月 21 日，Sand AI 發佈開源視頻生成模型 MAGI-1，以其創新的自迴歸擴散架構和卓越性能，迅速成爲生成式 AI 領域的焦點。該模型採用 Apache 2.0 許可，代碼、權重和推理工具已在 GitHub 和 Hugging Face 開放，爲全球開發者提供強大創作工具。MAGI-1 基於擴散變換器架構，引入塊因果注意力、並行注意力塊、Sandwich 規範化等技術創新，通過分塊生成（每塊 24 幀）實現高效視頻生成。其獨特流水線設計支持並行處理，最多可同時生成四個塊，大幅提升效率。模型通過快捷蒸餾技術，支持靈活的
