美团视频生成模型正式发布并开源

Core Insights - Meituan's LongCat team has released and open-sourced the LongCat-Video video generation model, addressing computational bottlenecks in high-resolution and high-frame-rate video generation [2] Group 1 - LongCat-Video utilizes a threefold optimization approach: "coarse-to-fine generation (C2F), block-sparse attention (BSA), and model distillation," which enhances video inference speed by 10.1 times [2]
