target=\"_blank\">LongCat AI video generator<\/a> is an open-source, 13.6-billion-parameter deep learning model developed by Meituan that converts text prompts and static images into video sequences up to 4 minutes long.<\/p>\n\n\n\n<p>Released in late 2024, the longcat video AI system addresses a specific technical challenge in AI video generation: maintaining visual consistency across extended durations. Most <a href=\"https:\/\/gaga.art\/blog\/ai-video-generation-model\/\">AI video models<\/a> degrade in quality after 30-60 seconds due to temporal drift and color inconsistency. The long cat video AI model solves this through native pretraining on Video-Continuation tasks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"core-technical-specifications\"><strong>Core Technical Specifications<\/strong><\/h3>\n\n\n\n<p><\/p>\n\n\n\n<p>The longcat AI video generator operates with these parameters:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Model size:<\/strong> 13.6B parameters (dense architecture, all activated)<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Output resolution:<\/strong> 720p at 30 frames per second<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Maximum length:<\/strong> 240 seconds (4 minutes)<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Inference strategy:<\/strong> Coarse-to-fine generation along temporal and spatial axes<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Attention mechanism:<\/strong> Block Sparse Attention for computational efficiency<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>License:<\/strong> MIT (permits commercial use without restrictions)<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"how-does-long-cat-video-ai-work\"><strong>How Does LongCat Video AI Work?<\/strong><\/h2>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Direct Answer:<\/strong> The longcat video AI model uses a three-stage process:&nbsp;<\/p>\n\n\n\n<p>(1) coarse spatial layout generation,&nbsp;<\/p>\n\n\n\n<p>(2) temporal coherence modeling, and&nbsp;<\/p>\n\n\n\n<p>(3) fine detail refinement, all within a unified transformer architecture.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"the-technical-architecture\" style=\"font-size:24px\"><strong>The Technical Architecture<\/strong><\/h3>\n\n\n\n<p><\/p>\n\n\n\n<p>Unlike mixture-of-experts (MoE) models that route inputs to specialized sub-networks, the longcat ai video generator uses a dense architecture.
