href="https://huggingface.co/papers/2509.24695" rel="nofollow">SANA-Video: Efficient Video Generation with Block Linear Diffusion Transformer</a> に基づく、3D データ（動画）向けの Diffusion Transformer モデルです。</p> <p>論文の抄録は以下の通りです：</p> <p><em>SANA-Video を紹介します。これは、最大 720x1280 の解像度と分単位の長さの動画を効率的に生成できる小型の拡散モデルです。SANA-Video は、RTX 5090 GPU にデプロイ可能であり、驚くほど高速な速度で、テキストと動画の整合性が強く、高解像度・高品質・長時間の動画を合成します。効率的かつ効果的な長時間動画生成を実現する 2 つの核心的な設計があります。(1) Linear DiT: 動画生成では大量のトークンを処理するため、バニラアテンションよりも効率的な線形アテンションをコア操作として活用しています。(2) Block Linear Attention 向けの定数メモリ KV キャッシュ: 線形アテンションの累積特性から導出される定数メモリ状態を採用することで、ブロック単位の自己回帰アプローチを設計し、長時間の動画生成を実現しています。この KV キャッシュにより、Linear DiT は固定のメモリコストでグローバルコンテキストを確保でき、従来の KV キャッシュの必要性を排除し、効率的な分単位の動画生成を可能にします。さらに、効果的なデータフィルタとモデル学習戦略を探索し、64 枚の H100 GPU での学習コストを 12 日間に縮小しました。これは MovieGen のコストのわずか 1% に相当します。この低コストにもかかわらず、SANA-Video は、最新の最先端の小型拡散モデル（例: Wan 2.1-1.3B や SkyReel-V2-1.3B）と比較して競争力のある性能を達成すると同時に、測定されたレイテンシでは 16 倍高速です。さらに、SANA-Video は NVFP4 精度で RTX 5090 GPU にデプロイでき、5 秒間の 720p 動画の生成における推論速度を 71 秒から 29 秒（2.4 倍高速化）に加速します。要するに、SANA-Video は低コストで高品質な動画生成を可能にします。</em></p> <p>モデルは、以下のコードスニペットで読み込むことができます。</p> <div class="code-block relative "><div class="absolute top-2.5 right-4"><button class="inline-flex items-center relative text-sm
