Distillation (ADD) を紹介します。これは、大規模な基盤となる画像拡散モデルをわずか 1〜4 ステップで効率的にサンプリングしつつ、高い画像品質を維持する、新しい学習手法です。スコア蒸留を用いて、大規模な市販の画像拡散モデルを教師シグナルとして活用するとともに、敵対的損失を組み合わせることで、1 ステップまたは 2 ステップという低ステップ領域においても高い画像忠実性を確保します。分析の結果、当社のモデルは、1 ステップにおいて既存の少ステップ手法（GAN、Latent Consistency Models）を明確に上回り、わずか 4 ステップで最先端の拡散モデル（SDXL）の性能に達することが示されました。ADD は、基盤モデルによる 1
