このページでは、AlloyDB Omni をインストールして AlloyDB AI を統合する方法について説明します。
AlloyDB AI は、エンタープライズ生成 AI アプリケーションを構築できる AlloyDB Omni に含まれる一連の機能です。AlloyDB の ML 機能の詳細については、生成 AI アプリケーションを作成するをご覧ください。
AlloyDB Omni で AlloyDB AI を使用すると、リモート ML モデルをクエリして、ML モデルから生成されたオンライン予測とテキスト エンベディングを操作できます。また、google_ml.predict_row インターフェースを使用してクエリ内で変換を行うなど、画像などの他のコンテンツからベクトル エンベディングを処理することもできます。
AlloyDB Omni と AlloyDB AI をインストールする場所に応じて、次のいずれかのオプションを選択します。
