Qdrant を使った完全な RAG システム、ドキュメントの自動更新機能付き
上級
これはAI RAG, Multimodal AI分野の自動化ワークフローで、32個のノードを含みます。主にSet, Wait, GoogleDrive, HttpRequest, ManualTriggerなどのノードを使用。 OpenAI、Google Gemini、Qdrant および Google Drive を使用して、自更新 RAG システムを構築
前提条件
- •Google Drive API認証情報
- •ターゲットAPIの認証情報が必要な場合あり
- •OpenAI API Key
- •Qdrantサーバー接続情報
- •Google Gemini API Key
使用ノード (32)
