調整函式呼叫

函式呼叫可讓您建立以 Gemini 為基礎的應用程式和代理程式，與即時資訊和服務互動，例如資料庫、客戶關係管理系統和文件存放區。這可強化應用程式提供相關且符合情境的回應能力。

透過監督式精細調整，您可以使用自訂的調整資料集，改善應用程式以函式呼叫為基礎的回應的整體準確度。

支援的模型

下列 Gemini 模型支援函式呼叫調整：

  • gemini-2.0-flash-001

調整用資料集格式

精細調整資料集的 fileUri 可以是 Cloud Storage 值區中檔案的 URI，也可以是公開的 HTTP 或 HTTPS 網址。

如要查看通用格式範例，請參閱 Gemini 的資料集範例。

以下各節會提供函式呼叫資料集的範例，供您在建立函式呼叫的調整工作時使用。

調整函式呼叫以產生文字

以下是用於微調函式呼叫以產生單一文字回應的資料集範例。
