了解和使用安全设置

您可以使用安全设置来调整获得可能被视为有害的回答的可能性。默认情况下，安全设置会屏蔽在所有维度中不安全内容概率为中等和/或较高的内容。

Swift

您可以在创建 GenerativeModel 实例时配置 SafetySettings 。

包含一项安全设置的示例：


import FirebaseAILogic

// Specify the safety settings as part of creating the `GenerativeModel` instance.
let model = FirebaseAI.firebaseAI(backend: .googleAI()).generativeModel(
  modelName: "GEMINI_MODEL_NAME",
  safetySettings: [
    SafetySetting(harmCategory: .harassment, threshold: .blockOnlyHigh)
  ]
)

// ...

包含多项安全设置的示例：


import FirebaseAILogic

let harassmentSafety = SafetySetting(harmCategory: .harassment, threshold: .blockOnlyHigh)
let hateSpeechSafety = SafetySetting(harmCategory: .hateSpeech, threshold: .blockMediumAndAbove)

// Specify the safety settings as part of creating the `GenerativeModel` instance.

控制内容生成的其他选项

  • 详细了解 提示设计 ，以便影响模型生成符合您需求的输出。
  • 配置 模型参数 以控制模型生成回答的方式，例如输出 token 数上限、 重复输出 token 的概率等。
  • 设置系统指令 以引导模型的行为。此功能类似于您 在模型接收到最终用户的任何进一步指令之前添加的序言。
  • 传递 响应 schema 以及提示，以指定特定的输出架构。此功能最常用于生成 JSON 输出，但也可用于分类任务（例如，当您希望模型使用特定标签时）。
