Generating content

Gemini API 支持使用图片、音频、代码、工具等生成内容。如需详细了解每个功能,请继续阅读并查看以任务为中心的示例代码,或阅读综合指南。

方法:models.generateContent

根据输入 GenerateContentRequest 生成模型回答。如需详细了解用法信息,请参阅文本生成指南。输入功能因模型而异,包括经调参的模型。如需了解详情,请参阅模型指南调参指南

端点

帖子 https://generativelanguage.googleapis.com/v1beta/{model=models/*}:generateContent

路径参数

model string

必需。用于生成补全的 Model 的名称。

格式:name=models/{model}。其格式为 models/{model}

请求正文

请求正文中包含结构如下的数据:

田野
contents[] object (Content)

必需。当前与模型对话的内容。

对于单轮查询,这是指单个实例。对于多轮查询(例如 chat),此字段是重复字段,包含对话记录和最新请求。

tools[] object (Tool)

可选。Model 可用于生成下一个响应的 Tools 列表。

Tool 是一段代码,使系统能够与外部系统交互,以便在 Model 不知情和范围之外执行操作或执行一组操作。支持的 ToolFunctioncodeExecution。如需了解详情,请参阅函数调用代码执行指南。

toolConfig object (ToolConfig)

可选。请求中指定的任何 Tool 的工具配置。如需查看用法示例,请参阅函数调用指南

safetySettings[] object (SafetySetting)

可选。用于屏蔽不安全内容的唯一 SafetySetting 实例的列表。

这将在 GenerateContentRequest.contentsGenerateContentResponse.candidates上强制执行。每种 SafetyCategory 类型都不应有一项设置。此 API 将屏蔽任何未达到这些设置所设阈值的内容和响应。此列表会替换 safetySettings 中指定的每个 SafetyCategory 的默认设置。如果列表中提供的给定 SafetyCategory 没有 SafetySetting,该 API 将使用该类别的默认安全设置。支持危害类别 HARM_CATEGORY_HATE_SPEECH、HARM_CATEGORY_SEXUALLY_EXPLICIT、HARM_CATEGORY_DANGEROUS_CONTENT、HARM_CATEGORY_HARASSMENT。如需详细了解可用的安全设置,请参阅此指南。另请参阅安全指南,了解如何在 AI 应用中纳入安全注意事项。

systemInstruction object (Content)

可选。开发者设置系统说明。目前仅支持文字广告。

generationConfig object (GenerationConfig)

可选。用于模型生成和输出的配置选项。

cachedContent string

可选。已缓存的内容的名称,用作上下文以提供预测。格式:cachedContents/{cachedContent}

响应正文

如果成功,则响应正文包含一个 GenerateContentResponse 实例。

方法:models.streamGenerateContent

在给定输入 GenerateContentRequest 的情况下,根据模型生成流式响应

端点

帖子 https://generativelanguage.googleapis.com/v1beta/{model=models/*}:streamGenerateContent

路径参数

model string

必需。用于生成补全的 Model 的名称。

格式:name=models/{model}。其格式为 models/{model}

请求正文

请求正文中包含结构如下的数据:

田野
contents[] object (Content)

必需。当前与模型对话的内容。

对于单轮查询,这是指单个实例。对于多轮查询(例如 chat),此字段是重复字段,包含对话记录和最新请求。

tools[] object (Tool)

可选。Model 可用于生成下一个响应的 Tools 列表。

Tool 是一段代码,使系统能够与外部系统交互,以便在 Model 不知情和范围之外执行操作或执行一组操作。支持的 ToolFunctioncodeExecution。如需了解详情,请参阅函数调用代码执行指南。

toolConfig object (ToolConfig)

可选。请求中指定的任何 Tool 的工具配置。如需查看用法示例,请参阅函数调用指南

safetySettings[] object (SafetySetting)

可选。用于屏蔽不安全内容的唯一 SafetySetting 实例的列表。

这将在 GenerateContentRequest.contentsGenerateContentResponse.candidates上强制执行。每种 SafetyCategory 类型都不应有一项设置。此 API 将屏蔽任何未达到这些设置所设阈值的内容和响应。此列表会替换 safetySettings 中指定的每个 SafetyCategory 的默认设置。如果列表中提供的给定 SafetyCategory 没有 SafetySetting,该 API 将使用该类别的默认安全设置。支持危害类别 HARM_CATEGORY_HATE_SPEECH、HARM_CATEGORY_SEXUALLY_EXPLICIT、HARM_CATEGORY_DANGEROUS_CONTENT、HARM_CATEGORY_HARASSMENT。如需详细了解可用的安全设置,请参阅此指南。另请参阅安全指南,了解如何在 AI 应用中纳入安全注意事项。

systemInstruction object (Content)

可选。开发者设置系统说明。目前仅支持文字广告。

generationConfig object (GenerationConfig)

可选。用于模型生成和输出的配置选项。

cachedContent string

可选。已缓存的内容的名称,用作上下文以提供预测。格式:cachedContents/{cachedContent}

GenerateContentResponse

来自支持多个候选者回答的模型的响应。

对于 GenerateContentResponse.prompt_feedback 中的提示以及 finishReasonsafetyRatings 中的每个候选词,系统会报告安全评分和内容过滤。API:- 返回所有请求的候选字词,或者不返回任何候选键;仅当提示存在问题时,才会返回任何候选键(选中 promptFeedback)- 报告 finishReasonsafetyRatings 中每个候选键的反馈。

田野
candidates[] object (Candidate)

来自模型的候选响应。

promptFeedback object (PromptFeedback)

返回与内容过滤器相关的提示反馈。

usageMetadata object (UsageMetadata)

仅限输出。关于生成请求的元数据令牌用量。
