REST

在使用任何请求数据之前，请先进行以下替换：

• PROJECT_NUMBER_OR_ID：您的 Google Cloud 项目的数字或字母数字 ID。
• LOCATION：处理请求的位置。可用的选项包括：

  点击即可展开可用区域的部分列表

  • us-central1
  • us-west4
  • northamerica-northeast1
  • us-east4
  • us-west1
  • asia-northeast3
  • asia-southeast1
  • asia-northeast1
• MODEL_ID：模型的 ID，例如 gemini-1.0-pro-002
• SOURCE_LANGUAGE_CODE：输入文本的语言。
• TARGET_LANGUAGE_CODE：要将输入文本翻译成的目标语言。
• SOURCE_TEXT：要翻译的文本。
• TEMPERATURE：温度 (temperature) 在生成回答期间用于采样，在应用 topP 和 topK 时会生成回答。温度可以控制词元选择的随机性。 较低的温度有利于需要更少开放性或创造性回复的提示，而较高的温度可以带来更具多样性或创造性的结果。温度为 0 表示始终选择概率最高的词元。在这种情况下，给定提示的回复大多是确定的，但可能仍然有少量变化。

  如果模型返回的回答过于笼统、过于简短，或者模型给出后备回答，请尝试提高温度。

• TOP_P：Top-P 可更改模型选择输出词元的方式。系统会按照概率从最高（见 top-K）到最低的顺���选择词元，直到所选词元的概率总和等于 top-P 的值。例如，如果词元 A、B 和 C 的概率分别为 0.3、0.2 和 0.1，并且 top-P 值为 0.5，则模型将选择 A 或 B 作为下一个词元（通过温度确定），并会排除 C，将其作为候选词元。

  指定较低的值可获得随机程度较低的回答，指定较高的值可获得随机程度较高的回答。

• TOP_K：Top-K 可更改模型选择输出词元的方式。如果 top-K 设为 1，表示所选词元是模型词汇表的所有词元中概率最高的词元（也称为贪心解码）。如果 top-K 设为 3，则表示系统将从 3 个概率最高的词元（通过温度确定）中选择下一个词元。

  在每个词元选择步骤中，系统都会对概率最高的 top-K 词元进行采样。然后，系统会根据 top-P 进一步过滤词元，并使用温度采样选择最终的词元。

  指定较低的值可获得随机程度较低的回答，指定较高的值可获得随机程度较高的回答。

• MAX_OUTPUT_TOKENS：回答中可生成的词元数量上限。词元约为 4 个字符。100 个词元对应大约 60-80 个单词。

  指定较低的值可获得较短的回答，指定较高的值可获得可能较长的回答。

• SAFETY_CATEGORY：要为其配置阈值的安全类别。可接受的值包括：

  点击即可展开安全类别

  • HARM_CATEGORY_SEXUALLY_EXPLICIT
  • HARM_CATEGORY_HATE_SPEECH
  • HARM_CATEGORY_HARASSMENT
  • HARM_CATEGORY_DANGEROUS_CONTENT
• THRESHOLD：基于概率阻止属于指定安全类别的回答的阈值。可接受的值包括：

  点击即可展开屏蔽阈值

  • BLOCK_NONE
  • BLOCK_ONLY_HIGH
  • BLOCK_MEDIUM_AND_ABOVE（默认）
  • BLOCK_LOW_AND_ABOVE
  BLOCK_LOW_AND_ABOVE 屏蔽得最多，而 BLOCK_ONLY_HIGH 屏蔽得最少。
