Amazon Bedrock 知识库还支持在解析数据或生成响应时使用推理配置文件。借助推理配置文件,您可以跟踪成本与指标,还能执行跨区域推理以将模型推理请求分发到一系列区域,从而允许更高的吞吐量。您可以在RetrieveAndGenerate或CreateDataSource请求中指定推理配置文件。有关更多信息,请参阅 使用推理配置文件设置模型调用资源。
重要
如果您使用跨区域推理,则您的数据可进行跨区域共享。
您也可以使用 SageMaker AI 模型或根据自己的数据训练的自定义模型。
注意
如果您使用 A SageMaker I 或自定义模型,则必须指定编排和生成提示(有关更多信息,请参阅中的知识库提示模板配置和自定义查询与响应生成)。您的提示必须包含信息变量,以获取用户的输入和上下文。
Amazon Bedrock 知识库中部分功能提供的区域支持与模型支持存在差异。选择一个主题以查看某项功能提供的支持:
向量嵌入支持的模型
Amazon Bedrock 知识库使用嵌入模型将数据转换为向量嵌入,并将嵌入存储在向量数据库中。有关更多信息,请参阅 将数据转换为知识库。
Amazon Bedrock 知识库支持使用以下基础模型进行矢量嵌入:
| Provider | 模型 | 模型 ID | 支持单区域模型 |
|---|---|---|---|
| Amazon | Titan Embeddings G1 - Text | 亚马逊。 titan-embed-text-v1 |

用于解析的支持的区域和模型
将数据转换为向量嵌入时,您在解析 Amazon Bedrock 知识库中的数据方面有多种不同选择。有关更多信息,请参阅 数据来源的解析选项。
下文列出了对解析选项的支持:
-
Amazon Bedrock 数据自动化功能解析器已在美国西部(俄勒冈州)推出,目前为预览版,并且可能会发生变化。
-
以下基础模型系列可用作解析器:
-
Claude 视觉模型
-
Nova 视觉模型
-
LLama 4 种视觉模型
基础模型解析可在直接使用这些模型的情况下使用(而不是通过跨区域推断)。AWS 区域有关各区域的当前模型可用性,请参阅Amazon Bedrock 中支持的根基模型。
-
支持在查询期间对结果进行重排的模型和区域
检索知识库查询结果时,您可以使用重排模型对知识库查询的结果进行重排。有关更多信息,请参阅查询知识库并检索数据和根据检索到的数据查询知识库并生成响应。
有关支持重排的模型和区域的列表,请参阅Amazon Bedrock 中支持重排的区域和模型。
带结构化数据存储的知识库支持的区域
带结构化数据存储的知识库可让您将知识库连接到结构化数据存储,并将自然语言查询转换为 SQL 查询。有关更多信息,请参阅 通过连接到结构化数据存储来构建知识库。
包含结构化数据存储的知识库可在以下位置找到AWS 区域:
