Amazon Bedrock 知識庫也支援使用推論設定檔來剖析資料或產生回應。透過推論設定檔，您可以追蹤成本和指標，也可以執行跨區域推論，將模型推論請求分散到一組區域，以允許更高的輸送量。您可以在 RetrieveAndGenerate 或 CreateDataSource 請求中指定推論設定檔。如需詳細資訊，請參閱使用推論設定檔設定模型調用資源。
重要
如果您使用跨區域推論，您的資料可以跨區域共用。
您也可以使用 SageMaker AI 模型或根據自己的資料訓練的自訂模型。
注意
如果您使用 SageMaker AI 或自訂模型，則必須指定協同運作和產生提示 (如需詳細資訊，請參閱 設定和自訂查詢和回應產生 中的知識庫提示範本)。您的提示必須包含資訊變數，才能存取使用者的輸入和內容。
Amazon Bedrock 知識庫中某些功能的區域和模型支援有所不同。選取主題以檢視功能的支援：
向量嵌入支援的模型
Amazon Bedrock 知識庫使用嵌入模型將您的資料轉換為向量嵌入，並將嵌入存放在向量資料庫中。如需詳細資訊，請參閱將資料轉換為知識庫。
Amazon Bedrock 知識庫支援使用下列基礎模型的向量內嵌：
| 供應商 | 模型 | 模型 ID | 單一區域模型支援 |
|---|---|---|---|
| Amazon | Titan Embeddings G1 - Text | amazon.titan-embed-text-v1 |
ap-northeast-1 eu-central-1 us-east-1 us-west-2 |

嵌入模型支援下列向量類型。
| 模型名稱 | 支援的向量類型 | 支援的維度數目 |
|---|---|---|
| Amazon Titan Embeddings G1 - Text | 浮點 | 1536 |
| Amazon Titan 文本嵌入 V2 | 浮點，二進位 | 256、512、1024 |

剖析支援的模型和區域
將資料轉換為向量嵌入時，您在 Amazon Bedrock 知識庫中剖析資料時有不同的選項。如需詳細資訊，請參閱剖析資料來源的選項。
下列清單支援剖析選項：
-
美國西部 (奧勒岡) 支援 Amazon Bedrock Data Automation 剖析器，且預覽版中可能會有所變更。
-
下列基礎模型系列可作為剖析器使用：
-
Claude 視覺模型
-
Nova 視覺模型
-
LLama 4 視覺模型
基礎模型剖析適用於直接提供這些模型的 AWS 區域（而不是透過跨區域推論）。如需目前按區域的模型可用性，請參閱 Amazon Bedrock 中支援的基礎模型。
-
支援在查詢期間重新排名結果的模型和區域
擷取知識庫查詢結果時，您可以使用重新排名模型來重新排名知識庫查詢的結果。如需詳細資訊，請參閱查詢知識庫並擷取資料及查詢知識庫並根據擷取的資料產生回應。
如需支援重新排名的模型和區域的清單，請參閱 Amazon Bedrock 中支援重新排名的區域和模型。
具有結構化資料存放區的知識庫支援區域
具有結構化資料存放區的知識庫可讓您將知識庫連線至結構化資料存放區，並將自然語言查詢轉換為 SQL 查詢。如需詳細資訊，請參閱透過連線至結構化資料存放區來建立知識庫。
具有結構化資料存放區的知識庫提供如下AWS 區域：
-
歐洲 (法蘭克福)
-
歐洲 (蘇黎世)
-
歐洲 (愛爾蘭)
