Package-level declarations

Contains APIs related to model invocation and querying of knowledge bases.

Creates a new invocation within a session. An invocation groups the related invocation steps that store the content from a conversation. For more information about sessions, see Store and retrieve conversation history and context with Amazon Bedrock sessions.

Creates a session to temporarily store conversations for generative AI (GenAI) applications built with open-source frameworks such as LangGraph and LlamaIndex. Sessions enable you to save the state of conversations at checkpoints, with the added security and infrastructure of Amazon Web Services. For more information, see Store and retrieve conversation history and context with Amazon Bedrock sessions.

Deletes memory from the specified memory identifier.

Deletes a session that you ended. You can't delete a session with an ACTIVE status. To delete an active session, you must first end it with the EndSession API operation. For more information about sessions, see Store and retrieve conversation history and context with Amazon Bedrock sessions.

Ends the session. After you end a session, you can still access its content but you can’t add to it. To delete the session and it's content, you use the DeleteSession API operation. For more information about sessions, see Store and retrieve conversation history and context with Amazon Bedrock sessions.

Generates an SQL query from a natural language query. For more information, see Generate a query for structured data in the Amazon Bedrock User Guide.

Gets the sessions stored in the memory of the agent.

Retrieves the flow definition snapshot used for a flow execution. The snapshot represents the flow metadata and definition as it existed at the time the execution was started. Note that even if the flow is edited after an execution starts, the snapshot connected to the execution remains unchanged.

Retrieves details about a specific flow execution, including its status, start and end times, and any errors that occurred during execution.

Retrieves the details of a specific invocation step within an invocation in a session. For more information about sessions, see Store and retrieve conversation history and context with Amazon Bedrock sessions.

Retrieves details about a specific session. For more information about sessions, see Store and retrieve conversation history and context with Amazon Bedrock sessions.

Lists events that occurred during a flow execution. Events provide detailed information about the execution progress, including node inputs and outputs, flow inputs and outputs, condition results, and failure events.

Lists all executions of a flow. Results can be paginated and include summary information about each execution, such as status, start and end times, and the execution's Amazon Resource Name (ARN).

Lists all invocations associated with a specific session. For more information about sessions, see Store and retrieve conversation history and context with Amazon Bedrock sessions.

Lists all invocation steps associated with a session and optionally, an invocation within the session. For more information about sessions, see Store and retrieve conversation history and context with Amazon Bedrock sessions.

Lists all sessions in your Amazon Web Services account. For more information about sessions, see Store and retrieve conversation history and context with Amazon Bedrock sessions.

List all the tags for the resource you specify.

Add an invocation step to an invocation in a session. An invocation step stores fine-grained state checkpoints, including text and images, for each interaction. For more information about sessions, see Store and retrieve conversation history and context with Amazon Bedrock sessions.

Reranks the relevance of sources based on queries. For more information, see Improve the relevance of query responses with a reranker model.

Queries a knowledge base and retrieves information from it.

Queries a knowledge base and generates responses based on the retrieved results and using the specified foundation model or inference profile. The response only cites sources that are relevant to the query.

Starts an execution of an Amazon Bedrock flow. Unlike flows that run until completion or time out after five minutes, flow executions let you run flows asynchronously for longer durations. Flow executions also yield control so that your application can perform other tasks.

Stops an Amazon Bedrock flow's execution. This operation prevents further processing of the flow and changes the execution status to Aborted.

Associate tags with a resource. For more information, see Tagging resources in the Amazon Bedrock User Guide.

Remove tags from a resource.

Updates the metadata or encryption settings of a session. For more information about sessions, see Store and retrieve conversation history and context with Amazon Bedrock sessions.

Create a copy of the client with one or more configuration values overridden. This method allows the caller to perform scoped config overrides for one or more client operations.
