Agents for Amazon Bedrock Runtime 2023-07-26

Client: Aws\BedrockAgentRuntime\BedrockAgentRuntimeClient
Service ID: bedrock-agent-runtime
Version: 2023-07-26

This page describes the parameters and results for the operations of the Agents for Amazon Bedrock Runtime (2023-07-26), and shows how to use the Aws\BedrockAgentRuntime\BedrockAgentRuntimeClient object to call the described operations. This documentation is specific to the 2023-07-26 API version of the service.

Operation Summary

Each of the following operations can be created from a client using $client->getCommand('CommandName'), where "CommandName" is the name of one of the following operations. Note: a command is a value that encapsulates an operation and the parameters used to create an HTTP request.

You can also create and send a command immediately using the magic methods available on a client object: $client->commandName(/* parameters */). You can send the command asynchronously (returning a promise) by appending the word "Async" to the operation name: $client->commandNameAsync(/* parameters */).

DeleteAgentMemory ( array $params = [] )
Deletes memory from the specified memory identifier.
GetAgentMemory ( array $params = [] )
Gets the sessions stored in the memory of the agent.
InvokeAgent ( array $params = [] )
The CLI doesn't support streaming operations in Amazon Bedrock, including InvokeAgent.
InvokeFlow ( array $params = [] )
Invokes an alias of a flow to run the inputs that you specify and return the output of each node as a stream.
Retrieve ( array $params = [] )
Queries a knowledge base and retrieves information from it.
RetrieveAndGenerate ( array $params = [] )
Queries a knowledge base and generates responses based on the retrieved results and using the specified foundation model or inference profile.

Paginators

Paginators handle automatically iterating over paginated API results. Paginators are associated with specific API operations, and they accept the parameters that the corresponding API operation accepts. You can get a paginator from a client class using getPaginator($paginatorName, $operationParameters). This client supports the following paginators:

InvokeAgent 

$result = $client->invokeAgent([/* ... */]);
$promise = $client->invokeAgentAsync([/* ... */]);

The CLI doesn't support streaming operations in Amazon Bedrock, including InvokeAgent.

Sends a prompt for the agent to process and respond to. Note the following fields for the request:

  • To continue the same conversation with an agent, use the same sessionId value in the request.

  • To activate trace enablement, turn enableTrace to true. Trace enablement helps you follow the agent's reasoning process that led it to the information it processed, the actions it took, and the final result it yielded. For more information, see Trace enablement.

  • End a conversation by setting endSession to true.

  • In the sessionState object, you can include attributes for the session or prompt or, if you configured an action group to return control, results from invocation of the action group.

The response is returned in the bytes field of the chunk object.

  • The attribution object contains citations for parts of the response.

  • If you set enableTrace to true in the request, you can trace the agent's steps and reasoning process that led it to the response.

  • If the action predicted was configured to return control, the response returns parameters for the action, elicited from the user, in the returnControl field.

  • Errors are also surfaced in the response.

completion
Required: Yes
Type: EventParsingIterator supplying the following structures: AccessDeniedException, BadGatewayException, PayloadPart, ConflictException, DependencyFailedException, FilePart, InternalServerException, ResourceNotFoundException, ReturnControlPayload, ServiceQuotaExceededException, ThrottlingException, TracePart, ValidationException

The agent's response to the user prompt.

contentType
Required: Yes

The MIME type of the input data in the request. The default value is application/json.

memoryId
Type: string

The unique identifier of the agent memory.

sessionId
Required: Yes
Type: string

Using an EventParsingIterator

To use an EventParsingIterator, you will need to loop over the events it will generate and check the top-level field to determine which type of event it is.

foreach($result['completion'] as $event) {
    if (isset($event['accessDeniedException'])) {
        // Handle the 'accessDeniedException' event.
    } else if (isset($event['badGatewayException'])) {
        // Handle the 'badGatewayException' event.
    } else if (isset($event['chunk'])) {
        // Handle the 'chunk' event.
    } else if (isset($event['conflictException'])) {
        // Handle the 'conflictException' event.
    } else if (isset($event['dependencyFailedException'])) {
        // Handle the 'dependencyFailedException' event.
    } else if (isset($event['files'])) {
        // Handle the 'files' event.
    } else if (isset($event['internalServerException'])) {
        // Handle the 'internalServerException' event.
    } else if (isset($event['resourceNotFoundException'])) {
        // Handle the 'resourceNotFoundException' event.
    } else if (isset($event['returnControl'])) {
        // Handle the 'returnControl' event.
    } else if (isset($event['serviceQuotaExceededException'])) {
        // Handle the 'serviceQuotaExceededException' event.
    } else if (isset($event['throttlingException'])) {
        // Handle the 'throttlingException' event.
    } else if (isset($event['trace'])) {
        // Handle the 'trace' event.
    } else if (isset($event['validationException'])) {
        // Handle the 'validationException' event.
    }
}

InvokeFlow 

$result = $client->invokeFlow([/* ... */]);
$promise = $client->invokeFlowAsync([/* ... */]);

Invokes an alias of a flow to run the inputs that you specify and return the output of each node as a stream. If there's an error, the error is returned. For more information, see Test a flow in Amazon Bedrock in the Amazon Bedrock User Guide.

The CLI doesn't support streaming operations in Amazon Bedrock, including InvokeFlow.

Parameter Syntax

$result = $client->invokeFlow([
    'enableTrace' => true || false,
    'flowAliasIdentifier' => '<string>', // REQUIRED
    'flowIdentifier' => '<string>', // REQUIRED
    'inputs' => [ // REQUIRED
        [
            'content' => [ // REQUIRED
                'document' => [
                ],
            ],

responseStream
Required: Yes
Type: EventParsingIterator supplying the following structures: AccessDeniedException, BadGatewayException, ConflictException, DependencyFailedException, FlowCompletionEvent, FlowOutputEvent, FlowTraceEvent, InternalServerException, ResourceNotFoundException, ServiceQuotaExceededException, ThrottlingException, ValidationException

The output of the flow, returned as a stream. If there's an error, the error is returned.

Using an EventParsingIterator

To use an EventParsingIterator, you will need to loop over the events it will generate and check the top-level field to determine which type of event it is.

foreach($result['responseStream'] as $event) {
    if (isset($event['accessDeniedException'])) {
        // Handle the 'accessDeniedException' event.
    } else if (isset($event['badGatewayException'])) {
        // Handle the 'badGatewayException' event.
    } else if (isset($event['conflictException'])) {
        // Handle the 'conflictException' event.
    } else if (isset($event['dependencyFailedException'])) {
        // Handle the 'dependencyFailedException' event.
    } else if (isset($event['flowCompletionEvent'])) {
        // Handle the 'flowCompletionEvent' event.
    } else if (isset($event['flowOutputEvent'])) {
        // Handle the 'flowOutputEvent' event.
    } else if (isset($event['flowTraceEvent'])) {
        // Handle the 'flowTraceEvent' event.
    } else if (isset($event['internalServerException'])) {
        // Handle the 'internalServerException' event.
    } else if (isset($event['resourceNotFoundException'])) {
        // Handle the 'resourceNotFoundException' event.
    } else if (isset($event['serviceQuotaExceededException'])) {
        // Handle the 'serviceQuotaExceededException' event.
    } else if (isset($event['throttlingException'])) {
        // Handle the 'throttlingException' event.
    } else if (isset($event['validationException'])) {
        // Handle the 'validationException' event.
    }

TextInferenceConfig

Description

Configuration settings for text generation using a language model via the RetrieveAndGenerate operation. Includes parameters like temperature, top-p, maximum token count, and stop sequences.

The valid range of maxTokens depends on the accepted values for your chosen model's inference parameters. To see the inference parameters for your model, see Inference parameters for foundation models.

Members
maxTokens
Type: int

The maximum number of tokens to generate in the output text. Do not use the minimum of 0 or the maximum of 65536. The limit values described here are arbitary values, for actual values consult the limits defined by your specific model.

stopSequences
Type: Array of strings

A list of sequences of characters that, if generated, will cause the model to stop generating further tokens. Do not use a minimum length of 1 or a maximum length of 1000. The limit values described here are arbitary values, for actual values consult the limits defined by your specific model.

temperature
Type: float

Controls the random-ness of text generated by the language model, influencing how much the model sticks to the most predictable next words versus exploring more surprising options. A lower temperature value (e.g. 0.2 or 0.3) makes model outputs more deterministic or predictable, while a higher temperature (e.g. 0.8 or 0.9) makes the outputs more creative or unpredictable.

topP
Type: float

A probability distribution threshold which controls what the model considers for the set of possible next tokens. The model will only consider the top p% of the probability distribution when generating the next token.
