Amazon Bedrock Runtime 2023-09-30

Client: Aws\BedrockRuntime\BedrockRuntimeClient
Service ID: bedrock-runtime
Version: 2023-09-30

This page describes the parameters and results for the operations of the Amazon Bedrock Runtime (2023-09-30), and shows how to use the Aws\BedrockRuntime\BedrockRuntimeClient object to call the described operations. This documentation is specific to the 2023-09-30 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 */).

Converse ( array $params = [] )
Sends messages to the specified Amazon Bedrock model.
ConverseStream ( array $params = [] )
Sends messages to the specified Amazon Bedrock model and returns the response in a stream.
InvokeModel ( array $params = [] )
Invokes the specified Amazon Bedrock model to run inference using the prompt and inference parameters provided in the request body.
InvokeModelWithResponseStream ( array $params = [] )
Invoke the specified Amazon Bedrock model to run inference using the prompt and inference parameters provided in the request body.

Operations

Converse 

$result = $client->converse([/* ... */]);
$promise = $client->converseAsync([/* ... */]);

Sends messages to the specified Amazon Bedrock model. Converse provides a consistent interface that works with all models that support messages. This allows you to write code once and use it with different models. Should a model have unique inference parameters, you can also pass those unique parameters to the model.

For information about the Converse API, see Use the Converse API in the Amazon Bedrock User Guide. To use a guardrail, see Use a guardrail with the Converse API in the Amazon Bedrock User Guide. To use a tool with a model, see Tool use (Function calling) in the Amazon Bedrock User Guide

For example code, see Converse API examples in the Amazon Bedrock User Guide.

This operation requires permission for the bedrock:InvokeModel action.

Parameter Details

Members
additionalModelRequestFields
Type: document (null|bool|string|numeric) or an (array|associative array) whose members are all valid documents

Additional inference parameters that the model supports, beyond the base set of inference parameters that Converse supports in the inferenceConfig field. For more information, see Model parameters.

additionalModelResponseFieldPaths
Type: Array of strings

Additional model parameters field paths to return in the response. Converse returns the requested fields as a JSON Pointer object in the additionalModelResponseFields field. The following is example JSON for additionalModelResponseFieldPaths.

[ "/stop_sequence" ]

For information about the JSON Pointer syntax, see the Internet Engineering Task Force (IETF) documentation.

Converse rejects an empty JSON Pointer or incorrectly structured JSON Pointer with a 400 error code. if the JSON Pointer is valid, but the requested field is not in the model response, it is ignored by Converse.

guardrailConfig
Type: GuardrailConfiguration structure

Configuration information for a guardrail that you want to use in the request.

inferenceConfig
Type: InferenceConfiguration structure

Inference parameters to pass to the model. Converse supports a base set of inference parameters. If you need to pass additional parameters that the model supports, use the additionalModelRequestFields request field.

messages
Required: Yes
Type: Array of Message structures

The messages that you want to send to the model.

modelId
Required: Yes
Type: string

The identifier for the model that you want to call.

The modelId to provide depends on the type of model that you use:

system
Type: Array of SystemContentBlock structures

A system prompt to pass to the model.

toolConfig
Type: ToolConfiguration structure

Configuration information for the tools that the model can use when generating a response.

This field is only supported by Anthropic Claude 3, Cohere Command R, Cohere Command R+, and Mistral Large models.

ConverseStream 

$result = $client->converseStream([/* ... */]);
$promise = $client->converseStreamAsync([/* ... */]);

Sends messages to the specified Amazon Bedrock model and returns the response in a stream. ConverseStream provides a consistent API that works with all Amazon Bedrock models that support messages. This allows you to write code once and use it with different models. Should a model have unique inference parameters, you can also pass those unique parameters to the model.

To find out if a model supports streaming, call GetFoundationModel and check the responseStreamingSupported field in the response.

For information about the Converse API, see Use the Converse API in the Amazon Bedrock User Guide. To use a guardrail, see Use a guardrail with the Converse API in the Amazon Bedrock User Guide. To use a tool with a model, see Tool use (Function calling) in the Amazon Bedrock User Guide

For example code, see Conversation streaming example in the Amazon Bedrock User Guide.

This operation requires permission for the bedrock:InvokeModelWithResponseStream action.

Parameter Details

Members
additionalModelRequestFields
Type: document (null|bool|string|numeric) or an (array|associative array) whose members are all valid documents

Additional inference parameters that the model supports, beyond the base set of inference parameters that ConverseStream supports in the inferenceConfig field.

additionalModelResponseFieldPaths
Type: Array of strings

Additional model parameters field paths to return in the response. ConverseStream returns the requested fields as a JSON Pointer object in the additionalModelResponseFields field. The following is example JSON for additionalModelResponseFieldPaths.

[ "/stop_sequence" ]

For information about the JSON Pointer syntax, see the Internet Engineering Task Force (IETF) documentation.

ConverseStream rejects an empty JSON Pointer or incorrectly structured JSON Pointer with a 400 error code. if the JSON Pointer is valid, but the requested field is not in the model response, it is ignored by ConverseStream.

guardrailConfig
Type: GuardrailStreamConfiguration structure

Configuration information for a guardrail that you want to use in the request.

inferenceConfig
Type: InferenceConfiguration structure

Inference parameters to pass to the model. ConverseStream supports a base set of inference parameters. If you need to pass additional parameters that the model supports, use the additionalModelRequestFields request field.

messages
Required: Yes
Type: Array of Message structures

The messages that you want to send to the model.

modelId
Required: Yes
Type: string

The ID for the model.

The modelId to provide depends on the type of model that you use:

system
Type: Array of SystemContentBlock structures

A system prompt to send to the model.

toolConfig
Type: ToolConfiguration structure

Configuration information for the tools that the model can use when generating a response.

This field is only supported by Anthropic Claude 3 models.

stream
Type: EventParsingIterator supplying the following structures: MessageStartEvent, ContentBlockStartEvent, ContentBlockDeltaEvent, ContentBlockStopEvent, MessageStopEvent, ConverseStreamMetadataEvent, InternalServerException, ModelStreamErrorException, ValidationException, ThrottlingException

The output stream that the model generated.

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['stream'] as $event) {
    if (isset($event['contentBlockDelta'])) {
        // Handle the 'contentBlockDelta' event.
    } else if (isset($event['contentBlockStart'])) {
        // Handle the 'contentBlockStart' event.
    } else if (isset($event['contentBlockStop'])) {
        // Handle the 'contentBlockStop' event.
    } else if (isset($event['internalServerException'])) {
        // Handle the 'internalServerException' event.
    } else if (isset($event['messageStart'])) {
        // Handle the 'messageStart' event.
    } else if (isset($event['messageStop'])) {
        // Handle the 'messageStop' event.
    } else if (isset($event['metadata'])) {
        // Handle the 'metadata' event.
    } else if (isset($event['modelStreamErrorException'])) {
        // Handle the 'modelStreamErrorException' event.
    } else if (isset($event['throttlingException'])) {
        // Handle the 'throttlingException' event.
    } else if (isset($event['validationException'])) {
        // Handle the 'validationException' event.
    }
}

InvokeModel 

$result = $client->invokeModel([/* ... */]);
$promise = $client->invokeModelAsync([/* ... */]);

Invokes the specified Amazon Bedrock model to run inference using the prompt and inference parameters provided in the request body. You use model inference to generate text, images, and embeddings.

For example code, see Invoke model code examples in the Amazon Bedrock User Guide.

This operation requires permission for the bedrock:InvokeModel action.

Parameter Syntax

$result = $client->invokeModel([
    'accept' => '<string>',
    'body' => <string || resource || Psr\Http\Message\StreamInterface>, // REQUIRED
    'contentType' => '<string>',
    'guardrailIdentifier' => '<string>',
