Sends messages to the specified Amazon Bedrock model and returns the response in a stream

Description

Sends messages to the specified Amazon Bedrock model and returns the response in a stream. converse_stream 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.

See https://www.paws-r-sdk.com/docs/bedrockruntime_converse_stream/ for full documentation.

Usage

bedrockruntime_converse_stream(
  modelId,
  messages,
  system = NULL,
  inferenceConfig = NULL,
  toolConfig = NULL,
  guardrailConfig = NULL,
  additionalModelRequestFields = NULL,
  additionalModelResponseFieldPaths = NULL
)

Arguments

modelId	[required] The ID for the model. The modelId to provide depends on the type of model or throughput that you use: If you use a base model, specify the model ID or its ARN. For a list of model IDs for base models, see Amazon Bedrock base model IDs (on-demand throughput) in the Amazon Bedrock User Guide. If you use an inference profile, specify the inference profile ID or its ARN. For a list of inference profile IDs, see Supported Regions and models for cross-region inference in the Amazon Bedrock User Guide. If you use a provisioned model, specify the ARN of the Provisioned Throughput. For more information, see Run inference using a Provisioned Throughput in the Amazon Bedrock User Guide. If you use a custom model, first purchase Provisioned Throughput for it. Then specify the ARN of the resulting provisioned model. For more information, see Use a custom model in Amazon Bedrock in the Amazon Bedrock User Guide. The Converse API doesn't support imported models.
messages	[required] The messages that you want to send to the model.
system	A system prompt to send to the model.
inferenceConfig	Inference parameters to pass to the model. converse_stream supports a base set of inference parameters. If you need to pass additional parameters that the model supports, use the additionalModelRequestFields request field.
toolConfig	Configuration information for the tools that the model can use when generating a response. This field is only supported by Anthropic Claude 3 models.
guardrailConfig	Configuration information for a guardrail that you want to use in the request.
additionalModelRequestFields	Additional inference parameters that the model supports, beyond the base set of inference parameters that converse_stream supports in the inferenceConfig field.
additionalModelResponseFieldPaths	Additional model parameters field paths to return in the response. converse_stream 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_stream 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_stream.
