2024/05/30 - Amazon Bedrock Runtime - 2 new api methods
Changes This release adds Converse and ConverseStream APIs to Bedrock Runtime
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 more information, see Run inference in the Bedrock User Guide.
This operation requires permission for the bedrock:InvokeModel action.

[REQUIRED]
The identifier for the model that you want to call.
The modelId to provide depends on the type of model 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 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.

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. For more information, see Run inference in the Bedrock User Guide.
To find out if a model supports streaming, call GetFoundationModel and check the responseStreamingSupported field in the response.
For example code, see Invoke model with streaming code example in the Amazon Bedrock User Guide .
This operation requires permission for the bedrock:InvokeModelWithResponseStream action.
