Class: AWS.BedrockRuntime

Inherits:
AWS.Service show all
Identifier:
bedrockruntime
API Version:
2023-09-30
Defined in:
(unknown)

Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

Describes the API operations for running inference using Amazon Bedrock models.

Sending a Request Using BedrockRuntime

var bedrockruntime = new AWS.BedrockRuntime();
bedrockruntime.invokeModel(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the BedrockRuntime object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var bedrockruntime = new AWS.BedrockRuntime({apiVersion: '2023-09-30'});

You can also set the API version globally in AWS.config.apiVersions using the bedrockruntime service identifier:

AWS.config.apiVersions = {
  bedrockruntime: '2023-09-30',
  // other service API versions
};

var bedrockruntime = new AWS.BedrockRuntime();

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

invokeModelWithResponseStream(params = {}, callback) ⇒ AWS.Request

Invoke the specified Amazon Bedrock model to run inference using the prompt and inference parameters provided in the request body. The response is returned in a stream.

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

Note: The CLI doesn't support InvokeModelWithResponseStream.

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

This operation requires permissions to perform the bedrock:InvokeModelWithResponseStream action.

Service Reference:

Examples:

Node.js EventStream Example

// In Node.js, events are streamed and can be read as they arrive.
bedrockruntime.invokeModelWithResponseStream({/** params **/}, function(err, data) {
  if (err) {
    // handle error
    return console.error(err);
  }

  var eventStream = data.body;

  eventStream.on('data', function(event) {
    // Check the top-level field to determine which event this is.
    if (event.chunk) {
      // handle chunk event
    } else if (event.internalServerException) {
      // handle internalServerException event
    } else if (event.modelStreamErrorException) {
      // handle modelStreamErrorException event
    } else if (event.validationException) {
      // handle validationException event
    } else if (event.throttlingException) {
      // handle throttlingException event
    } else if (event.modelTimeoutException) {
      // handle modelTimeoutException event
    }
  });
  eventStream.on('error', function(err) { /** Handle error events **/});
  eventStream.on('end', function() { /** Finished reading all events **/});
});

Browser EventStream Example

// In browsers, events aren't processed until the response is fully buffered.
// Events will be accessible as an array.
bedrockruntime.invokeModelWithResponseStream({/** params **/}, function(err, data) {
  if (err) {
    // handle error
    return console.error(err);
  }

  var events = data.body;

  for (var event of events) {
    // Check the top-level field to determine which event this is.
    if (event.chunk) {
      // handle chunk event
    } else if (event.internalServerException) {
      // handle internalServerException event
    } else if (event.modelStreamErrorException) {
      // handle modelStreamErrorException event
    } else if (event.validationException) {
      // handle validationException event
    } else if (event.throttlingException) {
      // handle throttlingException event
    } else if (event.modelTimeoutException) {
      // handle modelTimeoutException event
    }
  }
});

Async Iterator EventStream Example (Experimental)

// In Node.js v10.x, Readable streams have experimental support for async iteration.
// Instead of listening to the event stream's 'data' event, you can use a for...await loop.
async function example() {
  try {
    const result = await bedrockruntime.invokeModelWithResponseStream({/** params **/}).promise();

    const events = result.body;

    for await (const event of events) {
      // Check the top-level field to determine which event this is.
      if (event.chunk) {
        // handle chunk event
      } else if (event.internalServerException) {
        // handle internalServerException event
      } else if (event.modelStreamErrorException) {
        // handle modelStreamErrorException event
      } else if (event.validationException) {
        // handle validationException event
      } else if (event.throttlingException) {
        // handle throttlingException event
      } else if (event.modelTimeoutException) {
        // handle modelTimeoutException event
      }
    }
  } catch (err) {
    // handle error
  }
}
