Overview

An API client for BedrockRuntime. To construct a client, you need to configure a ‘:region` and `:credentials`.

client = Aws::BedrockRuntime::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the [developer guide](/sdk-for-ruby/v3/developer-guide/setup-config.html).

See #initialize for a full list of supported configuration options.

:credentials (required, Aws::CredentialProvider) —
Your AWS credentials. This can be an instance of any one of the following classes:
- ‘Aws::Credentials` - Used for configuring static, non-refreshing credentials.
- ‘Aws::SharedCredentials` - Used for loading static credentials from a shared file, such as `~/.aws/config`.
- ‘Aws::AssumeRoleCredentials` - Used when you need to assume a role.
- ‘Aws::AssumeRoleWebIdentityCredentials` - Used when you need to assume a role after providing credentials via the web.
- ‘Aws::SSOCredentials` - Used for loading credentials from AWS SSO using an access token generated from `aws login`.
- ‘Aws::ProcessCredentials` - Used for loading credentials from a process that outputs to stdout.
- ‘Aws::InstanceProfileCredentials` - Used for loading credentials from an EC2 IMDS on an EC2 instance.
- ‘Aws::ECSCredentials` - Used for loading credentials from instances running in ECS.
- ‘Aws::CognitoIdentityCredentials` - Used for loading credentials from the Cognito Identity service.
When ‘:credentials` are not configured directly, the following locations will be searched for credentials:
- ‘Aws.config`
- The ‘:access_key_id`, `:secret_access_key`, and `:session_token` options.
- ENV, ENV
- ‘~/.aws/credentials`
- ‘~/.aws/config`
- EC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of ‘Aws::InstanceProfileCredentails` or `Aws::ECSCredentials` to enable retries and extended timeouts. Instance profile credential fetching can be disabled by setting ENV to true.
:region (required, String) —
The AWS region to connect to. The configured ‘:region` is used to determine the service `:endpoint`. When not passed, a default `:region` is searched for in the following locations:

- ‘Aws::StaticTokenProvider` - Used for configuring static, non-refreshing tokens.
- ‘Aws::SSOTokenProvider` - Used for loading tokens from AWS SSO using an access token generated from `aws login`.
When ‘:token_provider` is not configured directly, the `Aws::TokenProviderChain` will be used to search for tokens configured for your profile in shared configuration files.
:use_dualstack_endpoint (Boolean) —

When set to ‘true`, dualstack enabled endpoints (with `.aws` TLD) will be used if available.

#converse(params = {}) ⇒ `Types::ConverseResponse`

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.

Options Hash (params):

:model_id (required, String) —
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.

:messages (required, Array<Types::Message>) —

The messages that you want to send to the model.
:system (Array<Types::SystemContentBlock>) —

A system prompt to pass to the model.
:inference_config (Types::InferenceConfiguration) —

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.
:tool_config (Types::ToolConfiguration) —
Configuration information for the tools that the model can use when generating a response.

<note markdown=“1”> This field is only supported by Anthropic Claude 3, Cohere Command R, Cohere Command R+, and Mistral Large models.
```
</note>
```
:additional_model_request_fields (Hash, Array, String, Numeric, Boolean) —

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].

Document type used to carry open content (Hash,Array,String,Numeric,Boolean). A document type value is serialized using the same format as its surroundings and requires no additional encoding or escaping.

[1]: docs.aws.amazon.com/bedrock/latest/userguide/model-parameters.html
:additional_model_response_field_paths (Array<String>) —

Additional model parameters field paths to return in the response. ‘Converse` returns the requested fields as a JSON Pointer object in the `additionalModelResultFields` 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`.

Returns:

(Types::ConverseResponse) —
Returns a response object which responds to the following methods:
- #output => Types::ConverseOutput
- #stop_reason => String
- #usage => Types::TokenUsage
- #metrics => Types::ConverseMetrics
- #additional_model_response_fields => Hash,Array,String,Numeric,Boolean

def converse(params = {}, options = {})
  req = build_request(:converse, params)
  req.send_request(options)
end

#converse_stream(params = {}) ⇒ `Types::ConverseStreamResponse`

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][2: 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.

Examples:

EventStream Operation Example


You can process the event once it arrives immediately, or wait until the
full response is complete and iterate through the eventstream enumerator.

To interact with event immediately, you need to register #converse_stream
with callbacks. Callbacks can be registered for specific events or for all
events, including error events.

Callbacks can be passed into the `:event_stream_handler` option or within a
block statement attached to the #converse_stream call directly. Hybrid
pattern of both is also supported.

`:event_stream_handler` option takes in either a Proc object or
Aws::BedrockRuntime::EventStreams::ConverseStreamOutput object.

Usage pattern a): Callbacks with a block attached to #converse_stream
  Example for registering callbacks for all event types and an error event

  client.converse_stream( # params input# ) do |stream|
    stream.on_error_event do |event|
      # catch unmodeled error event in the stream
      raise event
      # => Aws::Errors::EventError
      # event.event_type => :error
      # event.error_code => String
      # event.error_message => String
    end

    stream.on_event do |event|
      # process all events arrive
      puts event.event_type
      ...
    end

  end

Usage pattern b): Pass in `:event_stream_handler` for #converse_stream

  1) Create a Aws::BedrockRuntime::EventStreams::ConverseStreamOutput object
  Example for registering callbacks with specific events

    handler = Aws::BedrockRuntime::EventStreams::ConverseStreamOutput.new
    handler.on_message_start_event do |event|
      event # => Aws::BedrockRuntime::Types::messageStart
    end
    handler.on_content_block_start_event do |event|
      event # => Aws::BedrockRuntime::Types::contentBlockStart
    end
    handler.on_content_block_delta_event do |event|
      event # => Aws::BedrockRuntime::Types::contentBlockDelta
    end
    handler.on_content_block_stop_event do |event|
      event # => Aws::BedrockRuntime::Types::contentBlockStop
    end
    handler.on_message_stop_event do |event|
      event # => Aws::BedrockRuntime::Types::messageStop
    end
    handler.on_metadata_event do |event|
      event # => Aws::BedrockRuntime::Types::metadata
    end
    handler.on_internal_server_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::internalServerException
    end
    handler.on_model_stream_error_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::modelStreamErrorException
    end
    handler.on_validation_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::validationException
    end
    handler.on_throttling_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::throttlingException
    end

  client.converse_stream( # params input #, event_stream_handler: handler)

Parameters:

params (Hash) (defaults to: {}) —

({})

Options Hash (params):

:model_id (required, String) —
The ID for the model.

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.

:messages (required, Array<Types::Message>) —

The messages that you want to send to the model.
:system (Array<Types::SystemContentBlock>) —

A system prompt to send to the model.
:inference_config (Types::InferenceConfiguration) —

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.
:tool_config (Types::ToolConfiguration) —
Configuration information for the tools that the model can use when generating a response.

<note markdown=“1”> This field is only supported by Anthropic Claude 3 models.
```
</note>
```
:additional_model_request_fields (Hash, Array, String, Numeric, Boolean) —

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

Document type used to carry open content (Hash,Array,String,Numeric,Boolean). A document type value is serialized using the same format as its surroundings and requires no additional encoding or escaping.
:additional_model_response_field_paths (Array<String>) —

Additional model parameters field paths to return in the response. ‘ConverseStream` returns the requested fields as a JSON Pointer object in the `additionalModelResultFields` 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`.

Examples:

EventStream Operation Example


You can process the event once it arrives immediately, or wait until the
full response is complete and iterate through the eventstream enumerator.

To interact with event immediately, you need to register #invoke_model_with_response_stream
with callbacks. Callbacks can be registered for specific events or for all
events, including error events.

Callbacks can be passed into the `:event_stream_handler` option or within a
block statement attached to the #invoke_model_with_response_stream call directly. Hybrid
pattern of both is also supported.

`:event_stream_handler` option takes in either a Proc object or
Aws::BedrockRuntime::EventStreams::ResponseStream object.

Usage pattern a): Callbacks with a block attached to #invoke_model_with_response_stream
  Example for registering callbacks for all event types and an error event

  client.invoke_model_with_response_stream( # params input# ) do |stream|
    stream.on_error_event do |event|
      # catch unmodeled error event in the stream
      raise event
      # => Aws::Errors::EventError
      # event.event_type => :error
      # event.error_code => String
      # event.error_message => String
    end

    stream.on_event do |event|
      # process all events arrive
      puts event.event_type
      ...
    end

  end

Usage pattern b): Pass in `:event_stream_handler` for #invoke_model_with_response_stream

  1) Create a Aws::BedrockRuntime::EventStreams::ResponseStream object
  Example for registering callbacks with specific events

    handler = Aws::BedrockRuntime::EventStreams::ResponseStream.new
    handler.on_chunk_event do |event|
      event # => Aws::BedrockRuntime::Types::chunk
    end
    handler.on_internal_server_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::internalServerException
    end
    handler.on_model_stream_error_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::modelStreamErrorException
    end
    handler.on_validation_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::validationException
    end
    handler.on_throttling_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::throttlingException
    end
    handler.on_model_timeout_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::modelTimeoutException
    end

  client.invoke_model_with_response_stream( # params input #, event_stream_handler: handler)

  2) Use a Ruby Proc object
  Example for registering callbacks with specific events

  handler = Proc.new do |stream|
    stream.on_chunk_event do |event|
      event # => Aws::BedrockRuntime::Types::chunk
    end
    stream.on_internal_server_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::internalServerException
    end
    stream.on_model_stream_error_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::modelStreamErrorException
    end
    stream.on_validation_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::validationException
    end
    stream.on_throttling_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::throttlingException
    end
    stream.on_model_timeout_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::modelTimeoutException
    end
  end

  client.invoke_model_with_response_stream( # params input #, event_stream_handler: handler)

Usage pattern c): Hybrid pattern of a) and b)

    handler = Aws::BedrockRuntime::EventStreams::ResponseStream.new
    handler.on_chunk_event do |event|
      event # => Aws::BedrockRuntime::Types::chunk
    end
    handler.on_internal_server_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::internalServerException
    end
    handler.on_model_stream_error_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::modelStreamErrorException
    end
    handler.on_validation_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::validationException
    end
    handler.on_throttling_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::throttlingException
    end
    handler.on_model_timeout_exception_event do |event|
      event # => Aws::BedrockRuntime::Types::modelTimeoutException
    end

  client.invoke_model_with_response_stream( # params input #, event_stream_handler: handler) do |stream|
    stream.on_error_event do |event|
      # catch unmodeled error event in the stream
      raise event
      # => Aws::Errors::EventError
      # event.event_type => :error
      # event.error_code => String
      # event.error_message => String
    end
  end

You can also iterate through events after the response complete.
