Overview

Builds and returns a payload hash suitable for the Amazon model processing. This method constructs a payload with specific parameters like ‘model_id`, `content_type`, `accept`, and a `body` that includes various AI-related settings.

Returns:

  • (Hash) —

    The constructed payload containing AI model parameters and settings.

Instance Method Details

#build ⇒ Hash

Builds and returns a hash representing the payload for a text generation request. This method prepares the necessary data structure for processing an input text through a specified model. It includes various configuration parameters for text generation.

Returns:

  • (Hash) —

    The method returns a hash with the following key-value pairs:

    • :model_id [String] The identifier for the model that will process the request.

    • :content_type [String] Specifies the content type of the payload, set to ‘application/json’.

    • :accept [String] Indicates the MIME type that the response should conform to.

    • :body [String] A JSON string that includes the following details:

      • :inputText [String] The input text to be processed by the model.

      • :textGenerationConfig [Hash] A hash containing configuration parameters for text generation:

        • :maxTokens [Integer] The maximum number of tokens to generate.

        • :stopSequences [Array<String>] An array of strings that, when encountered, will signal the end

    of generation.

    - :temperature [Float] A parameter controlling the randomness in the response generation.
- :topP [Float] A parameter controlling the diversity of the generated text.
