Overview

Builds and returns a payload hash suitable for the Meta 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

Constructs and returns a payload formatted for text generation requests. This method assembles the necessary data structure for processing text input through an AI model, with various parameters to guide the generation process.

Returns:

  • (Hash) —

    A structured payload containing:

    • :model_id [String] Identifier for the AI model that will process the text generation request.

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

    • :accept [String] Indicates the MIME type for the expected response.

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

      • :prompt [String] The input text for the model to generate content from.

      • :max_gen_len [Integer] Maximum length for the generated content, measured in tokens.

      • :temperature [Float] A parameter controlling the randomness in the generated content.

      • :top_p [Float] Nucleus sampling parameter controlling the diversity of the generated text.
