Overview

How can we enhance a model’s understanding of a query?

Re2 (Re-Reading) is a technique that asks the model to read the question again.

Re-Reading Prompting

Prompt Template:

  • Read the question again: {query}
  • {critical thinking prompt}

A common critical thinking prompt is: “Let’s think step by step.”

​
Example

<?php



$loader = require 'vendor/autoload.php';

$loader->add('Cognesy\\Instructor\\', __DIR__ . '../../src/');



use Cognesy\Instructor\Instructor;

use Cognesy\Instructor\Schema\Attributes\Description;



class Response {

    #[Description("Repeat user's query.")]

    public string $query;

    #[Description("Let's think step by step.")]

    public string $thoughts;

    public int $answer;

}



class RereadAndRespond {

    public function __invoke(string $query) : Response {

        return (new Instructor)->respond(

            messages: $query,

            responseModel: Response::class,

        );

    }

}



$response = (new RereadAndRespond)(

    query: <<<QUERY

        Each can has 3 tennis balls.
