Using CoT to improve interpretation of component data
Overview
You can reuse the same component for different contexts within a model. In this
example, the TimeRange component is used for both $workTime
and $leisureTime
.
We’re additionally starting the data structure with a Chain of Thought field to elicit LLM reasoning for the time range calculation, which can improve the accuracy of the response.
Example
<?php
$loader = require 'vendor/autoload.php';
$loader->add('Cognesy\\Instructor\\', __DIR__.'../../src/');
use Cognesy\Instructor\Instructor;
class TimeRange
{
/** Step by step reasoning to get the correct time range */
public string $chainOfThought;
/** The start time in hours (0-23 format) */
public int $startTime;
/** The end time in hours (0-23 format) */
public int $endTime;
}
$timeRange = (new Instructor)->respond(
messages: [['role' => 'user', 'content' => "Workshop with Apex Industries started 9 and it took us 6 hours to complete."]],
responseModel: TimeRange::class,
maxRetries: 2
);
dump($timeRange);
assert($timeRange->startTime === 9);
assert($timeRange->endTime === 15);
?>
