Reusing components
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
.
Example
Copy
<?php
require 'examples/boot.php';
use Cognesy\Instructor\Instructor;
class TimeRange {
/** The start time in hours. */
public int $startTime;
/** The end time in hours. */
public int $endTime;
}
class UserDetail
{
public string $name;
/** Time range during which the user is working. */
public TimeRange $workTime;
/** Time range reserved for leisure activities. */
public TimeRange $leisureTime;
}
$user = (new Instructor)->respond(
messages: [['role' => 'user', 'content' => "Yesterday Jason worked from 9 for 5 hours. After that I watched 2 hour movie which I finished at 19."]],
responseModel: UserDetail::class,
model: 'gpt-4o',
);
dump($user);
assert($user->name == "Jason");
assert($user->workTime->startTime === 9);
assert($user->workTime->endTime === 14);
assert($user->leisureTime->startTime === 17);
assert($user->leisureTime->endTime === 19);
?>
