How to randomly display records from a table in Yii2?

Question

Yii

There is a site similar to a simple blog.
Entries from the database are displayed on the main feed of posts.
The problem is creating the "Also interesting on the topic" block (there are in all blogs on the side, links to other posts)
I don’t know how to randomly display records from the database
In the controller, I transfer all records from the database to the view

public function actionBlog()
    {
        $posts = Posts::find();
        $countQuery = clone $posts;
        $pages = new Pagination(['totalCount' => $countQuery->count(),
            'pageSize' => '2',]);
        $models = $posts->offset($pages->offset)
        ->limit($pages->limit)
        ->all();
        return $this->render('blog',[
           'models' => $models,
           'pages' => $pages,]);
    }

In the view, I catch all the records and output them to the tape like this

<?php foreach( $models as $post): ?>
                    <li>
                        <div class="post-content">
                            <a href="<?= Url::toRoute(['blogpost', 'id' => $post['post_id']]);?>" title=<?=$post['post_title']?> class="post-image">
                                <img src=<?='/acs/backend/web/'.$post['post_photo'];?> alt="" style="display: block;">
                            </a>

                            <h2 class="box-header align-left"><a href="<?= Url::toRoute(['blogpost', 'id' => $post['post_id']]);?>"><?=$post['post_title']?></a></h2>
                            <p class="description t1"><?=$post['post_brief']?></p>
                            <div class="row padding-top-54 padding-bottom-17">
                                <a class="more" href="<?= Url::toRoute(['blogpost', 'id' => $post['post_id']]);?>" title="Подробнее">Подробнее</a>
                            </div>
                        </div>
                    </li>
                <?php endforeach ;?>
                <?php echo LinkPager::widget(['pagination' => $pages,]);?>

->orderBy('RAND()') try when fetching models.
