require_once(ABSPATH . "wp-admin" . '/includes/image.php');

well i look and i look and finally i found this work that work for me.

    $upload = wp_upload_bits( $_FILES['image']['name'], null, file_get_contents( $_FILES['image']['tmp_name'] ) );

    $wp_filetype = wp_check_filetype( basename( $upload['file'] ), null );

    $wp_upload_dir = wp_upload_dir();

    $attachment = array(
        'guid' => $wp_upload_dir['baseurl'] . _wp_relative_upload_path( $upload['file'] ),
        'post_mime_type' => $wp_filetype['type'],
        'post_title' => preg_replace('/\.[^.]+$/', '', basename( $upload['file'] )),
        'post_content' => '',
        'post_status' => 'inherit'
    );

    $attach_id = wp_insert_attachment( $attachment, $upload['file'], $post_id );

    require_once(ABSPATH . 'wp-admin/includes/image.php');

    $attach_data = wp_generate_attachment_metadata( $attach_id, $upload['file'] );
    wp_update_attachment_metadata( $attach_id, $attach_data );

    update_post_meta( $post_id, '_thumbnail_id', $attach_id );

    wp_redirect( site_url() . '/thank-you/' );

    die();
}
