where i should write laravel eloquent query in laravel code example

Example 1: laravel list of models

 $path) {
            $models = array_merge(collect(File::allFiles(base_path($path)))
                ->map(function ($item) use ($namespace) {
                    $path = $item->getRelativePathName();
                    return sprintf('\%s%s',
                        $namespace,
                        strtr(substr($path, 0, strrpos($path, '.')), '/', '\\'));
                })
                ->filter(function ($class) {
                    $valid = false;
                    if (class_exists($class)) {
                        $reflection = new \ReflectionClass($class);
                        $valid = $reflection->isSubclassOf(\Illuminate\Database\Eloquent\Model::class) &&
                            !$reflection->isAbstract();
                    }
                    return $valid;
                })
                ->values()
                ->toArray(), $models);
        }
        return $models;
}

Example 2: laravel model::query

// Eloquent's Model::query() returns the query builder

Model::where()->get();
// Is the same as 
Model::query()->where()->get();

Model::query();
// Can be useful to add query conditions based on certain requirements
