After the resounding success of Laravel 11 with its "Slim Skeleton" structure, the community is focusing its attention on the next version: Laravel 12. Based on the development cycle and recent PRs (Pull Requests) on GitHub, here is a comprehensive look at what we can expect.

1. Release Roadmap & System Requirements

Laravel follows a Yearly Release Cycle. This gives development teams enough time to upgrade and maintain their applications.

Requiring a new PHP version allows Laravel to remove legacy code and leverage the most modern language features.

2. Leveraging PHP 8.4 Power: Property Hooks

PHP 8.4 introduces Property Hooks, a feature that completely changes how we write Getters and Setters. Laravel 12 will almost certainly deeply integrate this feature into Eloquent ORM.

Changes in Eloquent Accessors/Mutators

Instead of the verbose old syntax:

// Laravel 10/11 Way
protected function name(): Attribute
{
    return Attribute::make(
        get: fn (string $value) => ucfirst($value),
        set: fn (string $value) => strtolower($value),
    );
}

In Laravel 12 (on PHP 8.4), we can write it more cleanly directly on the property:

// Laravel 12 (Prediction)
public string $name {
    get => ucfirst($this->attributes['name']);
    set(string $value) => $this->attributes['name'] = strtolower($value);
}

This makes the Model cleaner, reduces reliance on magic methods, and improves code suggestion in IDEs (like PhpStorm).

3. Native AI Integration

Taylor Otwell (creator of Laravel) has repeatedly mentioned that AI will be an integral part. Laravel 12 might introduce First-party packages to work with LLMs (Large Language Models).

• ✔
  Vector Database Support: Native support for pgvector (PostgreSQL) or vector search solutions in Query Builder to build Semantic Search features.
• ✔
  AI Chain Facade: A unified API to call OpenAI, Claude, or Gemini without installing individual SDKs.

// Hypothetical example of AI Facade in Laravel 12
use Illuminate\Support\Facades\AI;

$summary = AI::model('gpt-4')
    ->prompt('Summarize this article provided in context')
    ->context($article->content)
    ->generate();

4. Performance Optimization with FrankenPHP

FrankenPHP is a modern application server for PHP built on Caddy. Laravel Octane already supports it, but Laravel 12 could make it a default choice or integrate it deeper for easier "Serverless" deployment.

5. The Ecosystem: Inertia 2.0 and Livewire 4

Laravel doesn't walk alone. Its development is tied to the Frontend.
