Ai Albert Platform Laravel Package

// services.php
$app->bind(\Symfony\Component\AI\Provider\AiProviderInterface::class, \Symfony\Component\AI\Provider\AlbertProvider::class);
```                                                                                                                                                                                                                   |
| **HTTP Client**             | Use Laravel’s **Guzzle client** or Symfony’s `HttpClient` (injected via the package). No additional setup required if using `symfony/ai`.                                                                                     |
| **Queues**                  | Offload AI calls to **Laravel queues** (e.g., `bus:dispatch`) for async processing. Example:                                                                                                                                 |
|                             | ```php                                                                                                                                                                                                                   |
|                             | use Symfony\Component\AI\Client;
|                             | use Illuminate\Bus\Queueable;
|
|                             | class GenerateEmbedding implements ShouldQueue {
|                             |     use Queueable;
|
|                             |     public function handle(Client $aiClient) {
|                             |         $embeddings = $aiClient->embeddings(['text' => 'sample']);
|                             |         // Save to DB or cache
|                             |     }
|                             | }
|                             | ```                                                                                                                                                                                                                   |
| **Caching**                 | Cache embeddings or frequent API responses using Laravel’s cache (e.g., Redis). Example:                                                                                                                                 |
|                             | ```php                                                                                                                                                                                                                   |
|                             | $embeddings = Cache::remember('embeddings:sample', now()->addHours(1), function () use ($aiClient) {
|                             |     return $aiClient->embeddings(['text' => 'sample']);
|                             | });
|                             | ```                                                                                                                                                                                                                   |
| **Routing**                 | Use Laravel’s **middleware** or **service providers** to route requests based on business logic (e.g., cost vs. quality). Example:                                                                                     |
|                             | ```php                                                                                                                                                                                                                   |
|                             | // app/Providers/AiServiceProvider.php
|                             | public function register() {
|                             |     $this->app->bind(AiProviderInterface::class, function ($app) {

|                             |         }
|                             |         return new OpenAiProvider($app['config']['ai.openai_api_key']);
|                             |     });
|                             | }
|                             | ```                                                                                                                                                                                                                   |
| **Validation**              | Validate AI inputs/outputs using Laravel’s **Form Requests** or **Pipes**. Example:                                                                                                                                 |
|                             | ```php                                                                                                                                                                                                                   |

|                             | }
|                             | ```                                                                                                                                                                                                                   |
| **Events**                  | Dispatch events for AI responses (e.g., `AiResponseGenerated`) to trigger side effects (e.g., logging, analytics). Example:                                                                                     |

|                             |         ->once()
|                             |         ->andReturn(['choices' => [['text' => 'mocked response']]]);
|                             | });
|                             | ```                                                                                                                                                                                                                   |
| **Monitoring**              | Log AI calls using Laravel’s **logging** or **Sentry**. Example:                                                                                                                                                             |
|                             | ```php                                                                                                                                                                                                                   |

Step-by-Step Implementation Plan

1. Assess Compatibility

   • Verify Laravel’s PHP version supports symfony/ai (e.g., PHP 8.1+).
   • Check for conflicts with existing symfony/* packages.

2. Install Dependencies

   composer require symfony/ai symfony/ai-albert-platform
   

3. Configure the Provider

   • Add Albert’s API key to .env:

     ALBERT_API_KEY=your_api_key_here
     

   • Configure the provider in config/ai.php:

     'providers' => [
         'default' => \Symfony\Component\AI\Provider\AlbertProvider::class,
         'fallback' => \Symfony\Component\AI\Provider\OpenAiProvider::class,
     ],
     'albert' => [
         'api_key' => env('ALBERT_API_KEY'),
         'endpoint' => 'https://albert.api.etalab.gouv.fr',
     ],
     

4. Implement Provider Abstraction

   • Extend the AiProviderInterface to support dynamic routing:

     use Symfony\Component\AI\Provider\AiProviderInterface;
     
     class CustomAiProvider implements AiProviderInterface {
         private $providers;
     
         public function __construct(array $providers) {
             $this->providers = $providers;
         }
     
         public function complete(array $options) {
             foreach ($this->providers as $provider) {
                 try {
                     return $provider->complete($options);
                 } catch (\Exception $e) {
                     continue; // Fallback to next provider
                 }
             }
             throw new \RuntimeException('All AI providers failed');
         }
     }
     

5. Integrate with Laravel Services

   • Bind the provider in a service provider:

     $this->app->bind(AiProviderInterface::class, function ($app) {
         return new CustomAiProvider([
             new AlbertProvider($app['config']['ai.albert']),
             new OpenAiProvider($app['config']['ai.openai']),
         ]);
     });
     

6. Build Use Case-Specific Features

   • Chatbot:

     use Symfony\Component\AI\Client;
     
     public function handleChatRequest(string $prompt) {
         $ai = app(Client::class);
         $response = $ai->complete(['prompt' => $prompt, 'model' => 'mistral-7b']);
         return $response['choices'][0]['text'];
     }
     

   • Semantic Search:

     public function generateEmbedding(string $text) {
         $ai = app(Client::class);
         $embedding = $ai->embeddings(['text' => $text, 'model' => 'all-minilm']);
         return $embedding['data'][0]['embedding'];
     }
     

7. Add Error Handling and Retries

   • Use Laravel’s Spatie/Fluent for retries or custom middleware:

     use Symfony\Component\AI\Exception\AiException;
     use Illuminate\Http\Request;
     use Illuminate\Routing\Middleware;
     
     public function handle(Request $request, Closure $next) {
         try {
             return $next($request);
         } catch (AiException $e) {
             // Fallback logic or return cached response
             return response()->json(['error' => 'AI service unavailable'], 503);
         }
     }
     

8. Test and Benchmark

   • Write unit/integration tests for provider abstraction.
   • Benchmark latency/cost against OpenAI using Laravel’s benchmark() helper:

     $time = benchmark(function () {
         $ai->complete(['prompt' => 'benchmark']);
     });
     

9. Deploy and Monitor

   • Roll out in stages (e.g., non-critical features first).
   • Monitor latency, cost, and error rates via Laravel’s logging or third-party tools (e.g., Datadog).

## Risks and Mitigations
| **Risk**                          | **Impact**                          | **Mitigation**                                                                                                                                                                                                 |
|-----------------------------------|-------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| **Limited Model Variety**        | Fewer models than OpenAI/HF.       | Use **model routing** to prioritize available models (e.g., `mistral-7b` for cost, `llama-2` for quality)
