# Laravel AI SDK

> Guida completa a Laravel AI SDK: interfaccia unificata per OpenAI, Anthropic, Gemini e altri provider. Agenti, immagini, audio, embedding e test.

## Introduzione

[Laravel AI SDK](https://github.com/laravel/ai) offre un'API unificata ed espressiva per interagire con provider AI come OpenAI, Anthropic, Gemini. Puoi costruire agenti intelligenti con tool e output strutturato, generare immagini, sintetizzare/trascrivere audio, creare embedding vettoriali — tutto con un'interfaccia coerente in stile Laravel.

<Info>
  Laravel AI SDK è il pacchetto ufficiale aggiunto in Laravel 13. Distribuito come `laravel/ai`, permette di usare più provider AI con la stessa API.

## Installazione

<Steps>
  <Step title="Installa il pacchetto">
    ```shell theme={null}
    composer require laravel/ai
    ```
  </Step>

  <Step title="Pubblica config e migration">
    ```shell theme={null}
    php artisan vendor:publish --provider="Laravel\Ai\AiServiceProvider"
    ```
  </Step>

  <Step title="Esegui le migration">
    Crea le tabelle `agent_conversations` e `agent_conversation_messages` per lo storico delle conversazioni.

    ```shell theme={null}
    php artisan migrate
    ```
  </Step>
</Steps>

## Configurazione

### Variabili d'ambiente

Configura le API key in `.env`:

```ini theme={null}
ANTHROPIC_API_KEY=
AZURE_OPENAI_API_KEY=
COHERE_API_KEY=
DEEPSEEK_API_KEY=
ELEVENLABS_API_KEY=
GEMINI_API_KEY=
GROQ_API_KEY=
MISTRAL_API_KEY=
OLLAMA_API_KEY=
OPENAI_API_KEY=
OPENROUTER_API_KEY=
JINA_API_KEY=
VOYAGEAI_API_KEY=
XAI_API_KEY=
```

I modelli predefiniti per testo, immagini, audio, trascrizione, embedding si impostano in `config/ai.php`.

### URL base personalizzato

Con proxy:

```php theme={null}
'providers' => [
    'openai' => [
        'driver' => 'openai',
        'key' => env('OPENAI_API_KEY'),
        'url' => env('OPENAI_URL'),
    ],
    'anthropic' => [
        'driver' => 'anthropic',
        'key' => env('ANTHROPIC_API_KEY'),
        'url' => env('ANTHROPIC_BASE_URL'),
    ],
],
```

Disponibile per OpenAI, Anthropic, Gemini, Groq, Cohere, DeepSeek, xAI, OpenRouter.

### Provider OpenAI-Compatible

Per LM Studio, vLLM, Together, Fireworks, gateway locali, usa il driver `openai-compatible`. `url` è obbligatorio; `key` viene inviata come Bearer token.

```php theme={null}
'providers' => [
    'local' => [
        'driver' => 'openai-compatible',
        'url' => env('LOCAL_AI_URL'),
        'key' => env('LOCAL_AI_API_KEY'),
    ],
],
```

Uso:

```php theme={null}
agent()->prompt('What is Laravel?', provider: 'local', model: 'local-model');
```

Con modello di default:

```php theme={null}
'local' => [
    'driver' => 'openai-compatible',
    'url' => env('LOCAL_AI_URL'),
    'key' => env('LOCAL_AI_API_KEY'),
    'models' => [
        'text' => [
            'default' => env('LOCAL_AI_MODEL'),
        ],
    ],
],
```

Supporta testo, streaming, tool, output strutturato, allegati immagine. Per campi aggiuntivi usa [Opzioni del provider](#opzioni-del-provider).

### Enum Lab

```php theme={null}
use Laravel\Ai\Enums\Lab;

Lab::Anthropic;
Lab::OpenAI;
Lab::Gemini;
```

***

## Agenti

Blocco di base dell'SDK. Crea con:

```shell theme={null}
php artisan make:agent SalesCoach

# Con output strutturato
php artisan make:agent SalesCoach --structured
```

In `app/Ai/Agents/`:

```php theme={null}
<?php

namespace App\Ai\Agents;

use App\Ai\Tools\RetrievePreviousTranscripts;
use App\Models\History;
use App\Models\User;
use Illuminate\Contracts\JsonSchema\JsonSchema;
use Laravel\Ai\Contracts\Agent;
use Laravel\Ai\Contracts\Conversational;
use Laravel\Ai\Contracts\HasStructuredOutput;
use Laravel\Ai\Contracts\HasTools;
use Laravel\Ai\Messages\Message;
use Laravel\Ai\Promptable;
use Stringable;

class SalesCoach implements Agent, Conversational, HasTools, HasStructuredOutput
{
    use Promptable;

    public function __construct(public User $user) {}

    public function instructions(): Stringable|string
    {
        return 'You are a sales coach, analyzing transcripts and providing feedback and an overall sales strength score.';
    }

    public function messages(): iterable
    {
        return History::where('user_id', $this->user->id)
            ->latest()
            ->limit(50)
            ->get()
            ->reverse()
            ->map(function ($message) {
                return new Message($message->role, $message->content);
            })->all();
    }

    public function tools(): iterable
    {
        return [new RetrievePreviousTranscripts];
    }

    public function schema(JsonSchema $schema): array
    {
        return [
            'feedback' => $schema->string()->required(),
            'score' => $schema->integer()->min(1)->max(10)->required(),
        ];
    }
}
```

```

### Prompt

```php theme={null}
$response = (new SalesCoach)->prompt('Analyze this sales transcript...');
return (string) $response;
```

`make()` statico usa il container:

```php theme={null}
$agent = SalesCoach::make(user: $user);
```

Override provider, modello, timeout:

```php theme={null}
$response = (new SalesCoach)->prompt(
    'Analyze this sales transcript...',
    provider: Lab::Anthropic,
    model: 'claude-haiku-4-5-20251001',
    timeout: 120,
);
```

### Contesto conversazionale

Implementando `Conversational` e definendo `messages()`, passi la cronologia al modello.

Con il trait `RemembersConversations` la persistenza avviene automaticamente su DB.

```php theme={null}
use Laravel\Ai\Concerns\RemembersConversations;

class SalesCoach implements Agent, Conversational
{
    use Promptable, RemembersConversations;

    public function instructions(): string
    {
        return 'You are a sales coach...';
    }
}
```

Con `forUser()` e `continue()`:

```php theme={null}
$response = (new SalesCoach)->forUser($user)->prompt('Hello!');
$conversationId = $response->conversationId;

$response = (new SalesCoach)->continue($conversationId, as: $user)->prompt('Tell me more about that.');
```

### Output strutturato

Con `HasStructuredOutput` e `schema()`:

```php theme={null}
public function schema(JsonSchema $schema): array
{
    return ['score' => $schema->integer()->required()];
}

$response = (new SalesCoach)->prompt('Analyze this...');
return $response['score'];
```

#### Oggetti annidati

```php theme={null}
public function schema(JsonSchema $schema): array
{
    return [
        'score' => $schema->integer()->required(),
        'metadata' => $schema->object(fn ($schema) => [
            'confidence' => $schema->string()->enum(['low', 'medium', 'high'])->required(),
            'language' => $schema->string()->required(),
        ])->required(),
    ];
}
```

#### Array di oggetti

```php theme={null}
public function schema(JsonSchema $schema): array
{
    return [
        'feedback' => $schema->array()->items(
            $schema->object(fn ($schema) => [
                'comment' => $schema->string()->required(),
                'score' => $schema->integer()->required(),
            ])
        )->required(),
    ];
}
```

#### anyOf

```php theme={null}
public function schema(JsonSchema $schema): array
{
    return [
        'content' => $schema->anyOf([
            $schema->object(fn ($schema) => [
                'type' => $schema->string()->enum(['article'])->required(),
                'title' => $schema->string()->required(),
            ]),
            $schema->object(fn ($schema) => [
                'type' => $schema->string()->enum(['image'])->required(),
                'url' => $schema->string()->required(),
            ]),
        ])->required(),
    ];
}
```

### Allegati

```php theme={null}
use Laravel\Ai\Files;

$response = (new SalesCoach)->prompt(
    'Analyze the attached sales transcript...',
    attachments: [
        Files\Document::fromStorage('transcript.pdf'),
        Files\Document::fromPath('/home/laravel/transcript.md'),
        $request->file('transcript'),
    ]
);
```

Immagini:

```php theme={null}
$response = (new ImageAnalyzer)->prompt('What is in this image?', attachments: [
    Files\Image::fromStorage('photo.jpg'),
    Files\Image::fromPath('/home/laravel/photo.jpg'),
    $request->file('photo'),
]);
```

### Streaming

```php theme={null}
Route::get('/coach', function () {
    return (new SalesCoach)->stream('Analyze this sales transcript...');
});
```

Callback finale con `then()`:

```php theme={null}
use Laravel\Ai\Responses\StreamedAgentResponse;

Route::get('/coach', function () {
    return (new SalesCoach)
        ->stream('Analyze this sales transcript...')
        ->then(function (StreamedAgentResponse $response) {
            // $response->text, $response->events, $response->usage...
        });
});
```

Iterazione manuale:

```php theme={null}
$stream = (new SalesCoach)->stream('Analyze this sales transcript...');

foreach ($stream as $event) {
    // ...
}
```

#### Protocollo Vercel AI SDK

```php theme={null}
Route::get('/coach', function () {
    return (new SalesCoach)->stream('Analyze...')->usingVercelDataProtocol();
});
```

### Broadcasting

```php theme={null}
use Illuminate\Broadcasting\Channel;

$stream = (new SalesCoach)->stream('Analyze this sales transcript...');

foreach ($stream as $event) {
    $event->broadcast(new Channel('channel-name'));
}
```

Via coda:

```php theme={null}
(new SalesCoach)->broadcastOnQueue(
    'Analyze this sales transcript...',
    new Channel('channel-name'),
);
```

#### Escludere eventi troppo grandi

Alcune piattaforme limitano i messaggi WebSocket (\~10KB). Con `WithoutBroadcasting` escludi eventi grandi.

```php theme={null}
<?php

namespace App\Ai\Agents;

use Laravel\Ai\Attributes\WithoutBroadcasting;
use Laravel\Ai\Contracts\Agent;
use Laravel\Ai\Contracts\HasTools;
use Laravel\Ai\Promptable;
use Laravel\Ai\Streaming\Events\ToolCall;
use Laravel\Ai\Streaming\Events\ToolResult;

#[WithoutBroadcasting(ToolCall::class, ToolResult::class)]
class SearchAgent implements Agent, HasTools
{
    use Promptable;
}
```

Il salvataggio in `agent_conversation_messages` continua: il frontend riceverà i dati completi al termine.

### Coda

```php theme={null}
use Laravel\Ai\Responses\AgentResponse;

Route::post('/coach', function (Request $request) {
    (new SalesCoach)
        ->queue($request->input('transcript'))
        ->then(function (AgentResponse $response) { /* ... */ })
        ->catch(function (Throwable $e) { /* ... */ });

    return back();
});
```

### Tool

I tool consentono all'AI di chiamare funzioni del tuo codice.

```shell theme={null}
php artisan make:tool RandomNumberGenerator
```

```php theme={null}
<?php

namespace App\Ai\Tools;

use Illuminate\Contracts\JsonSchema\JsonSchema;
use Laravel\Ai\Contracts\Tool;
use Laravel\Ai\Tools\Request;
use Stringable;

class RandomNumberGenerator implements Tool
{
    public function description(): Stringable|string
    {
        return 'This tool may be used to generate cryptographically secure random numbers.';
    }

    public function handle(Request $request): Stringable|string
    {
        return (string) random_int($request['min'], $request['max']);
    }

    public function schema(JsonSchema $schema): array
    {
        return [
            'min' => $schema->integer()->min(0)->required(),
            'max' => $schema->integer()->required(),
        ];
    }
}
```

Registrazione:

```php theme={null}
public function tools(): iterable
{
    return [new RandomNumberGenerator];
}
```

#### Tool di ricerca per similarità

```php theme={null}
use App\Models\Document;
use Laravel\Ai\Tools\SimilaritySearch;

public function tools(): iterable
{
    return [
        SimilaritySearch::usingModel(Document::class, 'embedding'),
    ];
}
```

Con opzioni:

```php theme={null}
SimilaritySearch::usingModel(
    model: Document::class,
    column: 'embedding',
    minSimilarity: 0.7,
    limit: 10,
    query: fn ($query) => $query->where('published', true),
),
```

Con closure:

```php theme={null}
new SimilaritySearch(using: function (string $query) {
    return Document::query()
        ->where('user_id', $this->user->id)
        ->whereVectorSimilarTo('embedding', $query)
        ->limit(10)
        ->get();
}),
```

Descrizione custom:

```php theme={null}
SimilaritySearch::usingModel(Document::class, 'embedding')
    ->withDescription('Search the knowledge base for relevant articles.'),
```

### Tool di file storage

Con `FileStorage` dai all'agente accesso ai [disk](/it/filesystem).

```php theme={null}
use Laravel\Ai\Tools\FileStorage;

public function tools(): iterable
{
    return FileStorage::all('local');
}
```

Sola lettura:

```php theme={null}
return FileStorage::readOnly('local');
```

Puoi filtrare il set (restituisce `Illuminate\Support\Collection`):

```php theme={null}
use Laravel\Ai\Tools\Filesystem\DeleteFile;

return FileStorage::all('s3')
    ->reject(fn ($tool) => $tool instanceof DeleteFile);
```

### Tool MCP

Se usi [Laravel MCP](/it/mcp), esponi all'agente i tool di server MCP.

<Info>
  Richiede il pacchetto [Laravel MCP](/it/mcp).
</Info>

```php theme={null}
use App\Ai\Tools\RandomNumberGenerator;
use Laravel\Mcp\Client;

public function tools(): iterable
{
    return [
        ...Client::web('https://mcp.example.com')
            ->withToken($token)
            ->tools(),

        new RandomNumberGenerator,
    ];
}
```

Client con nome:

```php theme={null}
use Laravel\Mcp\Facades\Mcp;

public function tools(): iterable
{
    return [
        ...Mcp::client('github')->tools(),
    ];
}
```

Locale:

```php theme={null}
use Laravel\Mcp\Client;

public function tools(): iterable
{
    return [
        ...Client::local('php', ['artisan', 'mcp:start'])->tools(),
    ];
}
```

Vedi la [documentazione MCP](/it/mcp#mcp-client) per creazione e autenticazione.

### Tool nativi del provider

#### Web search

Anthropic, OpenAI, Gemini, OpenRouter.

```php theme={null}
use Laravel\Ai\Providers\Tools\WebSearch;

public function tools(): iterable
{
    return [new WebSearch];
}
```

```php theme={null}
(new WebSearch)->max(5)->allow(['laravel.com', 'php.net']),
(new WebSearch)->location(city: 'New York', region: 'NY', country: 'US');
```

#### Web fetch

Anthropic, Gemini.

```php theme={null}
use Laravel\Ai\Providers\Tools\WebFetch;

public function tools(): iterable
{
    return [new WebFetch];
}

(new WebFetch)->max(3)->allow(['docs.laravel.com']),
```

#### File search

OpenAI, Gemini.

```php theme={null}
use Laravel\Ai\Providers\Tools\FileSearch;

public function tools(): iterable
{
    return [new FileSearch(stores: ['store_id'])];
}

new FileSearch(stores: ['store_1', 'store_2']);

new FileSearch(stores: ['store_id'], where: ['author' => 'Taylor Otwell', 'year' => 2026]);
```

Filtri complessi:

```php theme={null}
use Laravel\Ai\Providers\Tools\FileSearchQuery;

new FileSearch(stores: ['store_id'], where: fn (FileSearchQuery $query) =>
    $query->where('author', 'Taylor Otwell')
          ->whereNot('status', 'draft')
          ->whereIn('category', ['news', 'updates'])
);
```

### Sub-agenti

Un agente può esporre altri agenti come tool.

```php theme={null}
<?php

namespace App\Ai\Agents;

use Laravel\Ai\Contracts\Agent;
use Laravel\Ai\Contracts\HasTools;
use Laravel\Ai\Promptable;

class CustomerSupportAgent implements Agent, HasTools
{
    use Promptable;

    public function instructions(): string
    {
        return 'You help customers with account, order, and billing questions. Delegate refund policy questions to the refunds specialist.';
    }

    public function tools(): iterable
    {
        return [
            new RefundsAgent,
        ];
    }
}
```

Con `CanActAsTool` personalizzi il nome/descrizione:

```php theme={null}
<?php

namespace App\Ai\Agents;

use App\Ai\Tools\LookupOrder;
use Laravel\Ai\Attributes\Provider;
use Laravel\Ai\Contracts\Agent;
use Laravel\Ai\Contracts\CanActAsTool;
use Laravel\Ai\Contracts\HasTools;
use Laravel\Ai\Enums\Lab;
use Laravel\Ai\Promptable;

#[Provider(Lab::Anthropic)]
class RefundsAgent implements Agent, CanActAsTool, HasTools
{
    use Promptable;

    public function instructions(): string
    {
        return 'You are a refunds specialist. Use order details and the refund policy to give concise eligibility guidance.';
    }

    public function name(): string
    {
        return 'refunds_specialist';
    }

    public function description(): string
    {
        return 'Determine whether an order is eligible for a refund and explain the next step.';
    }

    public function tools(): iterable
    {
        return [
            new LookupOrder,
        ];
    }
}
```

Senza `CanActAsTool`, Laravel usa il nome della classe e una descrizione generica. Ogni chiamata al sub-agente è indipendente.

### Middleware

```shell theme={null}
php artisan make:agent-middleware LogPrompts
```

```php theme={null}
<?php

namespace App\Ai\Agents;

use App\Ai\Middleware\LogPrompts;
use Laravel\Ai\Contracts\Agent;
use Laravel\Ai\Contracts\HasMiddleware;
use Laravel\Ai\Promptable;

class SalesCoach implements Agent, HasMiddleware
{
    use Promptable;

    public function middleware(): array
    {
        return [new LogPrompts];
    }
}
```

```php theme={null}
<?php

namespace App\Ai\Middleware;

use Closure;
use Laravel\Ai\Prompts\AgentPrompt;

class LogPrompts
{
    public function handle(AgentPrompt $prompt, Closure $next)
    {
        Log::info('Prompting agent', ['prompt' => $prompt->prompt]);
        return $next($prompt);
    }
}
```

Con `then()`:

```php theme={null}
public function handle(AgentPrompt $prompt, Closure $next)
{
    return $next($prompt)->then(function (AgentResponse $response) {
        Log::info('Agent responded', ['text' => $response->text]);
    });
}
```

### Agenti anonimi

```php theme={null}
use function Laravel\Ai\{agent};

$response = agent(
    instructions: 'You are an expert at software development.',
    messages: [],
    tools: [],
)->prompt('Tell me about Laravel');
```

Con output strutturato:

```php theme={null}
use Illuminate\Contracts\JsonSchema\JsonSchema;

$response = agent(
    schema: fn (JsonSchema $schema) => ['number' => $schema->integer()->required()],
)->prompt('Generate a random number less than 100');
```

        $table->timestamps();
    });

    $table->vector('embedding', dimensions: 1536)->index();
    ```
  </Step>

  <Step title="Modello">
    ```php theme={null}
    protected function casts(): array
    {
        return ['embedding' => 'array'];
    }
    ```
  </Step>

  <Step title="Query per similarità">
    ```php theme={null}
    $documents = Document::query()
        ->whereVectorSimilarTo('embedding', $queryEmbedding, minSimilarity: 0.4)

## Test

### Agent

```php theme={null}
use App\Ai\Agents\SalesCoach;
use Laravel\Ai\Prompts\AgentPrompt;

SalesCoach::fake();
SalesCoach::fake(['First response', 'Second response']);

SalesCoach::fake(function (AgentPrompt $prompt) {
    return 'Response for: '.$prompt->prompt;
});

SalesCoach::assertPrompted('Analyze this...');
SalesCoach::assertPrompted(function (AgentPrompt $prompt) {
    return $prompt->contains('Analyze');
});
SalesCoach::assertNotPrompted('Missing prompt');
SalesCoach::assertNeverPrompted();
```

Code:

```php theme={null}
use Laravel\Ai\QueuedAgentPrompt;

SalesCoach::assertQueued('Analyze this...');
SalesCoach::assertQueued(function (QueuedAgentPrompt $prompt) {
    return $prompt->contains('Analyze');
});
SalesCoach::assertNotQueued('Missing prompt');
SalesCoach::assertNeverQueued();
```

Prevenire prompt non fake:

```php theme={null}
SalesCoach::fake()->preventStrayPrompts();
```
