# Developing with the Laravel AI SDK

The Laravel AI SDK (`laravel/ai`) is the official AI package for Laravel, providing a unified API for agents, images, audio, transcription, embeddings, reranking, vector stores, and file management across multiple AI providers.

## Searching the Documentation

This package is new. Always search the documentation before implementing any feature. Never guess at APIs — the documentation is the single source of truth.

- Use broad, simple queries that match the documentation section headings below.
- Do not add package names to queries — package information is shared automatically. Use `test agent fake`, not `laravel ai test agent fake`.
- Run multiple queries at once — the most relevant results are returned first.

### Documentation Sections

Use these section headings as query terms for accurate results:

- Introduction, Installation, Configuration, Provider Support
- Agents: Prompting, Conversation Context, Structured Output, Attachments, Streaming, Broadcasting, Queueing, Tools, Provider Tools, Middleware, Anonymous Agents, Agent Configuration
- Images
- Audio (TTS)
- Transcription (STT)
- Embeddings: Querying Embeddings, Caching Embeddings
- Reranking
- Files
- Vector Stores: Adding Files to Stores
- Failover
- Testing: Agents, Images, Audio, Transcriptions, Embeddings, Reranking, Files, Vector Stores
- Events

## Decision Workflow

Determine the right entry point before writing code:

Text generation or chat? → Agent class with `Promptable` trait
Chat with conversation history? → Agent + `Conversational` interface (manual) or `RemembersConversations` trait (automatic)
Structured JSON output? → Agent + `HasStructuredOutput` interface
Image generation? → `Image::of()->generate()`
Audio synthesis? → `Audio::of()->generate()`
Transcription? → `Transcription::fromPath()->generate()`
Embeddings? → `Embeddings::for()->generate()`
Reranking? → `Reranking::of()->rerank()`
File storage? → `Document::fromPath()->put()`
Vector stores? → `Stores::create()`

## Basic Usage Examples

### Agents

```php
use Laravel\Ai\Contracts\Agent;
use Laravel\Ai\Enums\Lab;
use Laravel\Ai\Promptable;

class SalesCoach implements Agent
{
    use Promptable;

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

// Prompting
$response = (new SalesCoach)->prompt('Analyze this transcript...');
echo $response->text;

// Container resolution with dependency injection
$agent = SalesCoach::make(user: $user);

// Override provider, model, or timeout per-prompt
$response = (new SalesCoach)->prompt(
    'Analyze this transcript...',
    provider: Lab::Anthropic,
    model: 'claude-haiku-4-5-20251001',
    timeout: 120,
);

// Streaming (returns SSE response from a route)
return (new SalesCoach)->stream('Analyze this transcript...');

// Queueing
(new SalesCoach)->queue('Analyze this transcript...')
    ->then(fn ($response) => /* ... */);

// Anonymous agents
use function Laravel\Ai\{agent};

$response = agent(instructions: 'You are a helpful assistant.')->prompt('Hello');
```

### Conversation Context

Manual conversation history via the `Conversational` interface:

```php
use Laravel\Ai\Contracts\Agent;
use Laravel\Ai\Contracts\Conversational;
use Laravel\Ai\Messages\Message;
use Laravel\Ai\Promptable;

class SalesCoach implements Agent, Conversational
{
    use Promptable;

    public function __construct(public User $user) {}

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

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

Automatic conversation persistence via the `RemembersConversations` trait:

```php
use Laravel\Ai\Concerns\RemembersConversations;
use Laravel\Ai\Contracts\Agent;
use Laravel\Ai\Contracts\Conversational;
use Laravel\Ai\Promptable;

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

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

// Start a new conversation
$response = (new SalesCoach)->forUser($user)->prompt('Hello!');
$conversationId = $response->conversationId;

// Continue an existing conversation
$response = (new SalesCoach)->continue($conversationId, as: $user)->prompt('Tell me more.');
```

### Structured Output

```php
use Illuminate\Contracts\JsonSchema\JsonSchema;
use Laravel\Ai\Contracts\Agent;
use Laravel\Ai\Contracts\HasStructuredOutput;
use Laravel\Ai\Promptable;

class Reviewer implements Agent, HasStructuredOutput
{
    use Promptable;

    public function instructions(): string { return 'Review and score content.'; }

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

$response = (new Reviewer)->prompt('Review this...');
echo $response['score']; // Access like an array
```

### Images

```php
use Laravel\Ai\Image;

$image = Image::of('A sunset over mountains')
    ->landscape()
    ->quality('high')
    ->generate();

$path = $image->store(); // Store to default disk
```

### Audio

```php
use Laravel\Ai\Audio;

$audio = Audio::of('Hello from Laravel.')
    ->female()
    ->instructions('Speak warmly')
    ->generate();

$path = $audio->store();
```

### Transcription

```php
use Laravel\Ai\Transcription;

$transcript = Transcription::fromStorage('audio.mp3')
    ->diarize()
    ->generate();

echo (string) $transcript;
```

### Embeddings

```php
use Laravel\Ai\Embeddings;
use Illuminate\Support\Str;

$response = Embeddings::for(['Text one', 'Text two'])
    ->dimensions(1536)
    ->cache()
    ->generate();

// Single string via Stringable
$embedding = Str::of('Napa Valley has great wine.')->toEmbeddings();
```

### Reranking

```php
use Laravel\Ai\Reranking;

$response = Reranking::of(['Django is Python.', 'Laravel is PHP.', 'React is JS.'])
    ->limit(5)
    ->rerank('PHP frameworks');

$response->first()->document; // "Laravel is PHP."
```

### Files and Vector Stores

```php
use Laravel\Ai\Files\Document;
use Laravel\Ai\Stores;

// Store a file with the provider
$file = Document::fromPath('/path/to/doc.pdf')->put();

// Create a vector store and add files
$store = Stores::create('Knowledge Base');
$store->add($file->id);
$store->add(Document::fromStorage('manual.pdf')); // Store + add in one step
```

## Agent Configuration

### PHP Attributes

```php
use Laravel\Ai\Attributes\{Provider, Model, MaxSteps, MaxTokens, Temperature, Timeout};
use Laravel\Ai\Enums\Lab;

#[Provider(Lab::Anthropic)]
#[Model('claude-haiku-4-5-20251001')]
#[MaxSteps(10)]
#[MaxTokens(4096)]
#[Temperature(0.7)]
#[Timeout(120)]
class MyAgent implements Agent
{
    use Promptable;
    // ...
}
```

The `#[UseCheapestModel]` and `#[UseSmartestModel]` attributes are also available for automatic model selection.

Use `#[RepairToolCalls]` to let an agent recover when a model calls an unknown local tool. The failed call is returned to the model with the available local tool names, and the implicit step budget includes one repair step. Explicit `#[MaxSteps]` limits remain unchanged.

```php
use Laravel\Ai\Attributes\RepairToolCalls;

#[RepairToolCalls]
class SupportAgent implements Agent, HasTools
{
    use Promptable;

    // ...
}
```

The `#[WithoutBroadcasting]` attribute stops the given stream event types from broadcasting (e.g. data-heavy `ToolResult` payloads that exceed the WebSocket frame limit). The events are still streamed and persisted; they just never hit the channel:

```php
use Laravel\Ai\Attributes\WithoutBroadcasting;
use Laravel\Ai\Streaming\Events\{ToolCall, ToolResult};

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

### Tools

Implement the `HasTools` interface and scaffold tools with `php artisan make:tool`:

```php
use Laravel\Ai\Contracts\HasTools;

class MyAgent implements Agent, HasTools
{
    use Promptable;

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

### Provider Tools

```php
use Laravel\Ai\Providers\Tools\{WebSearch, WebFetch, FileSearch};

public function tools(): iterable
{
    return [
        (new WebSearch)->max(5)->allow(['laravel.com']),
        new WebFetch,
        new FileSearch(stores: ['store_id']),
    ];
}
```

### MCP Servers

Register the server once, then return its tools from `tools()`. The SDK automatically wraps each `Laravel\Mcp\Client\Primitives\Tool` and presents it to the model as `mcp_tools_<name>`. Return your own `Laravel\Mcp\Server\Tool` instances in the same way and they retain their names and run in-process.

```php
use Laravel\Mcp\Client;
use Laravel\Mcp\Facades\Mcp;

// In a service provider or routes/ai.php
Mcp::registerClient('linear', fn () => Client::web('https://mcp.linear.app/mcp')
    ->withToken(config('services.linear.token')));

class SupportAgent implements Agent, HasTools
{
    use Promptable;

    public function tools(): iterable
    {
        return Mcp::client('linear')->tools();
    }
}
```

The client connects on its first call, so call `connect()` only when you need to control the timing. Use `Client::local('npx', ['-y', 'some-server'])` for servers that run over stdio.

### Conversation Memory

```php
use Laravel\Ai\Concerns\RemembersConversations;
use Laravel\Ai\Contracts\Conversational;

class ChatBot implements Agent, Conversational
{
    use Promptable, RemembersConversations;
    // ...
}

$response = (new ChatBot)->forUser($user)->prompt('Hello!');
$response = (new ChatBot)->continue($conversationId, as: $user)->prompt('More...');
```

### Failover

```php
$response = (new MyAgent)->prompt('Hello', provider: [Lab::OpenAI, Lab::Anthropic]);
```

## Testing and Faking

Each capability supports `fake()` with assertions:

```php
use App\Ai\Agents\SalesCoach;
use Laravel\Ai\{Image, Audio, Transcription, Embeddings, Reranking, Files, Stores};

// Agents
SalesCoach::fake(['Response 1', 'Response 2']);
SalesCoach::assertPrompted('query');
SalesCoach::assertNotPrompted('query');
SalesCoach::assertNeverPrompted();
SalesCoach::fake()->preventStrayPrompts();

// Images
Image::fake();
Image::assertGenerated(fn ($prompt) => $prompt->contains('sunset'));
Image::assertNothingGenerated();

// Audio
Audio::fake();
Audio::assertGenerated(fn ($prompt) => $prompt->contains('Hello'));

// Transcription
Transcription::fake(['Transcribed text.']);
Transcription::assertGenerated(fn ($prompt) => $prompt->isDiarized());

// Embeddings
Embeddings::fake();
Embeddings::assertGenerated(fn ($prompt) => $prompt->contains('Laravel'));

// Reranking
Reranking::fake();
Reranking::assertReranked(fn ($prompt) => $prompt->contains('PHP'));

// Files
Files::fake();
Files::assertStored(fn ($file) => $file->mimeType() === 'text/plain');

// Stores
Stores::fake();
Stores::assertCreated('Knowledge Base');
$store = Stores::get('id');
$store->assertAdded('file_id');
```

## Key Patterns

- Namespace: `Laravel\Ai\`
- Package: `composer require laravel/ai`
- Agent pattern: Implement the `Agent` interface and use the `Promptable` trait
- Optional interfaces: `HasTools`, `HasMiddleware`, `HasStructuredOutput`, `Conversational`
- Entry-point classes: `Image`, `Audio`, `Transcription`, `Embeddings`, `Reranking`, `Stores`
- Provider enum: `Laravel\Ai\Enums\Lab` (prefer over plain strings)
- Artisan commands: `php artisan make:agent`, `php artisan make:tool`
- Global helper: `agent()` for anonymous agents

## OpenAI-Compatible Provider

Point the SDK at any OpenAI-compatible endpoint (LM Studio, vLLM, Together, etc.) with the config-driven `openai-compatible` driver. Define named instances in `config/ai.php`, no code required:

```php
'my-llm' => [
    'driver' => 'openai-compatible',
    'url' => env('MY_LLM_URL'),        // required
    'key' => env('MY_LLM_API_KEY'),    // optional Bearer token
    'models' => [
        'text' => ['default' => 'some-chat-model'],
        'embeddings' => [
            'default' => 'some-embedding-model',
            'dimensions' => 1024, // optional; omit to use native dimensions
        ],
        'transcription' => ['default' => 'some-transcription-model'],
    ],
],
```

Reference it by config key (or `Lab::OpenAiCompatible`). A model is required via the corresponding `models` configuration or per-call `model:`:

```php
agent()->prompt('Hello', provider: 'my-llm', model: 'some-model');

Embeddings::for(['Hello'])->generate(
    provider: 'my-llm',
    model: 'some-embedding-model',
);
```

It uses OpenAI-standard shapes and supports text, streaming, tools, structured output, image attachments, text embeddings, and audio transcription. Embedding dimensions are optional; omit them to use the model's native dimensions. For extra request-body fields, implement `HasProviderOptions` — the returned array is merged into the body.

Transcription uploads standard multipart (`file` + `model` + optional `language`) and defaults to `response_format: json`. Because endpoints vary, provider options override the defaults — pass `response_format: 'verbose_json'` for segments, or use `diarize()` on servers that implement `diarized_json`:

```php
Transcription::fromDisk('recordings', $path)
    ->withProviderOptions(['response_format' => 'verbose_json'])
    ->generate(provider: 'my-llm');
```

## Common Pitfalls

### Wrong Namespace

The namespace is `Laravel\Ai`, not `Illuminate\Ai` or `Laravel\AI`.

```php
// Correct
use Laravel\Ai\Image;
use Laravel\Ai\Contracts\Agent;
use Laravel\Ai\Promptable;

// Wrong — these do not exist
use Illuminate\Ai\Image;
use Laravel\AI\Agent;
```

### Unsupported Provider Capability

Calling a capability not supported by a provider throws a `LogicException`. Refer to the provider support table below.

## Provider Support

| Feature    | Providers                                                       |
| ---------- | --------------------------------------------------------------- |
| Text       | OpenAI, Anthropic, Gemini, Azure, Groq, xAI, DeepSeek, Mistral, Ollama, OpenRouter, OpenAI-compatible |
| Images     | OpenAI, Gemini, xAI                                            |
| TTS        | OpenAI, ElevenLabs, Mistral                                     |
| STT        | OpenAI, ElevenLabs, Mistral, Groq, OpenAI-compatible            |
| Embeddings | OpenAI, OpenAI-compatible, Gemini, Azure, Cohere, Mistral, Jina, VoyageAI |
| Reranking  | Cohere, Jina                                                    |
| Files      | OpenAI, Anthropic, Gemini                                       |

Use the `Laravel\Ai\Enums\Lab` enum to reference providers in code instead of plain strings:

```php
use Laravel\Ai\Enums\Lab;

Lab::Anthropic;
Lab::OpenAI;
Lab::Gemini;
Lab::OpenAiCompatible; // configurable OpenAI-compatible endpoint
// ...
```
