Beyond Text: Laravel AI SDK's Multimodal Capabilities

Most AI SDKs focus on text generation. Laravel AI SDK handles text, images, audio, transcripts, embeddings, and file management—all from a single, elegant API.

Modern applications need AI that understands more than words. They need systems that can generate images, transcribe audio, create embeddings, rerank results, and manage vector stores. Laravel AI SDK provides complete multimodal capabilities without requiring multiple integrations or learning different APIs.

The SDK transforms raw content into unique experiences. Whether you're building content generation tools, intelligent search systems, or comprehensive AI applications, multimodal capabilities unlock possibilities that text-only systems can't match.

Image Generation: From Prompts to Visuals

Laravel AI SDK makes image generation as simple as text generation. Create visuals with a single method call:

use Laravel\Ai\Image;
use Laravel\Ai\Files;

$image = Image::of('A donut sitting on the kitchen counter.')
    ->quality('high')
    ->landscape()
    ->timeout(120)
    ->generate();

The SDK supports:

• Quality control — High-resolution outputs for professional use
• Aspect ratios — Landscape, portrait, or square formats
• Custom timeouts — Handle long-running generations gracefully

Image Remixing

Beyond generation, the SDK enables image remixing—transforming existing images with AI:

$image = Image::of('Update this photo to be in the style of an impressionist painting.')
    ->attachments([
        Files\Image::fromStorage('photo.jpg'),
    ])
    ->landscape()
    ->generate();

This capability enables:

• Style transfer — Apply artistic styles to photos
• Image enhancement — Improve quality and composition
• Creative transformations — Generate variations and alternatives

Image generation becomes a native Laravel feature, integrated seamlessly with your application workflow.

Audio Generation: Text to Speech with Control

Convert text to natural-sounding speech with fine-grained control:

use Laravel\Ai\Audio;

$audio = Audio::of('I love coding with Laravel.')->generate();

Custom Voices

The SDK supports custom voice selection:

$audio = Audio::of('I love coding with Laravel.')
    ->voice('voice-id-or-name')
    ->generate();

Voice Instructions

Add personality and style to generated audio:

$audio = Audio::of('I love coding with Laravel.')
    ->female()
    ->instructions('Said like a pirate.')
    ->generate();

Audio generation enables:

• Accessibility — Convert text content to audio
• Multimedia content — Create podcasts, narrations, and voiceovers
• Personalization — Match voice characteristics to brand or context

Audio becomes programmatically generated, enabling dynamic content creation at scale.

Transcription: Audio to Text Intelligence

Convert audio files to text with advanced features:

use Laravel\Ai\Transcription;
use Laravel\Ai\Responses\TranscriptionResponse;

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

Diarization

Identify who said what in multi-speaker recordings:

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

Diarization enables:

• Meeting transcripts — Identify speakers in conference calls
• Interview analysis — Separate questions from answers
• Content organization — Structure audio content by speaker

Queued Transcription

Handle long audio files asynchronously:

Transcription::fromStorage('audio.mp3')
    ->queue()
    ->then(function (TranscriptionResponse $transcript) {
        // Process completed transcription
    });

Queuing ensures non-blocking operations for large files while maintaining responsive user experiences.

Embeddings: Semantic Understanding

Create vector representations that capture semantic meaning:

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

$embeddings = Str::of('Napa Valley has great wine.')->toEmbeddings();

Embeddings enable:

• Semantic search — Find content by meaning, not keywords
• Similarity matching — Identify related content automatically
• Clustering — Group similar items together
• Recommendation systems — Suggest relevant content based on meaning

The SDK integrates embeddings natively into Laravel's string helpers, making semantic operations as natural as string manipulation.

Reranking: Intelligent Result Ordering

Improve search relevance by reranking results based on query intent:

use Laravel\Ai\Reranking;

$response = Reranking::of([
    'Django is a Python web framework.',
    'Laravel is a PHP web application framework.',
    'React is a JavaScript library for building user interfaces.',
])->rerank('PHP frameworks');

$response->first()->document; // "Laravel is a PHP web application framework."

Reranking ensures:

• Relevance — Most relevant results appear first
• Context awareness — Results match user intent, not just keywords
• Better UX — Users find what they need faster

Search becomes intelligent, understanding meaning beyond literal text matching.

File Management: Vector Stores and RAG

Transform documents into searchable knowledge bases:

use Laravel\Ai\Files\Document;
use Laravel\Ai\Files\Image;
use Laravel\Ai\Contracts\Agent;
use Laravel\Ai\Providers\Tools\FileSearch;

// Store a file for vectorization
$response = Document::fromStorage('transcript.pdf', disk: 'local')->put();

// Build a file search agent
class SalesCoach implements Agent
{
    use Promptable;

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

File management enables:

• RAG systems — Retrieval-Augmented Generation for context-aware AI
• Document search — Find information across large document collections
• Knowledge bases — Build intelligent assistants that understand your content

Files become searchable, intelligent resources that agents can query and understand.

Multimodal Agents: Complete Understanding

Agents can process multiple content types simultaneously:

use App\Ai\Agents\ImageAnalyzer;
use Laravel\Ai\Files;

$response = (new ImageAnalyzer)->prompt(
    'What is in this image?',
    attachments: [
        Files\Image::fromStorage('photo.jpg'),
        Files\Document::fromPath('/home/laravel/context.md'),
    ]
);

Multimodal agents can:

• Analyze images — Understand visual content
• Process documents — Extract information from files
• Combine modalities — Use multiple content types for comprehensive understanding

Agents become comprehensive systems that understand content in all its forms.
