Lingoda AI SDK

Framework-agnostic PHP SDK for AI providers with typed results and platform abstraction.

🚀 Quick Start

use Lingoda\AiSdk\Platform;
use Lingoda\AiSdk\Client\OpenAI\OpenAIClientFactory;

// Create client using factory
$client = OpenAIClientFactory::createClient('your-api-key');
$platform = new Platform([$client]);

// Simple ask() method - automatically uses default model
$result = $platform->ask('Hello, AI!');
echo $result->getContent(); // TextResult

// Or specify a specific model
$result = $platform->ask('Hello, AI!', 'gpt-4o-mini');
echo $result->getContent();

// Audio capabilities
$audioResult = $platform->textToSpeech('Hello world', $audioOptions);
$transcription = $platform->transcribeAudio('/path/to/audio.mp3', $options);

✨ Key Features

• 🔌 Framework Agnostic - No dependencies on Symfony or other frameworks
• 🛡️ Security First - Built-in data sanitization and attribute-based protection
• 🎯 Type Safe - Strongly-typed results and prompt value objects
• 🌐 Multi-Provider - OpenAI, Anthropic, Gemini support with flexible configuration
• 🎭 Capabilities - Models declare supported features (vision, tools, audio, streaming, reasoning)
• ⚡ Performance - Built-in rate limiting and token estimation with exponential backoff
• 📝 Rich Prompts - Parameterized prompts and conversation management
• 🎵 Audio Support - Text-to-speech, transcription, and translation with multiple formats
• 🔄 Streaming - Real-time response streaming support

🏗️ Architecture

Platform → Providers → Models → Clients → AI APIs
    ↓
Results ← Security ← Capabilities ← Response

• Platform: Main entry point for AI operations
• Providers: Manage models for each AI service (OpenAI, Anthropic, Gemini)
• Models: Individual AI models with declared capabilities
• Clients: Handle API communication with rate limiting
• Results: Type-safe responses (TextResult, BinaryResult, StreamResult, ObjectResult, ToolCallResult)

🎨 Usage Patterns

Simple Text Generation

$result = $platform->ask('Explain AI');
echo $result->getContent(); // string
print_r($result->getMetadata()); // usage, model info, etc.

Parameterized Prompts

$template = UserPrompt::create('Hello {{name}}, tell me about {{topic}}');
$prompt = $template->withParameters([
    'name' => 'Alice',
    'topic' => 'machine learning'
]);

// Use ask() method with prompt objects
$result = $platform->ask($prompt);

Conversations with Context

$conversation = Conversation::withSystem(
    UserPrompt::create('What is quantum computing?'),
    SystemPrompt::create('You are a helpful physics expert')
);

// ask() method supports Conversation objects
$result = $platform->ask($conversation, 'claude-sonnet-4');

Automatic Data Protection

// Sensitive data is automatically sanitized
$prompt = UserPrompt::create('My email is john@example.com');
// Sent to AI as: "My email is [REDACTED_EMAIL]"
$result = $platform->ask($prompt);

// Disable sanitization if needed
$platform = new Platform([$client], enableSanitization: false);

🔧 Requirements

• PHP ^8.3
• PSR-18 HTTP Client (Symfony HTTP Client included)
• PSR-7 HTTP Messages (nyholm/psr7 included)
• PSR-3 Logger (optional)

🎵 Audio Features

use Lingoda\AiSdk\Audio\OpenAI\AudioOptions;

// Text-to-Speech
$options = AudioOptions::textToSpeech(
    model: AudioSpeechModel::TTS_1,
    voice: AudioSpeechVoice::NOVA,
    format: AudioSpeechFormat::MP3
);
$audioResult = $platform->textToSpeech('Hello world', $options);
file_put_contents('speech.mp3', $audioResult->getContent());

// Speech-to-Text
$transcription = $platform->transcribeAudio('audio.mp3', $transcriptionOptions);
echo $transcription->getContent(); // "Hello world"

// Translation to English
$translation = $platform->translateAudio('spanish-audio.mp3', $translationOptions);
