Installation

composer require lingoda/ai-bundle

Quick Start

1. Installation

composer require lingoda/ai-bundle

2. Configuration

Create config/packages/lingoda_ai.yaml and add your API keys to .env:

Step 1: Add API keys to .env

OPENAI_API_KEY=sk-your-openai-key
ANTHROPIC_API_KEY=sk-ant-your-anthropic-key
GEMINI_API_KEY=your-gemini-key

Step 2: Create configuration file

Create config/packages/lingoda_ai.yaml:

lingoda_ai:
    default_provider: openai # Used when ask() called without model parameter
    providers:
        openai:
            api_key: '%env(OPENAI_API_KEY)%'
            default_model: 'gpt-4o-2024-11-20' # Override default model
            # Optional: Custom HTTP client with retry logic, timeouts, etc.
            # http_client: 'openai.http_client'
            # timeout: 30 # Request timeout (only used if no custom http_client)
        anthropic:
            api_key: '%env(ANTHROPIC_API_KEY)%'
            default_model: 'claude-3-5-sonnet-20241022'
            # Optional: Custom HTTP client for Anthropic requests
            # http_client: 'anthropic.http_client'
            # timeout: 30
        gemini:
            api_key: '%env(GEMINI_API_KEY)%'
            default_model: 'gemini-2.0-pro'
            # Optional: Custom HTTP client for Gemini requests
            # http_client: 'gemini.http_client'
            # timeout: 30
    sanitization:
        enabled: true # Auto-sanitize sensitive data
        patterns: [] # Custom sanitization patterns
    logging:
        enabled: true
        service: 'monolog.logger' # Logger service ID

3. Usage

The bundle provides two usage patterns:

Usage Patterns

Pattern 1: Multi-Provider Platform (Flexible)

Use when you need access to multiple AI providers in the same service:

use Lingoda\AiSdk\Platform;
use Lingoda\AiSdk\PlatformInterface;

class MyService
{
    public function __construct(
        private Platform $platform,  // AI SDK Platform with ALL configured providers
        // OR use the interface:
        // private PlatformInterface $platform
    ) {}

    public function compareModels(string $prompt): array
    {
        return [
            'openai' => $this->platform->ask($prompt, 'gpt-4o-mini')->getContent(),
            'anthropic' => $this->platform->ask($prompt, 'claude-3-5-haiku-20241022')->getContent(),
            'gemini' => $this->platform->ask($prompt, 'gemini-2.5-flash-002')->getContent(),
        ];
    }

    public function useDefaultProvider(string $prompt): string
    {
        // Uses your configured default_provider
        return $this->platform->ask($prompt)->getContent();
    }
}

Pattern 2: Single-Provider Platforms (Simple)

Use when you want dedicated platforms for specific providers:

use Lingoda\AiBundle\Platform\ProviderPlatform;
use Lingoda\AiSdk\PlatformInterface;

class MyService
{
    public function __construct(
        // Named parameter autowiring - the bundle automatically wires the right provider:
        private ProviderPlatform $openaiPlatform,      // Only OpenAI models
        private ProviderPlatform $anthropicPlatform,   // Only Anthropic models
        private PlatformInterface $geminiPlatform,     // Interface alias also works
    ) {}

    public function generateWithOpenAI(string $prompt): string
    {
        // Only has access to OpenAI models
        return $this->openaiPlatform->ask($prompt)->getContent();
    }

    public function generateWithAnthropic(string $prompt): string
    {
        // Only has access to Anthropic models
        return $this->anthropicPlatform->ask($prompt)->getContent();
    }

    public function generateWithGemini(string $prompt): string
    {
        // Only has access to Gemini models
        return $this->geminiPlatform->ask($prompt)->getContent();
    }
}

Advanced AI SDK Features

All AI SDK features work seamlessly:

use Lingoda\AiSdk\Prompt\UserPrompt;
use Lingoda\AiSdk\Prompt\Conversation;
use Lingoda\AiSdk\Prompt\SystemPrompt;

class AdvancedService
{
    public function __construct(
        private Platform $platform
    ) {}

    public function parameterizedPrompts(): string
    {
        $template = UserPrompt::create('Hello {{name}}, explain {{topic}} in simple terms');
        $prompt = $template->withParameters([
            'name' => 'Alice',
            'topic' => 'machine learning'
        ]);

        return $this->platform->ask($prompt)->getContent();
    }

    public function conversations(): string
    {
        $conversation = Conversation::withSystem(
            SystemPrompt::create('You are a helpful coding assistant'),
            UserPrompt::create('How do I implement dependency injection?')
        );

        return $this->platform->ask($conversation)->getContent();
    }

    public function audioFeatures(): void
    {
        // Text-to-Speech (requires OpenAI)
        $audioResult = $this->platform->textToSpeech('Hello world');
        file_put_contents('speech.mp3', $audioResult->getContent());

        // Speech-to-Text (requires OpenAI)
        $transcription = $this->platform->transcribeAudio('audio.mp3');
        echo $transcription->getContent();
    }
}

Rate Limiting

The bundle provides enhanced rate limiting that integrates with Symfony's rate limiter component (enabled by default):

Enhanced Rate Limiting (Enabled by Default)

The Bundle enables enhanced rate limiting by default with sensible provider defaults:

lingoda_ai:
    providers:
        openai:
            api_key: '%env(OPENAI_API_KEY)%'
    # Enhanced rate limiting is enabled by default
    rate_limiting:
        enabled: true  # Default - can be disabled if needed

Custom Rate Limits (Optional)

Configure custom limits per provider when needed:

framework:
    cache:
        pools:
            rate_limiter_pool:
                adapter: cache.adapter.redis

lingoda_ai:
    providers:
        openai:
            api_key: '%env(OPENAI_API_KEY)%'

    rate_limiting:
        enabled: true  # Enable enhanced rate limiting
        storage: 'rate_limiter_pool'  # Use Redis for e.g. for shared state

        providers:
            openai:
                requests:
                    limit: 180    # Requests per minute
                    rate:
                        interval: '1 minute'
                        amount: 180
                tokens:
                    limit: 450000  # Tokens per minute
                    rate:
                        interval: '1 minute'
                        amount: 450000

Benefits of Enhanced Rate Limiting (Default):

• Shared State: Multiple app instances share rate limits via Redis
• Provider Defaults: Sensible rate limits for each provider out of the box
• Environment-Specific: Different limits for dev/staging/prod
• Monitoring: Integration with Symfony profiler for debugging
• Custom Limits: Override with provider-specific limits based on your API quotas

When to Keep Enabled (Default):

• ✅ Most production applications (recommended default)
• ✅ Multi-instance deployments (load balanced apps)
• ✅ Applications needing predictable rate limiting behavior

When to Disable:

• ❌ Local development with unlimited API quotas
• ❌ Testing environments where you want to bypass limits

See Rate Limiting Documentation for complete configuration options.

Advanced Configuration

Custom HTTP Clients

You can configure custom HTTP clients per provider for advanced retry logic, timeouts, and request customization:

# config/packages/framework.yaml
framework:
    http_client:
        scoped_clients:
            openai.http_client:
                base_uri: 'https://api.openai.com'
                timeout: 60
                retry_failed:
                    max_retries: 3
                    delay: 1000
                    multiplier: 2
                    http_codes:
                        0: ['GET', 'POST'] # Network errors
                        429: true # Rate limits
                        500: ['GET', 'POST'] # Server errors
                headers:
                    'User-Agent': 'MyApp/1.0'

            anthropic.http_client:
                base_uri: 'https://api.anthropic.com'
                timeout: 45
                retry_failed:
                    max_retries: 2
                    delay: 500

# config/packages/lingoda_ai.yaml
lingoda_ai:
    providers:
        openai:
            api_key: '%env(OPENAI_API_KEY)%'
            http_client: 'openai.http_client' # Use custom client
        anthropic:
            api_key: '%env(ANTHROPIC_API_KEY)%'
            http_client: 'anthropic.http_client' # Use custom client

This gives you full control over:

• Retry strategies for handling rate limits and network errors
• Custom timeouts per provider based on your needs
• Request/response headers for debugging and user-agent identification
• Base URIs if using proxy servers or custom endpoints
