README

A powerful Symfony bundle that provides unified access to multiple AI providers (ChatGPT, Gemini, DeepSeek) with a simple, consistent interface.

✨ Features

• Multi-provider support: Switch between ChatGPT, Gemini, DeepSeek and more
• Simple configuration: YAML-based setup with environment variables
• Extensible architecture: Easily add new AI providers
• Smart defaults: Pre-configured with recommended models for each provider
• Production-ready: Built on Symfony's HttpClient for reliability
• Caching support: Optional caching of API responses

📦 Installation

Requirements

• PHP 8.1 or higher
• Symfony 5.4+ or 6.0+

1. Install with Composer

composer require sbh/ai-integration-bundle

⚙️ Configuration

config/packages/ai_integration.yaml

ai_integration:
    default_provider: chatgpt
    providers:
        chatgpt:
            api_key: '%env(CHATGPT_API_KEY)%'
            model: 'gpt-4o'
        gemini:
            api_key: '%env(GEMINI_API_KEY)%'
            model: 'gemini-1.5-pro'
        deepseek:
            api_key: '%env(DEEPSEEK_API_KEY)%'
            model: 'deepseek-chat'

Add to your API keys in .env

CHATGPT_API_KEY=sk-xxxx
GEMINI_API_KEY=xxxx
DEEPSEEK_API_KEY=xxxx

🛠 Usage

Inject the AIClientFactory into your service or controller.

use Sbh\AiIntegrationBundle\Service\AIClientFactory;

public function __construct(private AIClientFactory $factory) {}

public function askAI(): void
{
    $client = $this->factory->getClient('gemini'); // or chatgpt, deepseek...
    $answer = $client->chat('What is Symfony?');
    dump($answer);
}

Or via a route:

#[Route('/ask/{provider}', name: 'ask_ai')]
public function ask(AIClientFactory $factory, string $provider = 'chatgpt'): JsonResponse
{
    $client = $factory->getClient($provider);
    $answer = $client->chat('Explain Symfony Bundles');
    return $this->json(['provider' => $provider, 'answer' => $answer]);
}

➕ Adding a New AI Provider

• Create a new Client class in src/Service implementing AIClientInterface.

namespace Sbh\AiIntegrationBundle\Service;

use Symfony\Contracts\HttpClient\HttpClientInterface;

class ClaudeClient implements AIClientInterface
{
    public function __construct(
        private string $apiKey,
        private ?string $model,
        private HttpClientInterface $httpClient
    ) {}

    public function chat(string $prompt, array $options = []): string
    {
        // Call the Claude API here
    }
}

• Add its configuration in ai_integration.yaml:

providers:
    claude:
        api_key: '%env(CLAUDE_API_KEY)%'
        model: 'claude-3-opus'

 Update the AIClientFactory to add a case 'claude' in the match() statement.

📜 Requirements

• PHP >=8.1

• Symfony ^6.0 || ^7.0

• symfony/http-client

🗺 Roadmap

• ✅ Add support for service tags & auto-discovery (no factory changes for new tools).

• ✅ Streaming support for long responses.

• ✅ Embeddings & vector search integration (pgvector, Pinecone).
