OpenAIChat

💬 Usage of OpenAIChat

To streamline your setup, our PHP repository recognizes OpenAI API keys stored in two default locations: getenv('OPENAI_API_KEY') or $_ENV['OPENAI_API_KEY']. Simply add your OpenAI key to your ENV file, and no additional configuration is necessary. We also use $_ENV because frameworks like Symfony typically disable getenv by default.

If you want to use the default model, this is enough, so not a lof ot code:

use EasyAI\Chat\OpenAIChat; // Using OpenAI Chat

// here is the code to call OpenAI API
$chat = new OpenAIChat();
$response = $chat->generateText('What is the population of Tokyo area, answer with only a number.');
// $response = "37 million"

If you want to select a specific modal, you need to use the Config & Enums:

use EasyAI\OpenAIConfig; // Using OpenAI Config
use EasyAI\Chat\OpenAIChat; // Using OpenAI Chat
use EasyAI\Chat\Enums\OpenAIChatModel; // Using Enmus OpenAIChatModel

// e.g. in dependencyInjection
$config = new OpenAIConfig();
$config->apiKey = $_ENV['OTHER_KEY']; // Here you can define your key (as default we are using getenv('OPENAI_API_KEY') or $_ENV['OPENAI_API_KEY'])
$config->model = OpenAIChatModel::Gpt35Turbo->getModelName(); // Here you can define the model
$chat = new OpenAIChat($config);

// here is the code to call OpenAI API
$response = $chat->generateText('What is the population of Tokyo area, answer with only a number.');
// $response = "37 million"

Right now you can choose these enums:

/* Currently points to gpt-3.5-turbo-0125. */
OpenAIChatModel::Gpt35Turbo => 'gpt-3.5-turbo',

/* Currently points to gpt-4-0613. See continuous model upgrades. */
OpenAIChatModel::Gpt4 => 'gpt-4',

/* GPT-4 Turbo preview model. Currently points to gpt-4-0125-preview. */
OpenAIChatModel::Gpt4TurboPreview => 'gpt-4-turbo-preview',

/* Currently points to gpt-4-turbo-2024-04-09. */
OpenAiChatModel::Gpt4Turbo => 'gpt-4-turbo',
