Installation

Install the library using Composer:

composer require sonichaos360/lugpt

Usage

Initialization

Initialize the LuGPT class with your OpenAI API key:

require_once 'vendor/autoload.php';

use Sonichaos360\LuGPT\Completions;

$apiKey = 'your_openai_api_key';
$model = 'gpt-3.5-turbo';
$maxTokens = '1500';
$temp = '1';
$conversationsPath = '../conversations'; //Optional, necessary only if you will manage conversation history using createConversation()

$luGPT = new Completions($apiKey, $model, $maxTokens, $temp, $conversationsPath);

In this example, we are using the gpt-3.5-turbo model, which is optimized for chat. The chat-optimized models can be used with the chat() method. If you want to use the completion() method, you will need to use text-davinci-003 or another non-chat-optimized model. A list of all available OpenAI models can be found here.

Chat

Send a message using Chat Completions API:

$systemMessage = 'You are an assistant that translates English to French.';
$userMessage = 'Translate the following sentence: "Hello, how are you?"';
$response = $luGPT->Chat($systemMessage, $userMessage);

echo $response['choices'][0]['message']['content'];

Conversations

Create and manage conversations:

// Create a new conversation
$conversationId = $luGPT->createConversation();

// Send messages within the conversation
$systemMessage = 'You are an assistant that translates between any languages.';
$userMessage1 = 'Translate the following sentence from English to French: "Hello, how are you?"';
$response1 = $luGPT->Chat($systemMessage, $userMessage1, $conversationId);

echo $response1['choices'][0]['message']['content']." | ";

$userMessage2 = 'Now, please translate this: "I am fine, thank you."';
$response2 = $luGPT->Chat($systemMessage, $userMessage2, $conversationId);

echo $response2['choices'][0]['message']['content']." | ";

This example uses a conversationId, which allows the API to remember the context of previous messages and responses. The conversations will be created as separate JSON files stored in the $conversationsPath directory.

Completion

Send a prompt to the text-davinci-003 or other non chat completions optimized model:

$prompt = 'Translate the following English sentence to French: "Hello, how are you?"';
$response = $luGPT->Completion($prompt);

echo $response["choices"][0]["text"];

TODO

Here are some upcoming features and improvements we have planned for the LuGPT library. We encourage contributors to take on these tasks or suggest new ones by creating issues on GitHub:

1. Refactor the saveTokens() function, which was deactivated due to strange behavior with non-English language characters.
2. Improve error handling and provide more informative error messages.
3. Implement unit tests for the library to ensure code quality and functionality.

Please consider contributing to the development of these features or suggesting new ones by creating an issue or submitting a pull request. Your input and collaboration are greatly appreciated.
