PHP 8.0+ OpenAI API 客户端，包含完全类型化/文档化的请求+响应模型，通过 HTTPPug 支持 guzzlehttp/guzzle + symfony/http-client，以及异步/并行请求。

该客户端使用 openai 的 OpenAPI 和 jane-php 生成。

功能

• 请求模型是类型化的，并包含 OpenAPI 文档中的描述。
• 使用 HTTPPug 作为 HTTP 抽象层
  • 支持许多 HTTP 客户端，如 guzzlehttp/guzzle 或 symfony/http-client
  • 许多有用的插件，如缓存或重试
  • Symfony 扩展包
• 异步/并行请求。

这是一个社区维护的非官方库。

安装

composer require sourceability/openai-client

入门指南

require __DIR__ . '/vendor/autoload.php';

use Sourceability\OpenAIClient\Client;
use Sourceability\OpenAIClient\Generated\Model\CreateCompletionRequest;

$apiClient = Client::create(
    apiKey: getenv('OPENAI_API_KEY')
);

$requests = [
    (new CreateCompletionRequest())
        ->setModel('text-davinci-003')
        ->setTemperature(0)
        ->setMaxTokens(512)
        ->setPrompt('The jane php library is very useful because'),
    new CreateCompletionRequest(
        model: 'text-davinci-003',
        temperature: 0,
        maxTokens: 512,
        prompt: 'Symfony symfony symfony is like sourceability on a'
    ),
];
$completionResponses = $apiClient->createCompletions($requests);

var_dump($completionResponses);

使用 /v1/chat/completions 与 ChatGPT 交互

<?php

require __DIR__ . '/vendor/autoload.php';

use Sourceability\OpenAIClient\Client;
use Sourceability\OpenAIClient\Generated\Model\ChatCompletionRequestMessage;
use Sourceability\OpenAIClient\Generated\Model\CreateChatCompletionRequest;

$apiClient = Client::create(
    apiKey: getenv('OPENAI_API_KEY')
);

$requests = [
    new CreateChatCompletionRequest(
        model: 'gpt-3.5-turbo',
        temperature: 0,
        messages: [
            new ChatCompletionRequestMessage(
                role: 'user',
                content: 'The jane php library is very useful because'
            )
        ],
    ),
    new CreateChatCompletionRequest(
        model: 'gpt-3.5-turbo',
        temperature: 0,
        messages: [
            new ChatCompletionRequestMessage(
                role: 'user',
                content: 'Symfony symfony symfony is like sourceability on a'
            )
        ],
    ),
];
$completionResponses = $apiClient->createChatCompletions($requests);

var_dump($completionResponses);

成本计算器

您可以使用依赖于 brick/money 的 ResponseCostCalculator 来计算响应的成本

use Sourceability\OpenAIClient\Pricing\ResponseCostCalculator;

$responseCostCalculator = new ResponseCostCalculator();
$responseCost = $responseCostCalculator->calculate($myCompletionResponse);

var_dump([
    'total' => $responseCost->getTotal()->formatTo('en_US'),
    'prompt' => $responseCost->getPrompt()->formatTo('en_US'),
    'completion' => $responseCost->getCompletion()->formatTo('en_US'),
]);

array(3) {
  ["total"]=>
  string(10) "$0.0001280"
  ["prompt"]=>
  string(10) "$0.0000980"
  ["completion"]=>
  string(10) "$0.0000300"
}
