Azure OpenAI Provider

[g3luka]

I needed to use OpenAI via Azure, which has a compatible API, but with some differences in the request besides the baseURL.

The differences are:

• The baseURL is not fixed, each account generates different URLs;
• The DeploymentId is concatenated in the base URL, which is also the name of the model;
• It is mandatory to send the api-version as a Query Parameter, which is informed in the Azure Dashboard.

Here is the code I made extending the existing OpenAI Provider.

I tested it and it worked beautifully!

<?php

namespace NeuronAI\Providers\OpenAI;

use GuzzleHttp\Client;
use NeuronAI\Providers\OpenAI\OpenAI;

class AzureOpenAI extends OpenAI
{
    protected string $baseUri = "https://%s/openai/deployments/%s";

    public function __construct(
        protected string $key,
        protected string $endpoint,
        protected string $model,
        protected string $version,
        protected array $parameters = [],
    ) {
        $this->setBaseUrl();
        $this->client = new Client([
            'base_uri' => $this->baseUri,
            'query'    => [
                'api-version' => $this->version,
            ],
            'headers' => [
                'Authorization' => 'Bearer '.$this->key,
                'Accept' => 'application/json',
                'Content-Type' => 'application/json',
            ],
        ]);
    }

    private function setBaseUrl()
    {
        $this->endpoint = preg_replace('/^https?:\/\/([^\/]*)\/?$/', '$1', $this->endpoint);
        $this->baseUri = sprintf($this->baseUri, $this->endpoint, $this->model);
        $this->baseUri = trim($this->baseUri, '/').'/';
    }
}

I'm also going to make a Provider for AWS Bedrock.
