Using $_ENV[""] in the OpenAIChat Class for e.g. Smyfony Error: You have to provide a OPENAI_API_KEY env var to request OpenAI .

[RHosono]

For example, if you use a framework such as Symfony, you cannot use this part of the code, as Symfony blocks the getenv because it is not thread safe.

- "use_putenv" to tell Dotenv to set env vars using putenv() (NOT RECOMMENDED.)
src/Symfony/Component/Runtime/SymfonyRuntime.php

->usePutenv($options['use_putenv'] ?? false)
src/Symfony/Component/Runtime/SymfonyRuntime.php

Should we therefore add another check to use the global $_ENV[""] for example to prevent duplicate configuration? Any opinions on this?

public function __construct(?OpenAIConfig $config = null)
{
	if ($config instanceof OpenAIConfig && $config->client instanceof Client) {
		$this->client = $config->client;
	} else {
		$apiKey = $config->apiKey ?? getenv('OPENAI_API_KEY');
		if (! $apiKey) {
			throw new Exception('You have to provide a OPENAI_API_KEY env var to request OpenAI .');
		}

		$this->client = OpenAI::client($apiKey);
	}
	$this->model = $config->model ?? OpenAIChatModel::Gpt4Turbo->getModelName();
	$this->modelOptions = $config->modelOptions ?? [];
}
