Get Started

Requires PHP 8.1+

First, install OpenAI via the Composer package manager:

Ensure that the php-http/discovery composer plugin is allowed to run or install a client manually if your project does not already have a PSR-18 client integrated.

Then, interact with OpenAI's API:

If necessary, it is possible to configure and create a separate client.

create

Meta Information

On all response objects you can access the meta information returned by the API via the meta() method.

The toArray() method returns the meta information in the form originally returned by the API.

On streaming responses you can access the meta information on the reponse stream object.

For further details about the rates limits and what to do if you hit them visit the OpenAI documentation.

Troubleshooting

Timeout

You may run into a timeout when sending requests to the API. The default timeout depends on the HTTP client used.

You can increase the timeout by configuring the HTTP client and passing in to the factory.

This example illustrates how to increase the timeout using Guzzle.

Testing

The package provides a fake implementation of the OpenAI\Client class that allows you to fake the API responses.

To test your code ensure you swap the OpenAI\Client class with the OpenAI\Testing\ClientFake class in your test case.

The fake responses are returned in the order they are provided while creating the fake client.

All responses are having a fake() method that allows you to easily create a response object by only providing the parameters relevant for your test case.

In case of a streamed response you can optionally provide a resource holding the fake response data.

After the requests have been sent there are various methods to ensure that the expected requests were sent:

To write tests expecting the API request to fail you can provide a Throwable object as the response.

Services

Azure

In order to use the Azure OpenAI Service, it is necessary to construct the client manually using the factory.

To use Azure, you must deploy a model, identified by the {deployment-id}, which is already incorporated into the API calls. As a result, you do not have to provide the model during the calls since it is included in the BaseUri.

Therefore, a basic sample completion call would be:
