## Get Started

> **Requires [PHP 8.2+](https://www.php.net/releases/)**

First, install OpenAI via the [Composer](https://getcomposer.org/) package manager:

```bash
composer require openai-php/client
```

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.
```bash
composer require guzzlehttp/guzzle
```

Then, interact with OpenAI's API:

```php
$yourApiKey = getenv('YOUR_API_KEY');
$client = OpenAI::client($yourApiKey);

$response = $client->responses()->create([
    'model' => 'gpt-4o',
    'input' => 'Hello!',
]);

echo $response->outputText; // Hello! How can I assist you today?
```

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

```php
$yourApiKey = getenv('YOUR_API_KEY');

$client = OpenAI::factory()
    ->withApiKey($yourApiKey)
    ->withOrganization('your-organization') // default: null
    ->withProject('Your Project') // default: null
    ->withBaseUri('openai.example.com/v1') // default: api.openai.com/v1
    ->withHttpClient($httpClient = new \GuzzleHttp\Client([])) // default: HTTP client found using PSR-18 HTTP Client Discovery
    ->withHttpHeader('X-My-Header', 'foo')
    ->withQueryParam('my-param', 'bar')
    ->withStreamHandler(fn (RequestInterface $request): ResponseInterface => $httpClient->send($request, [
        'stream' => true // Allows to provide a custom stream handler for the http client.
    ]))
    ->make();
```

## Usage

### `Models` Resource

#### `list`

Lists the currently available models, and provides basic information about each one such as the owner and availability.

```php
$response = $client->models()->list();

$response->object; // 'list'

foreach ($response->data as $result) {
    $result->id; // 'gpt-3.5-turbo-instruct'
    $result->object; // 'model'
    // ...
}

$response->toArray(); // ['object' => 'list', 'data' => [...]]
```

#### `retrieve`

Retrieves a model instance, providing basic information about the model such as the owner and permissioning.

```php
$response = $client->models()->retrieve('gpt-3.5-turbo-instruct');

$response->id; // 'gpt-3.5-turbo-instruct'
$response->object; // 'model'
$response->created; // 1642018370
$response->ownedBy; // 'openai'

$response->toArray(); // ['id' => 'gpt-3.5-turbo-instruct', ...]
```

#### `delete`

Delete a fine-tuned model.

```php
$response = $client->models()->delete('curie:ft-acmeco-2021-03-03-21-44-20');

$response->id; // 'curie:ft-acmeco-2021-03-03-21-44-20'
$response->object; // 'model'
$response->deleted; // true

$response->toArray(); // ['id' => 'curie:ft-acmeco-2021-03-03-21-44-20', ...]
```

### `Responses` Resource

#### `create`

Creates a model response. Provide text or image inputs to generate text or JSON outputs. Have the model call your own custom code or use built-in tools like web search or file search to use your own data as input for the model's response.

```php
$response = $client->responses()->create([
    'model' => 'gpt-4o-mini',
    'tools' => [
        [
            'type' => 'web_search_preview'
        ]
    ],
    'input' => "what was a positive news story from today?",
    'temperature' => 0.7,
    'max_output_tokens' => 150,
    'tool_choice' => 'auto',
    'parallel_tool_calls' => true,
    'store' => true,
    'metadata' => [
        'user_id' => '123',
        'session_id' => 'abc456'
    ]
]);

$response->id; // 'resp_67ccd2bed1ec8190b14f964abc054267'
$response->object; // 'response'
$response->createdAt; // 1741476542
$response->status; // 'completed'
$response->model; // 'gpt-4o-mini'
$response->outputText; // 'The combined response text of any `output_text` content.'

foreach ($response->output as $output) {
    $output->type; // 'message'
    $output->id; // 'msg_67ccd2bf17f0819081ff3bb2cf6508e6'
    $output->status; // 'completed'
    $output->role; // 'assistant'
    
    foreach ($output->content as $content) {
        $content->type; // 'output_text'
        $content->text; // The response text
        $content->annotations; // Any annotations in the response
    }
}

$response->usage->inputTokens; // 36
$response->usage->outputTokens; // 87
$response->usage->totalTokens; // 123

$response->toArray(); // ['id' => 'resp_67ccd2bed1ec8190b14f964abc054267', ...]
```

Create a model response with a function tool.

```php
$response = $client->responses()->create([
    'model' => 'gpt-4o-mini',
    'tools' => [
        [
            'type' => 'function',
            'name' => 'get_temperature',
            'description' => 'Get the current temperature in a given location',
            'parameters' => [
                'type' => 'object',
                'properties' => [
                    'location' => [
                        'type' => 'string',
                        'description' => 'The city and state, e.g. San Francisco, CA',
                    ],
                    'unit' => [
                        'type' => 'string',
                        'enum' => ['celsius', 'fahrenheit'],
                    ],
                ],
                'required' => ['location'],
            ],
        ]
    ],
    'input' => "What is the temperature in Rio Grande do Norte, Brazil?",
]);

foreach ($response->output as $item) {
    if ($item->type === 'function_call') {
        $name = $item->name ?? null;
        $args = json_decode($item->arguments ?? '{}', true) ?: [];

        if ($name === 'get_temperature') {
            // ✅ Call your custom function here with the extracted arguments
            // Example:
            // $temperature = get_temperature($args['location'], $args['unit'] ?? 'celsius');
            // Then, send the result back to the model if needed.
        }
    }
}
```

Create a response with hosted shell and an uploaded skill. See [Shell](https://developers.openai.com/api/docs/guides/tools-shell) and [Skills](https://developers.openai.com/api/docs/guides/tools-skills) for the execution environments and attachment formats.

```php
$response = $client->responses()->create([
    'model' => 'gpt-5.4',
    'tools' => [
        [
            'type' => 'shell',
            'environment' => [
                'type' => 'container_auto',
                'skills' => [
                    ['type' => 'skill_reference', 'skill_id' => 'skill_abc123'],
                ],
            ],
        ],
    ],
    'input' => 'Use the uploaded skill to count these words: one two three.',
]);

foreach ($response->output as $item) {
    if ($item->type === 'shell_call') {
        $item->action->commands; // Shell commands requested by the model
        $item->action->timeoutMs; // Optional execution timeout
        $item->environment; // Local environment or container reference
    }

    if ($item->type === 'shell_call_output') {
        foreach ($item->output as $output) {
            $output->stdout;
            $output->stderr;
            $output->outcome->type; // 'exit' or 'timeout'

            if ($output->outcome->type === 'exit') {
                $output->outcome->exitCode;
            }
        }
    }
}

$response->toArray();
```

Hosted shell runs on OpenAI. An automatically provisioned container can appear as `container_reference` in the response. Attachments may also use `inline` with a base64 ZIP source. With `environment.type = local`, your application executes the commands and supplies `shell_call_output` items; the client only parses and serializes these data structures.

#### `create streamed`

When you create a Response with stream set to true, the server will emit server-sent events to the client as the Response is generated. All events and their payloads can be found in [OpenAI docs](https://platform.openai.com/docs/api-reference/responses-streaming).

```php
$stream = $client->responses()->createStreamed([
    'model' => 'gpt-4o-mini',
    'tools' => [
        [
            'type' => 'web_search_preview'
        ]
    ],
    'input' => "what was a positive news story from today?",
]);

foreach ($stream as $response) {
    $response->event; // 'response.created'
}
```

#### `retrieve`

Retrieves a model response with the given ID.

```php
$response = $client->responses()->retrieve('resp_67ccd2bed1ec8190b14f964abc054267');

```

#### `retrieve streamed`

When you retrieve a Response with stream set to true, the server will emit server-sent events to the client as the Response is generated. All events and their payloads can be found in [OpenAI docs](https://platform.openai.com/docs/api-reference/responses-streaming).

```php
$stream = $client->responses()->retrieveStreamed('resp_67ccd2bed1ec8190b14f964abc054267', [

// 2. iteration => ['index' => 0, 'delta' => ['content' => 'Hello'], 'finish_reason' => null]
// 3. iteration => ['index' => 0, 'delta' => ['content' => '!'], 'finish_reason' => null]
// ...
```

To get usage report when using stream you can use `include_usage` in `stream_options` .

```php
$stream = $client->chat()->createStreamed([
    'model' => 'gpt-4',
    'messages' => [
        ['role' => 'user', 'content' => 'Hello!'],
    ],
    'stream_options'=>[
        'include_usage' => true,
    ]
]);

foreach($stream as $response){
    if($response->usage !== null){
        $response->usage->promptTokens; // 9,
        $response->usage->completionTokens; // 12,
        $response->usage->totalTokens; // 21

#### `submitToolOutputs`

When a run has the status: `requires_action` and `required_action.type` is `submit_tool_outputs`, this endpoint can be used to submit the outputs from the tool calls once they're all completed. All outputs must be submitted in a single request.

```php
$response = $client->threads()->runs()->submitToolOutputs(
    threadId: 'thread_tKFLqzRN9n7MnyKKvc1Q7868',
    runId: 'run_4RCYyYzX9m41WQicoJtUQAb8',
    parameters: [

            [
                'tool_call_id' => 'call_KSg14X7kZF2WDzlPhpQ168Mj',
                'output' => '12',
            ],
        ],
    ]
);

$response->id; // 'run_4RCYyYzX9m41WQicoJtUQAb8'
$response->object; // 'thread.run'
$response->createdAt; // 1623936000
$response->assistantId; // 'asst_gxzBkD1wkKEloYqZ410pT5pd'

</details>

## Meta Information

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

```php
$response = $client->completions()->create([
    'model' => 'gpt-3.5-turbo-instruct',
    'prompt' => 'Say this is a test',
]);

$meta = $response->meta();

$meta->requestId; // '574a03e2faaf4e9fd703958e4ddc66f5'

$meta->openai->model; // 'gpt-3.5-turbo-instruct'
$meta->openai->organization; // 'org-jwe45798ASN82s'
$meta->openai->version; // '2020-10-01'
$meta->openai->processingMs; // 425

$meta->requestLimit->limit; // 3000
$meta->requestLimit->remaining; // 2999
$meta->requestLimit->reset; // '20ms'

$meta->tokenLimit->limit; // 250000
$meta->tokenLimit->remaining; // 249984
$meta->tokenLimit->reset; // '3ms'
```

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

```php
$meta->toArray();

// [ 
//   'x-request-id' => '574a03e2faaf4e9fd703958e4ddc66f5',
//   'openai-model' => 'gpt-3.5-turbo-instruct',
//   'openai-organization' => 'org-jwe45798ASN82s',
//   'openai-processing-ms' => 402,
//   'openai-version' => '2020-10-01',
//   'x-ratelimit-limit-requests' => 3000,
//   'x-ratelimit-remaining-requests' => 2999,
//   'x-ratelimit-reset-requests' => '20ms',
//   'x-ratelimit-limit-tokens' => 250000,
//   'x-ratelimit-remaining-tokens' => 249983,
//   'x-ratelimit-reset-tokens' => '3ms',
// ]
```

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

```php
$stream = $client->completions()->createStreamed([
    'model' => 'gpt-3.5-turbo-instruct',
    'prompt' => 'Say this is a test',
]);
    
$stream->meta(); 
```

For further details about the rates limits and what to do if you hit them visit the [OpenAI documentation](https://platform.openai.com/docs/guides/rate-limits/rate-limits).

## 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.
```php
OpenAI::factory()
    ->withApiKey($apiKey)
    ->withOrganization($organization)
    ->withHttpClient(new \GuzzleHttp\Client(['timeout' => $timeout]))
    ->make();
```

## 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.

```php
use OpenAI\Testing\ClientFake;
use OpenAI\Responses\Completions\CreateResponse;

$client = new ClientFake([
    CreateResponse::fake([
        'choices' => [
            [
                'text' => 'awesome!',
            ],
        ],
    ]),
]);

$completion = $client->completions()->create([
    'model' => 'gpt-3.5-turbo-instruct',
    'prompt' => 'PHP is ',
]);

expect($completion['choices'][0]['text'])->toBe('awesome!');
```

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

```php
use OpenAI\Testing\ClientFake;
use OpenAI\Responses\Chat\CreateStreamedResponse;

$client = new ClientFake([
    CreateStreamedResponse::fake(fopen('file.txt', 'r'))
]);

$completion = $client->chat()->createStreamed([
    'model' => 'gpt-3.5-turbo',
    'messages' => [
        ['role' => 'user', 'content' => 'Hello!'],
    ],
]);

expect($response->getIterator()->current())
    ->id->toBe('chatcmpl-6yo21W6LVo8Tw2yBf7aGf2g17IeIl');
```

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

```php
// assert completion create request was sent
$client->assertSent(Completions::class, function (string $method, array $parameters): bool {
    return $method === 'create' &&
        $parameters['model'] === 'gpt-3.5-turbo-instruct' &&
        $parameters['prompt'] === 'PHP is ';
});
// or
$client->completions()->assertSent(function (string $method, array $parameters): bool {
    // ...
});

// assert 2 completion create requests were sent
$client->assertSent(Completions::class, 2);

// assert no completion create requests were sent
$client->assertNotSent(Completions::class);
// or
$client->completions()->assertNotSent();

// assert no requests were sent
$client->assertNothingSent();
```

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

```php
$client = new ClientFake([
    new \OpenAI\Exceptions\ErrorException([
        'message' => 'The model `gpt-1` does not exist',
        'type' => 'invalid_request_error',
        'code' => null,
    ], 404)
]);

// the `ErrorException` will be thrown
$completion = $client->completions()->create([
    'model' => 'gpt-3.5-turbo-instruct',
    'prompt' => 'PHP is ',
]);
```

## Webhooks

The package includes a signature verifier for OpenAI webhooks. To verify the signature of incoming webhook requests, you can use the `OpenAI\Webhooks\SignatureVerifier` class.

```php
use OpenAI\Webhooks\SignatureVerifier;
use OpenAI\Exceptions\WebhookVerificationException;

$verifier = new SignatureVerifier('whsec_{your-webhook-signing-secret}');

try {
    $verifier->verify($incomingRequest);
    
    // The request is verified
} catch (WebhookVerificationException $exception) {
    // The request could not be verified
}
```

## Services

### Azure

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

```php
$client = OpenAI::factory()
    ->withBaseUri('{your-resource-name}.openai.azure.com/openai/deployments/{deployment-id}')
    ->withHttpHeader('api-key', '{your-api-key}')
    ->withQueryParam('api-version', '{version}')
    ->make();
```

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:

```php
$result = $client->completions()->create([
    'prompt' => 'PHP is'
]);
```
