Warum reagiert die OpenAI Chat GPT (GPT-3.5) API nicht, wenn der Stream-Parameter auf „false“ gesetzt ist?

Sie können $prompt 值。当我输入此提示值时,chat GPT 不会给出结果。但这是因为参数中的 "stream" => false 。如果 "stream" => true in meiner App unten sehen, wie das Chatten mit GPT zu Ergebnissen führt.

Meine Frage ist, warum Chat-GPT keine Ergebnisse liefert, wenn "stream" => false . Und was zu tun ist, um Ergebnisse zu erzielen.

$API_KEY = "API_KEY_HERE";

$model = 'gpt-3.5-turbo';
$header = [
    "Authorization: Bearer " . $API_KEY,
    "Content-type: application/json",
];

$temperature = 0.6;
$frequency_penalty = 0;
$presence_penalty= 0;
$prompt = 'What can you help me with? For example: What do you suggest to keep me motivated?';
 

$messages = array(
    array(
        "role" => "system",
        "content" => "Your name is 'JOHN DOE'. I want you to act as a motivational coach. I will provide you with some information about someone's goals and challenges, and it will be your job to come up with strategies that can help this person achieve their goals. This could involve providing positive affirmations, giving helpful advice or suggesting activities they can do to reach their end goal. if you don't understand the question, don't think too much, tell the user to be more specific with more details"
        ),
    array(
        "role" => "assistant",
        "content" => "Hello, I'm JOHN DOE, and I'm a motivational coach who loves helping people find their drive and achieve their goals. With years of experience in coaching and personal development, I've developed a unique approach to motivation that combines mindset, energy, and action."
    ),
    array(
        "role" => "user",
        "content" => $prompt
    )
);
//Turbo model
$isTurbo = true;
$url = "https://api.openai.com/v1/chat/completions";
$params = json_encode([
    "messages" => $messages,
    "model" => $model,
    "temperature" => $temperature,
    "max_tokens" => 1024,
    "frequency_penalty" => $frequency_penalty,
    "presence_penalty" => $presence_penalty,
    "stream" => false
]);

$curl = curl_init($url);
$options = [
    CURLOPT_POST => true,
    CURLOPT_HTTPHEADER => $header,
    CURLOPT_POSTFIELDS => $params,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_SSL_VERIFYPEER => false,
    CURLOPT_SSL_VERIFYHOST => 0,
    CURLOPT_WRITEFUNCTION => function($curl, $data) {
        //echo $curl;
        $httpCode = curl_getinfo($curl, CURLINFO_HTTP_CODE);

        if ($httpCode != 200) {
            $r = json_decode($data);
            echo 'data: {"error": "[ERROR]","message":"'.$r->error->message.'"}' . PHP_EOL;
        } else {
            $trimmed_data = trim($data); 
            if ($trimmed_data != '') {
                $response_array = json_decode($trimmed_data, true);
                $content = $response_array['choices'][0]['message']['content'];
                echo $content;
                ob_flush();
                flush();
            }
        }
        return strlen($data);
    },
];

curl_setopt_array($curl, $options);
$response = curl_exec($curl);

if ($response === false) {
    echo 'data: {"error": "[ERROR]","message":"'.curl_error($curl).'"}' . PHP_EOL;
}else{

}

    如果设置 "stream" => false 则得不到响应的原因是,整个代码设计为当 Stream 参数设置为 true

    通过以下修改,响应将作为一个整体进行处理,无论 stream 参数的值如何。

    试试这个:

    $API_KEY = "API_KEY_HERE";
    
    $model = 'gpt-3.5-turbo';
    $header = [
        "Authorization: Bearer " . $API_KEY,
        "Content-type: application/json",
    ];
    
    $temperature = 0.6;
    $frequency_penalty = 0;
    $presence_penalty= 0;
    $prompt = 'What can you help me with? For example: What do you suggest to keep me motivated?';
    
    $messages = array(
        array(
            "role" => "system",
            "content" => "Your name is 'JOHN DOE'. I want you to act as a motivational coach. I will provide you with some information about someone's goals and challenges, and it will be your job to come up with strategies that can help this person achieve their goals. This could involve providing positive affirmations, giving helpful advice or suggesting activities they can do to reach their end goal. if you don't understand the question, don't think too much, tell the user to be more specific with more details"
            ),
        array(
            "role" => "assistant",
            "content" => "Hello, I'm JOHN DOE, and I'm a motivational coach who loves helping people find their drive and achieve their goals. With years of experience in coaching and personal development, I've developed a unique approach to motivation that combines mindset, energy, and action."
        ),
        array(
            "role" => "user",
            "content" => $prompt
        )
    );
    
    $url = "https://api.openai.com/v1/chat/completions";
    
    $params = json_encode([
        "messages" => $messages,
        "model" => $model,
        "temperature" => $temperature,
        "max_tokens" => 1024,
        "frequency_penalty" => $frequency_penalty,
        "presence_penalty" => $presence_penalty,
        "stream" => false
    ]);
    
    $curl = curl_init($url);
    $options = [
        CURLOPT_POST => true,
        CURLOPT_HTTPHEADER => $header,
        CURLOPT_POSTFIELDS => $params,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_SSL_VERIFYPEER => false,
        CURLOPT_SSL_VERIFYHOST => 0,
    ];
    
    curl_setopt_array($curl, $options);
    $response = curl_exec($curl);
    
    if ($response === false) {
        echo 'data: {"error": "[ERROR]","message":"'.curl_error($curl).'"}' . PHP_EOL;
    }else{
        $response_array = json_decode($response, true);
        $content = $response_array['choices'][0]['message']['content'];
        echo $content;
    }
