You may pass a function as second argument to get real-time progression:

// $current_answer - incomplete answer
// $tokens - last tokens received
$final_answer = $conversation->ask($prompt, function ($current_answer, $tokens) {
    echo $tokens;
});

If you want to resume a previous conversation, you can retrieve its identifiers:

// Get current identifiers
$identifiers = $conversation->getIdentifiers();

// ...
// Resume conversation with $identifiers parameter
$conversation = $ai->resumeConversation($identifiers);

You can use a specific model:

$conversation = $ai->createConversation("bigcode/starcoder");

Default is OpenAssistant.

Useful to give a title to a conversation.

// Question asked: "Who's Einstein?"
// ...
$summary = $conversation->getSummary();
// Result: Famous genius mathematician.

HuggingChat share your conversations to improve the model. You can turn on/off data sharing:

$conversation->enableSharing(); // on

$conversation->disableSharing(); // off (module default)

$conversation->delete();

The code throws exceptions when it receives an error from HuggingChat. You can therefore use a try/catch block to handle errors.

Answers quality depends on the model you're using.
