HuggingChat client

This is an unofficial PHP client for HuggingChat (OpenAssistant's LLaMA model).

HuggingChat API is evolving fast with recurring breaking changes. I try to keep up with it, but it may not always work as expected. Feel free to open an issue if you encounter any problem.

Installation

composer require maximerenou/hugging-chat

Demo

Run examples/chat.php to test it.

Usage

use MaximeRenou\HuggingChat\Client as HuggingChat;
use MaximeRenou\HuggingChat\Prompt;

$ai = new HuggingChat();

$conversation = $ai->createConversation();

// $answer - full answer
$answer = $conversation->ask(new Prompt("Hello World"));

Real-time / progressive answer

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;
});

Resume a conversation

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);

Use another model

You can use a specific model:

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

Default is OpenAssistant.

Generate a conversation's summary

Useful to give a title to a conversation.

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

Turn on/off data sharing

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

$conversation->enableSharing(); // on

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

Delete a conversation

$conversation->delete();

Handle HuggingChat errors

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

Answers are sometimes malformed (or dumb)

Answers quality depends on the model you're using.
