PHP BPE Encoder Decoder for GPT-2/GPT-3

About
-----

[](#about)

GPT-2 and GPT-3 use byte pair encoding to turn text into a series of integers to feed into the model. This is a PHP implementation of OpenAI's original python encoder/decoder which can be found [here](https://github.com/openai/gpt-2).

Get Started
-----------

[](#get-started)

> Requires [PHP 7.4+](https://php.net/releases/)

Install GPT-3-Encoder via the [Composer](https://getcomposer.org/) package manager

```
composer require rahul900day/gpt-3-encoder
```

Usage
-----

[](#usage)

Encoding a text to tokens

```
use Rahul900day\Gpt3Encoder\Encoder;

Encoder::encode("Your prompt.");
```

Decoding to text from tokens

```
use Rahul900day\Gpt3Encoder\Encoder;

Encoder::decode([8582, 242, 98]);
```
