# GPT-3-Encoder
Javascript BPE Encoder Decoder for GPT-2 / GPT-3

## 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 javascript implementation of OpenAI's original python encoder/decoder which can be found [here](https://github.com/openai/gpt-2)

## Install with npm

```
npm install gpt-3-encoder
```

## Usage

Compatible with Node >= 12

```js
const {encode, decode} = require('gpt-3-encoder')

const str = 'This is an example sentence to try encoding out on!'
const encoded = encode(str)
console.log('Encoded this string looks like: ', encoded)

console.log('We can look at each token and what it represents')
for(let token of encoded){
  console.log({token, string: decode([token])})
}

const decoded = decode(encoded)
console.log('We can decode it back into:\n', decoded)

```
