+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 which can be found [here](https://github.com/openai/gpt-2), the main source of inspiration for writing this encoder was the NodeJS version of this encoder, found [here](https://github.com/latitudegames/GPT-3-Encoder.
 
 This specific encoder is used in one of my [WordPress plugins](https://coderevolution.ro), to count the number of tokens a string will use when sent to OpenAI API.
