# GPT-2/3 Tokenizer

GPT-2/3 byte pair encoder/decoder/tokenizer based on [@latitudegames/GPT-3-Encoder](https://github.com/latitudegames/GPT-3-Encoder) that works in the browser and Deno.

```js
import {encode, decode} from "https://deno.land/x/gpt_2_3_tokenizer@v0.0.2/mod.js";
let text = "hello world";
console.log(encode(text)); // [258, 18798, 995]
console.log(decode(encode(text))); // "hello world"
```
or:
```js
let mod = await import("https://deno.land/x/gpt_2_3_tokenizer@v0.0.2/mod.js");
mod.encode("hello world"); // [258, 18798, 995]
```
or to include it as a global variable in the browser:
```html
<script type=module>
  import tokenizer from "https://deno.land/x/gpt_2_3_tokenizer@v0.0.2/mod.js";
  window.tokenizer = tokenizer;
</script>
```
