|
|
|
||
|
|
tiktoken is a [BPE](https://en.wikipedia.org/wiki/Byte_pair_encoding) tokeniser for use with
|
||
|
|
OpenAI's models. This is a pure JS port of the original tiktoken library.
|
||
|
|
|
||
|
|
Install the library from NPM:
|
||
|
|
|
||
|
|
```
|
||
|
|
npm install js-tiktoken
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Basic usage follows, which includes all the OpenAI encoders and ranks:
|
||
|
|
|
||
|
|
```typescript
|
||
|
|
import assert from "node:assert";
|
||
|
|
import { getEncoding, encodingForModel } from "js-tiktoken";
|
||
|
|
|
||
|
|
const enc = getEncoding("gpt2");
|
