omni-tokenizer v2.0.1

Omni Tokenizer

A Node based tokenizer for open source models hosted on HuggingFace.

Specify the model repo and the tokenizer configuration files will be automatically downloaded from HuggingFace and used to encode provided text.

This has only been tested on Mixtral, Mistral, and Gemma models!! Please submit issues if you encounter problems with other models or feel free to contribute.

Installation

npm install omni-tokenizer

const { Tokenizer } = require('../src/tokenizer');

const tokenizer = new Tokenizer('mistralai/Mixtral-8x7B-Instruct-v0.1');

await tokenizer.load();

const text = 'hey there how are you doing';
const encoding: number[] = await tokenizer.encode(text);

console.log('Token Count', encoding.length);

const decoded: string = await tokenizer.decode(encoding);

console.log(decoded); // 'hey there how are you doing'
