About this version
A minimalistic JavaScript implementation of the Jinja templating engine, specifically designed for parsing and rendering ML chat templates.
First, install the templates and hub packages:
npm i @huggingface/templates
npm i @huggingface/hubYou can then load a tokenizer from the Hugging Face Hub and render a list of chat messages, as follows:
import { Template } from "@huggingface/templates";
import { downloadFile } from "@huggingface/hub";
const config = await (
await downloadFile({
repo: "mistralai/Mistral-7B-Instruct-v0.1",
path: "tokenizer_config.json",
})
).json();
const chat = [
{ role: "user", content: "Hello, how are you?" },
{ role: "assistant", content: "I'm doing great. How can I help you today?" },
{ role: "user", content: "I'd like to show off how chat templating works!" },
];
const template = new Template(config.chat_template);
const result = template.render({
messages: chat,
bos_token: config.bos_token,
eos_token: config.eos_token,
});
// "<s>[INST] Hello, how are you? [/INST]I'm doing great. How can I help you today?</s> [INST] I'd like to show off how chat templating works! [/INST]"First, install the @huggingface/templates and @xenova/transformers packages:
npm i @huggingface/templates
npm i @xenova/transformersimport { AutoTokenizer } from "@xenova/transformers";
const tokenizer = await AutoTokenizer.from_pretrained("mistralai/Mistral-7B-Instruct-v0.1");
const chat = [
{ role: "user", content: "Hello, how are you?" },
{ role: "assistant", content: "I'm doing great. How can I help you today?" },
{ role: "user", content: "I'd like to show off how chat templating works!" },
];
const text = tokenizer.apply_chat_template(chat, { tokenize: false });
// "<s>[INST] Hello, how are you? [/INST]I'm doing great. How can I help you today?</s> [INST] I'd like to show off how chat templating works! [/INST]"
const input_ids = tokenizer.apply_chat_template(chat, { tokenize: true, return_tensor: false });
