+You can then render a list of chat messages using a tokenizer's `apply_chat_template` method.

 ```js
 import { AutoTokenizer } from "@xenova/transformers";

+Notice how the entire chat is condensed into a single string. If you would instead like to return the tokenized version (i.e., a list of token IDs), you can use the following:
