Running llama2.c Examples

Here, we provide two examples of how to run llama2.c written in Rust using a Candle-compiled WASM binary and runtimes.

Pure Rust UI

To build and test the UI made in Rust you will need Trunk From the candle-wasm-examples/llama2-c directory run:

Download assets:

# Model and tokenizer

wget -c https://huggingface.co/spaces/lmz/candle-llama2/resolve/main/model.bin
wget -c https://huggingface.co/spaces/lmz/candle-llama2/resolve/main/tokenizer.json

Run hot reload server:

trunk serve --release --public-url / --port 8080

Vanilla JS and WebWorkers

To build and test the UI made in Vanilla JS and WebWorkers, first we need to build the WASM library:

sh build-lib.sh

This will bundle the library under ./build and we can import it inside our WebWorker like a normal JS module:

import init, { Model } from "./build/m.js";

The full example can be found under ./lib-example.html. All needed assets are fetched from the web, so no need to download anything. Finally, you can preview the example by running a local HTTP server. For example:

python -m http.server

Then open http://localhost:8000/lib-example.html in your browser.
