This web sample demonstrates how to use the LLM Inference API to run common text-to-text generation tasks like information retrieval, email drafting, and document summarization, on web.

• A browser with WebGPU support (eg. Chrome on macOS or Windows).

Follow the following instructions to run the sample on your device:

1. Make a folder for the task, named as llm_task, and copy the index.html and index.js files into your llm_task folder.
2. Download a pre-converted Gemma model, like Gemma 2 2B (LiteRT 2b-it-gpu-int8) or the smaller Gemma 3 1B. Alternatively, you can convert an external LLM (Phi-2, Falcon, or StableLM) following the guide (only gpu backend is currently supported), into the llm_task folder.
3. In your index.js file, update modelFileName with your model file's name.
4. Run python3 -m http.server 8000 under the llm_task folder to host the three files (or python -m SimpleHTTPServer 8000 for older python versions).
5. Open localhost:8000 in Chrome. Then the button on the webpage will be enabled when the task is ready (~10 seconds).
