microgpt.js

Runs a JavaScript version of the small microgpt.py script by Andrej Karpathy in a single web page. Suits developers and learners who want to read or try a tiny GPT in the browser.

About

What it is: This Space is a single web page that runs microgpt.js, a JavaScript version of the microgpt.py script by Andrej Karpathy. It lives in the browser, so there is nothing to install. The repository holds only a README and an index.html file, and the source says nothing more about what the page trains or generates.

Who it suits: It suits developers who want to read a compact GPT written in JavaScript, and learners who want to see a small language model work in a page.

Industry | Who uses it | How they use it | Example
Software | Web developers | Read how a small GPT is written in plain JavaScript | Open index.html and follow the code
Education | Students | See the pieces of a language model in a short program | Compare the page with the original script
Machine learning | Hobbyists | Try a tiny model without installing anything | Open the Space and watch what the page does

Skip it if you want a full-size model or a tool for real work, since the source describes only a small port.

Where to use it:

• A browser: open the Space's page on Hugging Face, with nothing to install
• A downloaded copy opened from index.html in a web browser on Windows, macOS or Linux

Use case | Who | What they get back
Reading the code | Developers | A short GPT implementation in JavaScript
Trying the page | Learners | A tiny model running in the browser
Comparing ports | Hobbyists | A JavaScript version to set beside the original script

How to set it up: The online copy needs nothing. To keep the files on your own computer, you need the following.

• Python with pip, used here to download the files
• The Hugging Face hub client, which the first step installs
• Any current web browser to open the page

1. Install the Hugging Face hub client.
2. Download the Space's files into a local folder.
3. Move into that folder.
4. Open index.html in a web browser.

pip install -U huggingface_hub
hf download webml-community/microgpt.js --repo-type space --local-dir microgpt.js
cd microgpt.js

How to use it: Open the Space's page, or open index.html from your copy. The source does not describe the page's controls, so follow its labels and read the code in index.html to see what it does.

Example: You open the page and watch what it does, then open index.html in an editor to follow the same steps in the code. The source gives no sample output or timing.

For newcomers and experts: If you are new, open the page first and then read the code in index.html. A short program is easier to follow than a large library.

If you know the field, this is a port of a minimal GPT script to JavaScript that runs in a page. The source does not state its model size, training data or whether it trains in the browser, so read the code to find out.

You open the page
The JavaScript code runs in your browser
The small GPT does its work on your device
You see the output on the page

Good to know: The source is short, so features and limits are not described.

• License: mit, as listed on Hugging Face
• Cost to run: no API key or paid service is named, and it uses your own device
• Data it reaches: the page says nothing about it, and it runs in your browser, so check the code for what it loads
• Not for: the source lists no exclusions, and it is a small port, not a full-size model
