It doesn't seem so to me, either from the way it works or from what little of the code I've looked at...
But I don't have time to do more than the quick glance I just did at a few of the files of each and need to run, so hopefully someone cleverer than me who won't need as much time as me to answer the question could confirm while I'm afk

Fun demo but the model that's used seems to be pretty stupid:

That generous redefinition.of “humans” deals with only the error in the first sentence of the response; the rest is still not “broadly correct” even with it in place.
Blue Origin is built on taking ordinary humans to space. So is/was Virgin Galactic, though they are in a bit of a transitionary phase right now. SpaceX is also willing, they might even take you on a flyby of the moon if you bring money and patience (iirc the last customer lost patience). Basically just ring up your favorite multi-billionaire's space program. And while the estimated price would be correct for SpaceX, rumored prices for Blue Origin's New Shepard are only in the hundreds of thousands per seat
Edit: also the "but if you do that you are an astronaut, so it's still true that only astronauts can do that" loophole was closed when the FAA redefined the word astronaut in 2021. At least if you follow their definition of the word
There is a Prompt API in development that's available in both Chrome and Edge to give access to a local LLM. Chrome extensions have access to it and I believe websites can request access as part of an origin trial.
The model is fully managed by the browser. It's currently the Gemini Nano model on Chrome, and they are testing a version of the Gemma 3n model in beta channels. Edge uses phi-4-mini.
This demo only works if you have the webgpu feature "f16". You can find out if you have this by checking for the feature list in https://webgpureport.org/ .
The page itself can of course check for this but since f16 support is common they probably just didnt bother.
Does anyone know why all of these WebGPU LLM demos have you download the models to browser storage rather than letting you open a gguf already on your local drive? I have several models downloaded already that I would be interested in trying.
You can change this by changing settings, command line arguments, build flags, etc. But can’t really expect people to do this just to use your website.
You can open a file for performant access in all major browsers. It's the same API used for uploading files (<input type="file" />), but you can also just load them into memory and do stuff.
What's the performance of a model like vs an OpenAI API? What's the comparable here? Edit: I see it's same models locally that you'd run using Ollama or something else. So basically just constrained by the size of the model, GPU and perf of the machine.
Looks like this is a wrapper around: https://github.com/mlc-ai/web-llm
Which has a full web demo: https://chat.webllm.ai/
Is this correct?

Entirely correct, c.f. LLM.ts. The bit to Show HN here, is about ~40 lines of code. Simple Typescript MVP of calling the library.
(source: maintains an LLM client that works across MLC/llama.cpp/3P providers; author of sibling comment that misunderstood initially)
Thanks! (Have to admit your sibling comment confused the hell out of me.)

Are you kidding me? 500MB? And it’s that coherent?
It shows an interface of what could be.
It works on small Llama-3.2-1B model, specially for less powerfull GPU devices
The answer is still terrible for the model size. Maybe it's the 4 bit quantization, smaller models tend to react worse to that
For reference, [1] is what stock quen3-0.6B would answer. Not a perfect answer, but much better at nearly half the number of parameters
1: https://markdownpastebin.com/?id=7ad4ad9f325d4354a858480abdc...
It's likely the quantization on "Llama-3.2-1B-Instruct-q4f16_1-MLC". inference.net generated this more coherent answer: https://hst.sh/ovilewofox.md
It’s broadly correct, if you interpret ‘humans’ as ordinary humans who are not astronauts.

Am I missing something?
> Am I missing something?
Realistic expectations.
It seems to be working for some people. I'm just curious whether there was something I could change to make it work.
Well, at least it is more informative than an answer like "42".
fuck me it’s hacking the internet
I did this with mlc @ https://wiz.chat some time ago.
Warning: it has a llama 3.1 7b model and is around 4 gb. It needs either a GPU or a Macand works only on chrome
Very cool!
For some awesome examples of running different types of models in webgpu check out the examples folder here. https://github.com/huggingface/transformers.js
Model used: Llama 3.2 1B (small). Quality hould be similar with running Ollama app with same small model.
Does anyone know why all of these WebGPU LLM demos have you download the models to browser storage rather than letting you open a gguf already on your local drive? I have several models downloaded already that I would be interested in trying.
WebGPU's security model restricts direct file system access, requiring models to be loaded through fetch/cache APIs rather than local file paths.
Browsers are sandboxed away from user storage.
You can change this by changing settings, command line arguments, build flags, etc. But can’t really expect people to do this just to use your website.
You can open a file for performant access in all major browsers. It's the same API used for uploading files (<input type="file" />), but you can also just load them into memory and do stuff.
Sure, with the caveat that the file is specifically selected by the user.

Yes, its very similar to Ollama app, and Llama-3.2-1B model used
To have a gpu inference, you need a gpu. I have a demo that runs 8B llama on any computer with 4 gigs of ram
https://galqiwi.github.io/aqlm-rs/about.html
Any computer with a display has a GPU.
Sure, but integrated graphics usually lacks vram for LLM inference.
Which means that inference would be approximately the same speed (but compute offloaded) as the suggested CPU inference engine.
I've been following the development of WebGPU and its potential applications, and this demo is a great example of what's possible.
Cool idea but badly broken from a little testing.
Which model does the demo use?
Llama 3.2 1B
very cool. improvement would be if the input text box is always on screen, rather than having to manually scroll down as the screen fills.
Beware of opening this on mobile Internet.
Demo site is asking before download
Well, I am on a mobile right now, can someone maybe share anything about the performance?
Not everyone enjoys unlimited data plans, and 500 MB is schon a lot.
On my Android device works pretty fast.
But keep in mind that it's small Llama-3.2-1B model, specially for less powerfull GPU.
