It is kinda obvious, but maybe that's why it's not stated anywhere: each browser session will result in a download of 500 MB to ~1 GB, depending on your model selection. So, it's better to add a disclaimer if you end up using WebLLM in a customer-facing site.

This seems to be the demo:
I am getting:
WebGPUNotAvailableError: WebGPU is not supported in
your current environment, but it is necessary to
run the WebLLM engine.

For firefox you may need to enable `dom.webgpu.enabled` in `about:config`
It's on by default on Windows iirc - it's considered a potential security risk on Linux by Mozilla, so they ship it but it's turned off and it's up to the user to decide.
I think the reasoning is just because of how varied graphics drivers/stacks are on Linux compared to Windows/OSX and the attack surface been larger.

You can enable WebGPU support in Google Chrome by turning on hardware acceleration and activating the WebGPU flag. It Works.

I tried it and the experience was not great. I first enabled chrome://flags/#force-enable-webgpu-interop which did nothing. Next, I enabled chrome://flags/#enable-unsafe-webgpu which made some WebGPU demos work, but they all use my CPU's integrated GPU, which is worse than using no GPU acceleration at all. Next, I found out that there is a powerPreference: 'high-performance' option. It can be enabled with chrome://flags/#enable-webgpu-developer-features and I can now request a GPU with 'high-performance' power preference, although there is no way to check whether this actually selected the correct GPU, and it is useless to do it like that anyway, since no website actually sets this (experimental) option. Fortunately, there is the flag chrome://flags/#force-high-performance-gpu which should solve this, but it is not available for my platform. I have a fairly standard RTX 3060, but apparently, the most common GPU (according to the steam hardware survey) is not supported.
Unfortunately, Firefox does not work any better. After setting the flag dom.webgpu.enabled to true in about:config, a few WebGPU examples (e.g. https://webgpu.github.io/webgpu-samples/?sample=helloTriangl...) work, but many other examples crash the browser. And of course, Firefox can't select the correct GPU either.

Pretty much the same here with Edge,#enable-unsafe-webgpu got me the emulated swiftshader adapter, but only #force-high-performance-gpu made the dGPU appear in the adapter list of https://webgpureport.org/.

I really enjoy this engine. I’ve used it for personal projects, but it hasn’t been updated since Gemma 2. I suggest using Transformers.js instead these days.

Project is de facto dead, used it for many years and had to rip it out 6 months ago, don't waste your time.

We use the ONNX runtime for small models in the browser https://github.com/microsoft/onnxruntime

And ONNX is what Transformers.js uses as well, at least for the moment.

Yeah ONNX runtime or Burn-rs are great because they compile to wasm

There's, quietly, a llama.cpp WebGPU backend that works *great*.
Some hacking required, it's unsupported, a side project for one of the lead maintainers and someone in school.
Note of caution, llama.cpp isn't what it was, the grunt-level maintainers are left to their own devices. There's one key subsystem where things break regularly and the engineering is poor, and the "lead maintainer" is aggro and isn't really involved after delivering their big refactor that was DOA, other than telling people on issues he's never seen their repro himself. Carefully pick models you can support down to "I can patch around the Jinja template engine". Go through the same llama web server APIs. c.f. github / telosnex / fllama if you need a reference
(n.b. seeing peer comments, its much better than ONNX, ONNX never got within spitting distance of llama.cpp, my understanding from watching the LLM runtime is its used for Windows AI features so their models probably work great on Windows x Qualcomm. ONNX is great for smol models though, like VAD, a god send even.)
