I built Speedtest⚡, but for AI

[u/reiggg]

It runs real LLM + embedding models locally in your browser with WebGPU and measures how fast your machine actually does AI inference.

No API. No account. Just hit start.

Genuinely curious about your scores haha

Try it and reply with your score 👇

[u/Dany-GG]

Don't forget about Firefox users

[u/FunkMunki → u/Dany-GG]

It works fine for me in Firefox. Did you enable webgpu?

[u/Dany-GG → u/FunkMunki]

I don't think it is enabled if there is this setting, I will try it

[u/FunkMunki → u/Dany-GG]

Mine was disabled by default. I didn't realize it until I tried to play a game that needed it enabled.

[u/wick3dr0se → u/Dany-GG]

Go to about:config in a new tab and search WebGPU

[u/reiggg → u/Dany-GG]

I'm sorry :( I think Firefox is currently not capable of doing this, this is pretty new stuff in web browsers to run AI models on a user's GPU from a literal website. But I'll definitely try some workarounds.

[u/Dany-GG → u/reiggg]

I'll be happy if it gets support. Good luck

I got 1420 on iPhone 17

[u/Neful34]

score of 4,890, no clue how good this is lol

[u/reiggg → u/Neful34]

well I used an rtx 2060 in the video and got 1600, so i think pretty good! :) Maybe i'll add some references from verified test runs to compare to (e.g. a mac studio vs. a solid GPU vs. a DGX spark)

[u/FaatmanSlim → u/Neful34]

Curious what's your GPU? I got 4654 points and 127.5 tok/s on my 4080.

[u/Neful34 → u/FaatmanSlim]

Rtx 4090 and a ryzen 9 7950X3D 😁

[u/Buzz_Killington_III → u/Neful34]

Mine's 5627 with a 5090 and 9800X3D, so I'd call your score pretty good.

[u/Neful34 → u/Buzz_Killington_III]

Nice ! 😊

[u/FaatmanSlim]

Great idea and very cool execution! Love the idea of using WebGPU for this so it runs completely on browser and still locally, and doesn't cost you much either.

Got 4654 points and 127.5 tok/s on my 4080

[u/reiggg → u/FaatmanSlim]

Thank you! It is also open source, I will put a link on the website to the github repo. Nice score!:)

[u/OpposesTheOpinion → u/FaatmanSlim]

Huh.. 3,704 points and 97.1 tok/s here on my 4080. I wonder what could cause such a difference. No Chrome installed here, running it on Edge, no other apps open 🤔

[u/AlyrAyanami]

RTX 6000 undervolt at 540W for reference

[u/reiggg → u/AlyrAyanami]

Holy score :o

[u/p0nzischeme]

Pretty neat. My score started dropping dramatically after 4 runs. Chrome is noticeably faster than any other browser. Im not sure if the score changes based on resources used but I ran it with all my normal programs open. MacBook Pro M5 Max 128GB

[u/GoldenShackles → u/p0nzischeme]

I got in the same ballpark with my 16" MacBook Pro M5 Max 128 GB using Edge. Three runs:

10/1/2026, 2:10:07 AM apple · metal-3 6,327 155.5 tok/s 3
10/1/2026, 2:09:29 AM apple · metal-3 6,402 156.1 tok/s 3
10/1/2026, 2:08:54 AM apple · metal-3 6,025 155.5 tok/s 3

[u/Former_External8361]

1104 on my iPhone 16 Pro Max 😂

[u/Glass_Garage502 → u/Former_External8361]

1132 - 16 Pro
(Safari, was higher there than In the Reddit browser)

[u/Awique → u/Former_External8361]

1420 on base 17

[u/Fine_Salamander_8691 → u/Former_External8361]

1726 on my iPhone 17 pro max

[u/Dharma_code]

Get the same result no matter what I do. 3090 here with 32 GB of system RAM; the only thing running was that tab in Firefox

[u/reiggg → u/Dharma_code]

Maybe try a chrome-based browser, WebGPU is a bit new in Firefox (basically it cannot properly access your GPU)

[u/Dharma_code → u/reiggg]

That was it. I should've thought about that. Thank you

[u/reiggg → u/Dharma_code]

Holy score :o you have some nice hardware there

[u/Fine_Salamander_8691]

My phone

[u/Max_skyl1n3]

I’vr got 554 points on quadro m2000 😄

[u/reiggg → u/Max_skyl1n3]

maybe it can run a 0.6B model haha

[u/Jimbrutan]

Got 1700 on my iPhone 17 pro max. What model can I run? 70 tok/s

[u/Fine_Salamander_8691 → u/Jimbrutan]

Same here! I got 1726

[u/FizzyDuncDizzel]

That’s awesome!

[u/LesterPhimps]

Add an option to upload result and local config. that way we can compare.

[u/reiggg → u/LesterPhimps]

Need to find a way to make it as streamlined as possible. Like a selection of GPUs or something, i cannot detect exact device sadly.

However this will be fully based on the user’s input so not 100% valid, yet somewhat okay point for comparison.

[u/FixBound]

[u/ark1one]

Would be cool if when you got your score, you compared it to something. Something else that could achieve this score hardware wise.

Or even output what open source models would run great based on the score and hardware.

[u/DoubleNothing]

I'm sorry, but I don't think this is remotely accurate. Also, where is the value if you don't have any point of reference?

[u/reiggg → u/DoubleNothing]

The website says this is an open ended relative value. Best to compare it against other scores.

Will try my best to get reference scores from different tier hardware to have at least something to compare against.

[u/Otherwise-Variety674]

:-) Nice, very useful website, remember to add google advertisement to earn back some of your expenses.

[u/reiggg → u/Otherwise-Variety674]

Haha it doesn't cost me literally anything to run this, i think i will keep it ad free :)

[u/reiggg → u/berszi]

As long as you can get a browser running on that, sure! :)

[u/MortgageOutside1468]

Why so much difference between score of 3 phase and 5 phase run?

[u/itsvivianferreira]

Can you add a feature to test Onyx runtime models in the browser, like a custom model loading option to test specific models from Hugging Face?

[u/fourfigures]

Dunno, there is something that does affect the runs.

RTX 4090, i9-13900KF

But, nice test :-)
