WebGPU API is incredible! Just to show how incredible, there are versions of Stable Diffusion (AI image generation model) which can run in on a web-page. (Everything runs inside the browser with no need of server support).
A screenshot of the web stable diffusion project - which takes advantage of the WebGPU API to run a version of stable diffusion (in the browser with no server support needed).
While it's painfully slow (it's for me as I'm running it on my laptop), it runs in your browser (locally) and it's free and your data and information is safe (since you don't have to send it over the internet)
