My #WebAI Summit talk "Built-in AI in the wild: A Mastodon translation success story" is now live: youtu.be/-l2BUUdBDS8?.... I had so much fun giving this talk, and in it I teach you the German word for waving back at someone who wasn't waving at you: Fremdwinkzurückwinkungspeinlichkeit 🇩🇪 👋 😳.

🤯 Just updated my depth demo for #LiteRTJS to create 3D point cloud of webcam feed in real-time entirely client side! ✨ As this is #WebAI everything is running entirely locally in browser via #WebGPU using #Qualcomm DepthAnythingV2 model. Also means you can try it yourself here: lnkd.in/gDutNjjC

✨This year Google launched LiteRT.js - a client side Web AI runtime that can run AI models in browser! To learn ropes I found a depth model from #Qualcomm that runs in
Chrome via #WebGPU! Greener pixels mean closer to the webcam, and bluer pixels are further away.

Just used #Gemini3 to redesign my website that I've not had time to touch as so busy with #WebAI ;-) Is it perfect? No. Is it an inspiring start that I can fix up? Hell yeah! Thanks @developers.google.com. Demo: codepen.io/jasonmayes/f...

Sound on! Just made a real-time MP3 visualizer in JS with #Antigravity! I decided to pivot to diving deeper with Antigravity (a brand new agentic development platform) by Google to work on something longer than 60 seconds. This was the result: www.linkedin.com/feed/update/...

Wow. 🤯 Mind blown. Used Gemini 3 to create this retro flight game complete with collision detection and retro sounds that react to speed of plane. How long did it take? About 120 seconds. Vanilla JavaScript, fully functional on first try, I am impressed. Try: codepen.io/jasonmayes/p...

Grinding my gears: Folk creating new standards (#TOON) vs using existing correctly (#JSON). Going virial right now is not an apples to apples comparison. Can write VALID JSON in just 26 tokens (< TOONs 35). TOON is 34.6% worse here.

People were asking me how to cache the #MediaPipe Gemma 2 #WebAI model in browser so that the 2nd page load is fast (as 2.5 GB download). Turns out it was a little tricky due to upper limits of how large a blob can be in browser cache, so I made a library to help you out: github.com/jasonmayes/w...
