What If History
Ask “What If?” and explore alternate timelines instantly
What it does
'What If History' lets you explore alternate timelines for any moment in history! Just ask a “What If” question and the app generates a structured alternate timeline showing immediate impact, long-term effects, and global consequences. Built as a lightweight web app and PWA, it works instantly with no signup and supports English, Hindi, and Hinglish inputs for a global audience. Ask questions like: • What if Product Hunt never existed? • What if The Epstein File never happened?

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15).

The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…
