ai2 Design System
Your agent writes the UI. This is the system it reads.
What it does
Every design system is complete until you need a small outline button in a warning tone. Then you are writing custom CSS, and the system you adopted for consistency is what makes you inconsistent. ai2 makes that button a prop. 51 MIT components, each with a real variant x tone x size matrix on one OKLCH token layer, light and dark from one source. 307 styled variants and 8 presets on top. Built for the machine writing your UI too: machine-readable axes, llms.txt, MCP. Free core, no account.

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
