Altitude A2UI, running in this browser

Describe an interface. A fine-tuned model composes it from the Altitude design system and it renders below with the real components. The model runs entirely on your machine: nothing you type is sent anywhere.

starting

A 2.14 GB model downloads on first visit and is then stored on this machine, so an ordinary return visit skips it. Needs WebGPU and roughly 3 GB of memory, so a current laptop rather than a phone.

Greedy decoding, so the same request gives the same result.

The interface will appear here as the model writes it.
