Writing
On local AI.
Long-form pieces on the platform, the arguments, and the engineering. No news and no announcements — the things that stay true long enough to be worth writing down.
- What QVAC actually is Tether built an AI platform. The name is an acronym, the marketing is cosmic — underneath is a fairly specific piece of engineering.
- The case for local-first AI The argument is usually made about privacy. Privacy is the weakest version of it.
- Fine-tuning a model on your phone QVAC Fabric claims a billion-parameter fine-tune on a Galaxy S25 in eighty minutes. How that is possible, and what it changes.
