Independent AI Studio

VONFAL AI

We build the engines, not just the apps.

An independent studio building intelligent products — and the engines underneath them. Our own models and computation where it matters, the best of the frontier platforms where they earn their place.

01 — What we ship

Live products. Push sideways.

Not demos — things in the world, each standing on computation we wrote ourselves. Drag, swipe, or use the arrows.

02 — Our engines

We name our engines because we built them.

Not wrappers, not integrations. Computation that runs where we put it, that no one else can retire or reprice.

Orrery
Computation
Computes the solar system from orbital mathematics. No feed to go down.
Ephemeris · Almanac
World cycles
Live cycles, and a history that checks its own forecasts against what actually happened.
EchoHex
The CMS
Our content engine, shipping its own updates to every site that runs on it.
Etch
Design system
One hairline and one notch, and every surface in the House is built from them.
Ember
Our own model
A model that is ours, on infrastructure that is ours. We decide when it changes.
03 — Our own intelligence

We build the brains, not just the apps that use them.

Ember — our own model

Ember is a model that is ours, on infrastructure that is ours — we decide when it changes, and the old one stays on the shelf. It is the proof of the thing we actually do.

◆We build small language models — local on your own hardware, or hosted and ready — tuned to the job, not rented by the token.
◆We build agents with their own memory and continuity, that carry a task across months instead of starting from zero each session.
◆We build the engines underneath the agents — the part most teams only rent, and the part that decides whether a system holds up.
The people behind Vonfal AI
The Sandbox — Our client platform

Build it with us.

A workspace where you build alongside us — your project taking shape in the open, instead of edits traded back and forth over email. Sign in, get an estimate, and watch it come together.
