Lunar Labs

A lab, not a startup.

We build a new kind of AI: models that learn you and stay, not chatbots you rent by the token. One tool ships today to fund the work. One is the work.

Artemis

Ships today

Stop paying frontier prices for answers a small model already knows.

Artemis sits beside your AI pipeline. It tries a local model first, verifies the answer, and escalates to the frontier only when it truly must — then shows you, line by line, the bill you stopped paying.

Every escalation trains the small model, so it deflects more every week. The audit is free; you keep the savings.

A mind that persists.

Not a model you rent by the token. A runtime that keeps its own time, holds its own state, and learns you overnight — on your hardware, private, still there in the morning.

We’ve measured it doing the one thing that matters: getting better at predicting you from your own life. The rest is what we’re building.
