Deca

AI will touch every problem worth solving. Deca builds frontier models that are just as capable as they are efficient.

What we believe

Frontier intelligence, designed from the ground up to be efficient.

You shape what we become
Industry
Deca
Compute discipline is safety
We change our minds when we're wrong.

We expect to be challenged and we change our minds when we're shown better reasoning. That's how truth wins. We want Deca to do the same.

We think harder, not bigger.

The industry assumes bigger always wins. We're skeptical. More compute can increase capability, but it also increases opacity, cost, and dependency. Constraints force harder thinking about what actually matters.

We trust judgment over rules.

Most AI safety builds exhaustive prohibition lists. We keep boundaries narrow and trust judgment everywhere else. A system that treats everything as dangerous can't help anyone with anything.
