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 seek what's good.

We pursue what we genuinely believe is good. We expect to be challenged and we change our minds when we're shown better reasoning. That’s how truth wins.

We build with intention.

The industry is racing to pour resources into scale. We take a different path. Through careful architecture and deliberate design, we build systems that use only what’s necessary to do the job well - nothing more.

We care for what we create.

What we create is not left to scale blindly. We guide, refine, and hold Deca (loosely but firmly) with care - so it remains useful, stable, and aligned with the people we affect.
