If you're building a world model —
you already know what's missing.
Friction. We thought of it too.
// 01 · The Idea
World models are not just bigger LLMs.
They are systems that understand
what happens when things interact.
And the moment two things interact
in the physical world —
friction exists. No exceptions.
Current AI skips this entirely.
It predicts. It generates. It flows.
But it never resists.
If you're building a world model,
you're building friction back in.
These domains already say that.
01
Frictial
Friction + material. The property of a surface that resists motion. In the context of world models, it names the missing layer — physical constraint that makes intelligence grounded and real.
02
Gritray
Grit + Ray + Array. Texture and resistance rendered into light. Ray tracing is how world models reconstruct physical reality. Grit is what makes that reality non-trivial.
03
Why Together
Frictial names the concept. Gritray names the method. One is the thesis, one is the technology. Own both and you own the whole story.

Product Domain// 03 · Who This Is For
You're building a world model.
You've probably already asked yourself —
how do we make the model understand
that actions have weight?
That movement costs something?
That the physical world pushes back?
That's friction. That's what these domains are about.
If we thought of it the same way —
your users will too.
