Introducing ArcQi

Quadratic self-attention is no longer a wall.

ArcQi Tech is dissolving the O(n²) bottleneck at the heart of self-attention. This single constraint defines the cost, length, and locality of every frontier model on Earth.

Frontier Model
The thesis

Every frontier model is paying a quadratic tax.

Self-attention is the engine of the modern transformer. It is also its most expensive part.

Attention scales with the square of the context length. Double the window, quadruple the compute. This is the wall.

ArcQi's research collapses this scaling law. Sub-quadratic attention with preserved expressivity. A structural rewrite of the operation itself.

The same workload, two scaling laws.

What it unlocks

Three consequences, cascading.

When the cost of attention bends, everything downstream bends with it. The token economy, the shape of context, the geography of inference.

A book becomes a sentence.

Million-token windows stop being a premium tier. They become the default unit of thought: entire codebases, legal corpora, patient histories held in working memory, reasoned over end-to-end.

→ Context becomes free

The token economy inverts.

When attention scales gently, inference economics break in the customer's favor. The marginal cost of a long conversation collapses. Agents that loop, reflect, and revise become viable at scale.

→ Agents that finish

Intelligence comes home.

Intelligent models, built with long context in mind, reasoning on the workstation, the laptop, the edge device. Private by physics. The hospital, the law firm, the financial institution, the lab. All on their own machines, under their own roof.

→ Your hardware, your model
The next leap in AI won't come from more compute.
It will come from a better foundation.
Founding memo, 2026
The approach

Engineered against the hardware, not around it.

Our work is research-first and IP-protected. The summary below is public; selective disclosure is available to partners under NDA.

Complexity
Sub-quadratic in sequence length, with preserved expressivity.
Substrate
Kernel-fused, memory-hierarchy aware. Designed for the GPU you already own. And the one that comes next.
Composability
Engineered for compatibility with existing transformer pretraining pipelines.
Posture
A small team. A single problem. A multi-year horizon.
Status
Architecture validated. Scaling in progress.
