KStone OS · AI Architecture

Two AI engines.
One governance layer.

KStone routes every task to the right intelligence. Sensitive, regulated, or proprietary work runs locally. Frontier reasoning taps the world's strongest third-party LLMs. The executive never has to choose.

Engine 01

Local AI

For sensitive data.

  • On-device or on-prem inference — data never leaves the perimeter.
  • Tuned for finance, legal, HR, and board-level workflows.
  • Air-gapped deployments available for regulated industries.
  • Audit trail on every prompt, response, and decision.
Engine 02

Frontier LLMs

For complex reasoning.

  • Best-in-class third-party models routed by task complexity.
  • Strategic synthesis, scenario modeling, deep research.
  • Privacy-preserving routing — only non-sensitive context leaves.
  • Model-agnostic. Always upgrading to what's strongest.

Layered Executive Intelligence

AI proposes · Humans decide
01

Data Intake

Structured ingestion across docs, systems, and signals.

02

AI Intelligence

Local + frontier routing. The right model, every time.

03

Decision Support

Options surfaced with tradeoffs, risks, and confidence.

04

Human Governance

AI proposes. The executive decides. Every action logged.

Design Principle: AI proposes. Humans decide. Every layer is auditable, reversible, and governed by the executive — not the system.

01

Sovereign by default

Your data stays yours. Routing rules enforced at the edge, not the cloud.

02

Model-agnostic

We pick the strongest model for the task — and switch the day a better one ships.

03

Audit-grade

Every prompt, response, and override is logged for compliance and review.

04

Reversible actions

Nothing material happens without an executive in the loop. Always.
