Private AI architecture designed around your environment.

CuxtonAI builds AI architecture that begins with where data is allowed to be not where it is most convenient to process it. Deployment model, model choice and integration design are determined by your organisation's data sensitivity, regulatory context and technical constraints.

Enterprise AI cannot rely on public black-box endpoints. Explore the 4 deployment postures engineered around your data sensitivity, network boundaries, and statutory regulatory requirements.

Physical Air-Gap

On-Premise Bare-Metal

AI infrastructure runs entirely inside your physical datacenter on client-owned appliances. Prompts, retrieval documents, and weights never cross your facility's network boundary.

Target Environment:

National Defense, Central Banks, Intelligence, Sovereign Wealth & Critical Infrastructure

  • Guarantees that no external entity can inspect, intercept, or train upon institutional prompts
  • Full compatibility with statutory national security air-gapping mandates
  • Direct hardware optimization against existing on-premise compute and storage fabrics

Governance & Operations Reality

Requires internal hardware procurement, physical space, power, cooling, and on-site hardware maintenance management.

A layered architecture that maintains control at every level.

Every layer from data connectivity to autonomous agent execution is engineered with the organisation's governance requirements in mind. AI does not bypass security boundaries, compromise data sovereignty, or override institutional permissions.

Institutional Systems & Identity Management

Integrates directly with your existing enterprise infrastructure, single sign-on (SSO), directory services, and network boundaries. AI systems respect established access hierarchies rather than overriding them, ensuring no unauthorized privilege elevation.

Controlled Data & Knowledge Mesh

Connects operational databases, document repositories, and institutional knowledge lakes through secure, permission-aware retrieval pipelines. Data remains encrypted within approved boundaries, and retrieval strictly enforces user-level access rights.

Private AI Compute Tier

Executes approved open-weight models, customized architectures, or private API endpoints within isolated compute enclaves. Cuxton configures compute location based on your latency, regulatory residency, and data sensitivity requirements.

Specialized AI Applications & Agent Swarms

Task-bounded agents, analytical assistants, and automation pipelines presented through approved internal interfaces, existing tools, or bespoke front-ends. High-consequence actions incorporate mandatory human approval gates.

Native IAM & RBAC Inheritance

AI queries dynamically inherit the requesting user's security context. If a user cannot access a file directly, the AI model cannot access it either.

Zero Privilege Escalation

Strict logical barriers prevent model outputs or prompt injections from escalating system permissions beyond pre-approved scopes.

Cryptographic Attribution & Audit

Every prompt, vector retrieval path, model decision, and workflow action is recorded with full auditability for continuous compliance.

We don't have a preferred vendor.
The requirement picks the model.

Every workload has constraints before it has a model: where the data is allowed to sit, how quickly the answer has to come back, how exactly the output has to be structured, and what it can cost to run. Those four things decide the architecture.

  • Data classificationWhere the data is allowed to be processed.
  • Latency budgetHow fast the answer has to come back.
  • Output precisionHow strictly the result must match a format.
  • Cost shapeWhether spend is capital, per-call, or mixed.

Four workloads we see often. Each one is decided by its constraint, not by preference.

01

Open-weight, self-hosted

Weights you hold, running on hardware you control.

  • Data cannot leave your perimeter, under any circumstance
  • The deployment has to survive vendor deprecation and API changes
  • Auditors need to inspect the full inference path
02

Commercial API, under contract

Frontier capability, used only where the contract permits it.

  • The task genuinely needs frontier reasoning or broad world knowledge
  • A zero-retention agreement is in place and the data classification allows it
  • Traffic can run over private peering rather than the public internet
03

Fine-tuned for the domain

A smaller model taught your vocabulary and output format.

  • Output has to follow an internal schema or house format every time
  • The domain has terminology a general model reliably gets wrong
  • The same task runs at volume and needs to stay inexpensive
04

Routed ensemble

Small models take the routine work; larger ones take the exceptions.

  • Volume is high and most requests are genuinely routine
  • High-consequence output should be checked by a second model before it ships
  • Cost should track difficulty rather than a flat frontier rate

Most deployments end up using more than one of these. Talk through your constraints and we'll tell you which ones apply including where you don't need us.

Governance principles
engineered into every deployment.

AI governance is not an afterthought. It is enforced at the network, model, and application boundary before any system processes institutional information.
