AI Systems
AI Systems are the unit of execution in Modulos. An AI System defines a governance scope and contains the frameworks, Controls, Evidence, and monetary risk quantification needed to make that scope auditable.
What this is
An AI System is a boundary that keeps governance work consistent:
- one scope statement an auditor can understand
- one set of frameworks and Requirements that apply to that scope
- one audit trail for Controls, Evidence, reviews, and risk decisions
AI Systems and the organization AI System
The AI Registry lists two kinds of entry, distinguished by Type: AI Application or Organization. They map to how compliance and audits work in practice.
AI Systems
An AI System governs one deployed AI system or use case in its real deployment context. The AI Registry lists it with Type AI Application.
An AI system is not just a model. It includes the full socio-technical system that produces and uses AI outputs.
AI system
The model is the centre. The system is everything around it.
Inputs
DataTraining data, input data, labels, feedback
InfrastructureCloud, third parties, model providers
InterfacesAPI, UI, integrations
AI system
Outputs that influence real decisions
The bounded technical artifact under governance.
Model or modelsFoundation model, fine-tune, classifier
Inference & orchestrationPrompting, retrieval, routing, post-processing
Operations
Humans in the loopOperators, reviewers, escalation paths
MonitoringDrift, quality, incidents
Downstream decisionsBusiness process, automation, approvals
Documentation & controlsPolicies, evals, evidence
An AI system includes the model, the surrounding pipeline, the human processes, and the environment where outputs drive real decisions.
AI system definitions
EU AI Act definition:
"AI system" means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.
NIST AI RMF definition, adapted from OECD:
The AI RMF refers to an AI system as an engineered or machine-based system that can, for a given set of objectives, generate outputs such as predictions, recommendations, or decisions influencing real or virtual environments. AI systems are designed to operate with varying levels of autonomy.
AI Systems are the default choice for frameworks that are system-scoped, such as the EU AI Act.
The organization AI System
One organization AI System holds organization-wide governance programs and management systems:
- policies and processes that apply across teams
- shared Controls that support multiple compliance programs
- certification-style audits where scope is the organization, not one system
It is listed with Type Organization in the AI Registry and is the home of organization-scope frameworks (OFF-x) such as ISO 42001 and ISO 27001.
The AI Registry does not create new organization AI Systems; if your organization does not have one yet, contact Modulos support before rolling out organization-scope frameworks.

Who can do what
Permissions
- AI System Owners configure the AI System, assign AI System roles, and manage settings.
- Editors implement Controls, attach Evidence, and keep work items up to date.
- Viewers have read-only access focused on traceability.
Organization admins typically have full administrative access across AI Systems in the organization. Use AI System roles to grant the minimum needed access to non-admins and to preserve separation of duties.
How it works
AI Systems unify execution across governance areas: governance, risk quantification, and runtime inspection all live inside the same scope boundary.

Audit trail
Projects keep scope, execution, and traceability in one place so audits can follow decisions back to evidence.
That shared structure is what allows traceable exports and audit-ready reviews.
What lives in an AI System
Depending on your organization setup, an AI System may include:
- frameworks, Requirements, Controls, and Evidence
- risks and monetary quantification runs
- runtime inspection Sources, tests, schedules, and results
- assets and supporting documents
- notifications and object-level comments and logs
How to use it
1
Pick the right scope
Register an AI System for system-scoped compliance; management-system frameworks attach to the organization AI System
2
Write a scope statement
Describe what is in scope in plain language an auditor can validate
3
Add frameworks
Select the regulations and standards that apply to this scope
4
Assign roles
Set owners, editors, and viewers early to preserve separation of duties
5
Execute and monitor
Implement Controls, attach Evidence, quantify top risks, and run testing over time
Important considerations
- Keep AI Systems narrow. Registering one AI System per deployed system or use case keeps Evidence and risk quantification defensible.
- Treat the AI System description as your scope statement. It should survive staff turnover and audit scrutiny.
- Reserve the organization AI System for shared Controls and policies.
