Vertical
Inference
System intelligence beyond the model.
The application, model runtime and live inference state become one programmable system.
Vertical Inference is an application architecture in which model execution becomes resident application state. Ordinary code governs how intelligence retrieves, reasons, acts and continues while it is underway.
Lloyal is the platform for building and deploying this architecture—from local applications to frontier compute.

Two real runs. One flagship application built on Lloyal, spanning both extremes.
01 / THE HARNESS
The harness is the intelligent application.
You already know how to build this: MVC, with a live LLM as the Model. Product surfaces are the Views. The harness is the Controller—ordinary TypeScript defining how the application's intelligence collaborates, acts, recovers and continues. Beneath it, a resident LLM holds the live generative state.
The model supplies the intelligence. The harness supplies the institution.
This is what the Controller looks like:
export function* incidentHarness(incident) {
const evidence = yield* parallel([
inspectTelemetry(incident),
searchServiceHistory(incident),
reviewTechnicalManuals(incident),
]);
const assessment = yield* reconcile(evidence);
if (assessment.requiresApproval) {
return yield* requestOperatorDecision(assessment);
}
return yield* proposeRemediation(assessment);
}
02 / AGENTAPPS
Intelligence needs contact with reality.
AgentApps connect the harness to documents, browsers, feeds, enterprise systems and tools. They can retrieve evidence, observe changing state and perform authorised actions. The harness determines when they run, which live lineage receives what they return and what consequence is permitted.
Retrieve
Acquire and evaluate evidence across search, corpora, documents and databases.
Observe
Read the world as it changes through browsers, feeds, telemetry and application state.
Act
Produce permitted consequence through computer use, workflows, APIs and operational tools.
AgentApps are signed, portable capability contracts combining Skills · Live Sources · Tools · Grants · Protocol
