We took the facts away from the AI.

Dates, figures, citations and records are computed by deterministic engines the model cannot override. It can phrase the answer. It can never invent the number.

0 fabricated dates or citations across 30 controlled trials, at every model size from 4.4 GB to 27 GB. Published, with a DOI.

Ask him something he shouldn't answer.

Seneca answers from a fixed public corpus. Pricing, customer names and unsourced figures are refused before the model ever sees the question.

Ask me anything about SOVERYN. I'll tell you when I can't source an answer.

He'll refuse. That's the point. A model that declines cleanly under pressure is the whole product — everything else on this page is a consequence of it.

Running in the world

Systems doing real work.

Not demos. The same engines, pointed at jobs where a fabricated answer — or a leaked one — is unacceptable.

In partner evaluation

Shepherd

FCC compliance for radio stations. Every filing deadline is computed from the rule and cited to its source, never generated by the model.

PondWright

Intake, CRM and estimating for a trade business. Our own reference customer — we run the business on it. It never quotes a price it can't stand behind.

History's Ledger

Primary-source history with a curator that cites or stops. Atticus won't invent a date, a figure or a quotation.

TGTHRmess

Specific needs, claimed by the people who offered to help. The model that turns a rambling paragraph into a claimable list runs on our own hardware — what a family writes in the worst week of their life never leaves the building.

The why

Three things wrong with AI, inverted.

It hallucinates

Truthful

Facts that matter come from deterministic engines the model can't override, each cited back to source. Not a prompt you hope holds — architecture.

It doesn't know you

Relational

Persistent memory and a continuous identity, recalled by meaning rather than recency. The model is a lease; the memory is the asset.

It isn't yours

Sovereign

Open-weight models on hardware you control. No cloud, no data egress, nothing anyone can revoke, throttle or rate-limit.

Published research

Measurements, with the harness released.

So you can reproduce them rather than trust us.

Honesty Is Architectural
Fabrication measured across a six-fold model-size range. Zero invented dates or citations — and one result that went against us.
Calibration Is Not Only in the Weights
1,680 trials. Two configuration flags move a model's self-knowledge further than a fifty-fold jump in parameters. Harness on GitHub.
A False Confession
An agent apologised for fabricating work it had genuinely done, twice, four hours apart. Contrition is not evidence.
Enterprise

Production-grade. Air-gap-capable. Entirely yours.

Built for environments where compliance is existential: healthcare (PHI), legal (privilege), defense and government (CUI/ITAR), financial services.

Fully local inference

Open-weight models on your own GPUs or CPU clusters. No cloud APIs.

Zero data egress

Prompts, documents, responses and embeddings stay inside your perimeter. Air-gap deployment supported.

Auditable at every layer

Inference, orchestration, memory, integration — yours to inspect and control.

Who we are

One engineer, in public.

Jon DeOliveira

SOVERYN is built by Jon DeOliveira, founder of Soveryn Intelligence LLC — thirty years in corporate leadership, sales and operations before writing a line of this stack. The systems on this page are running in production, and the research is published under his name.

Pricing
Per-deployment. Pilot engagements start with a scoped evaluation — ask and you'll get a real number, not a "contact sales" loop.
Stage
Pre-seed, self-funded. Development is paid for out of operating income, not a runway clock. Two systems live in daily use; Shepherd in partner evaluation with a radio group.

A demo is a working session, not a slide deck — bring a document, a deadline or a rulebook and we'll point the system at it.
