For governments and enterprises

Sovereign AI for
Sovereign Industries.

HAQQ’s sovereign AI engines let you use frontier AI models at a lower cost, without compromising the sovereignty, security or safety of your data.

Talk to HAQQ See how it works

Never again compromise performance for sovereignty.

Problem

Host it yourself and lose performance, or use the frontier and lose control.

Open-weight models run on your own infrastructure but fall behind the frontier on complex work. Frontier models reason better, but sending them sensitive records puts residency and confidentiality at risk.

Solution

Run both, on your rules.

Caesar prepares the task and retrieves the relevant material before asking a model to reason. Your data never reaches the frontier models.

Applications

Give your teams a place to use it.

Connect an existing application, build a new one with your developers, or work with HAQQ on the experience your team needs. The interface, integrations and availability are agreed as part of the deployment.

How Caesar works

Your data never reaches the frontier models.

Get intelligence that beats the frontier at a lower cost, while you keep your sovereignty. The compromise doesn’t exist. As the frontier evolves, we will outstand it.

See what happens behind the answer

We benchmark Caesar on quality per dollar and reliability.

Industry by industry, against the newest models: how much quality each dollar buys, and how rarely a model answers wrongly when it is unsure. The neon ring marks Caesar’s target, not a measured result.

Justinian proved it in law. Caesar takes it further.

HAQQ built Justinian for legal work: research under the right jurisdiction, drafting from a firm’s own precedents and review with sources the lawyer can inspect. Caesar is the next generation of that engine, built to apply the same approach to the work of other industries.

Peaks at dawn receding into mist: the nearest lit gold at its summit, the second half in shadow.

Generation 1 · The legal generation

Justinian

Justinian powers HAQQ’s legal products. Its context is the client, the matter, the law and the firm’s own work.

Generation 2 · More powerful, for any industry

Caesar

Caesar extends the engine beyond law. A deployment connects the organization’s own records, procedures and software to the tasks its people need to complete.

Explore HAQQ Legal AI See how we evaluate the work

Sovereignty means owning every layer.

Caesar is the whole architecture. Optimized for government deployment, it wraps every layer of the chain in sovereignty, from the energy and hardware it runs on to your data, its intelligence and the applications your people use.

“Review this policy change against our current procedures. Show what needs attention and who should review it.”

Illustrative workflow, not a live system response. The result depends on the connected sources and agreed configuration.

Energy

The power behind every deployment.

SovereignYour deployment runs on the power of the site you choose.

Deployment

Choose where Caesar lives.

Sovereignty means deciding where information is stored and processed, who can use it and whether a request may reach an outside model. Choose the environment for Caesar and set those rules before the work begins.

HAQQ Cloud

HAQQ manages the hosting environment. Agree the region, data handling and permitted models as part of the deployment.

Upfront: No hardware or setup to fund
Best for: The fastest start

On-premise

Run Caesar on your own infrastructure. Use locally hosted models for work that must stay inside the boundary, with external calls enabled only where permitted.

Upfront: Hardware you buy and own
Best for: Full control of data and compute

API and MCP · Early access

Connect through the API

An API lets your software send a task to Caesar and receive the result. Your developers can put research, document comparison or drafting inside the application your team uses.

Discuss applications and API access

Hosting and model access are separate choices. A locally hosted engine can use local models, permitted external models, or a combination agreed for the deployment.

Earn your regulators’ trust with security built in.

Caesar is built to the security and AI-governance standards regulators expect, and every call is logged for audit.

Why not use a general AI model directly?

An AI model supplies reasoning and generation. Putting it to work in your institution also requires the right records, permissions, tools, workflow history and review steps. Caesar supplies that system around the model. You can build those layers yourself; HAQQ offers an engine you can deploy and configure around your work.

Do we need to replace our existing software?

Caesar is designed to connect to existing systems. We agree which records it can read, which actions it can take and which integrations need work. You can use an appropriate HAQQ application, build your own interface or integrate Caesar into an existing application.

What do we need to get started?

A clear first task, a person responsible for reviewing it and access to the relevant source material. HAQQ works with your team to define the connections, hosting, permissions and acceptance criteria before the deployment expands.

Can all processing stay in our environment?

The architecture supports local processing with locally hosted models. The deployment must keep the required tools and data flows inside that boundary too. Your data never reaches the frontier models.

Are we tied to one model provider?

Caesar is designed to work with interchangeable models. Your knowledge structure, connections and workflow rules stay in the engine when the underlying model changes. Each enabled model is configured and evaluated for the tasks and policies of your deployment.

Is our data used for model training?

HAQQ’s architecture excludes customer data from training HAQQ models. Where an external model is enabled, its processing and retention terms are reviewed separately for the deployment.

Start with one workflow worth improving.

Choose a task your people repeat and a result they know how to judge. We’ll use it to define the data, software and controls the first deployment needs.

Choose the first workflow

Name the users, the records they work from and the output they need. Agree how you will judge whether Caesar improves the work.

Set the operating rules

Define the hosting, permissions, model access and approval steps. Identify which connections and applications need to be configured or built.

Measure before you expand

Test representative work against the agreed criteria. Compare accuracy, reviewer effort, turnaround time and cost before deciding what to expand.
