What is sovereign AI? Definition, examples and how it differs from ChatGPT Enterprise

Sovereign AI is an artificial intelligence system where you control the three parts that matter: the model doing the reasoning, the data it reads and the infrastructure it runs on. All of it sits under a jurisdiction you picked, not your vendor’s.

The term comes from government policy. On December 5, 2024, the Government of Canada launched the Canadian Sovereign AI Compute Strategy, backed by up to $2 billion, according to Innovation, Science and Economic Development Canada. The logic scales down to a single business: do not depend on a foreign third party for a capability that has become strategic.

In practice, sovereign AI for a Quebec SME runs on a server in its own building or at a hosting provider in its region. The model is an open model the company keeps a copy of. Documents stay inside the boundary the company has drawn. That is the approach Cogio deploys, described on our home page.

The label gets stretched, sometimes to cover nothing more than a data centre located in Canada. Three questions cut through it.

Many businesses think they have solved the problem by picking a vendor that stores data in Canada. That is real progress, but it does not settle jurisdiction.

The American CLOUD Act, passed in March 2018, requires a provider of electronic communication or remote computing services to preserve or disclose data in its possession, custody or control “regardless of whether such communication, record, or other information is located within or outside of the United States.” That is the wording of 18 U.S.C. § 2713.

Microsoft has acknowledged in public that this obligation can reach data hosted outside the United States. Before a French Senate inquiry on June 18, 2025, Anton Carniaux of Microsoft France said he could not guarantee that French citizens’ data would never be passed to US authorities without France’s agreement, while adding that it had never happened, as reported by The Register. He also described Microsoft’s commitments to challenge unfounded requests and to notify the customer where allowed. Those are real safeguards, but they remain contractual. We go deeper in our article on the CLOUD Act and data sovereignty.

ChatGPT Enterprise and similar offerings (Microsoft Copilot, Claude, Gemini) are cloud services. You rent access to a very capable model that an American company hosts and operates. Microsoft, for one, states that prompts, responses and data Copilot reads are not used to train its foundation models. That commitment is serious. It just answers a different question.

The real differences come down to who runs the system, what it knows about your business and what it can do inside your tools.

A manufacturer. At Les Industries Romy in Granby, the agents run on a server in the shop. They read supplier invoices that arrive by email, prepare quotes and write to QuickBooks through its API. No client data leaves the company. The details are in the Romy case study.

A law firm. The Barreau du Québec’s guide on generative AI states that entering information protected by professional secrecy into an open system is a breach, while closed systems reduce those risks. Sovereign AI installed at the firm is that closed system. See our page for law firms and our article on AI and professional secrecy.

A clinic. Health information is among the most sensitive there is. An assistant that summarizes files or drafts correspondence can run on site, without records travelling anywhere. Our healthcare page covers the possible uses, with no clinical act ever handed to the AI.

Law 25 does not forbid American services. Section 17 of Quebec’s Act respecting the protection of personal information in the private sector does require that, before communicating personal information outside Quebec, a business conduct a privacy impact assessment. It must weigh, among other things, the sensitivity of the information, the purpose, the protection measures and the legal framework of the place where it would go. The same rule applies when a third party outside Quebec is entrusted with storing that information.

With sovereign AI hosted in Quebec, the assessment gets much simpler, because nothing is communicated outside Quebec. Our privacy impact assessment guide walks through both cases.

For a small team writing emails and summarizing public material, a subscription does the job well. It is quick to roll out and gives you the newest models. We say so plainly in our honest comparison.

Sovereign AI pulls ahead in three situations. First, when the data is regulated or covered by professional secrecy. Second, when the AI has to act inside your systems, such as posting to your ERP or filing your email, which takes deep access you would rather keep in house. Third, when headcount pushes the monthly bill up. If you run Business Central or Acumatica, our agents connect directly: see Business Central AI integration and Acumatica AI integration.

There is a middle road. Everyday tasks go to the subscription and sensitive documents go to sovereign AI. What matters is deciding in advance which data goes where and writing it down in an AI acceptable use policy.
