Ask five organisations what "sovereign AI" means, and you'll get five different answers. The catch is all of them are right. Every enterprise racing to adopt AI eventually hits the same walls: where does the model run, where does the data go, and who can see it. For banks, telcos, defence organisations, or critical national infrastructure operators, sending data to a foreign-managed server is usually legally prohibited. Regulation, procurement rules, and national security requirements are rewriting the AI buying decision before a single GPU gets provisioned. That's the sovereign AI problem: delivering frontier-capable AI to organisations whose sensitive code, data, and operational context must stay inside controlled infrastructure. Join CoreWeave and Cosine to unpack what sovereign AI requires, and how the two are working together to give EMEA organisations a credible, homegrown path to frontier-class AI.
In this webinar, we'll cover and demonstrate:
What “sovereign” means for you. Sovereignty isn’t a series of checkboxes. A bank’s definition might center on data residency, a defence organisation’s on air-gapped deployment, a telco’s on model provenance and supply chain. We’ll map the spectrum and show why the real question isn’t “is this sovereign?” but “does this meet our definition of sovereign, and can we prove it?”
Why the UK is moving faster than any other region on this. National AI programs, defence and financial-services regulation, and a hard deadline on reducing dependence on non-European infrastructure.
Cosine’s own model, Lumen Sovereign. Built to be sovereign and secure from the start, for organisations that can’t send code or data outside their own walls.
How CoreWeave’s European data centers and dedicated capacity give models like Lumen a home that’s fast, auditable, and under the customer’s control from day one.
Live demo: governance that proves itself, not just claims it. Karan will walk through the Responsible AI Toolkit, showing how it bridges policy to evidence: encoding an organisation’s compliance rules as versioned policy checks, running red-team probes and framework-coverage mapping (NIST AI RMF, EU AI Act), and tracing every step through W&B Weave so a reviewer gets a reproducible, evidence-backed approval record rather than a self-attestation form. This is the practical answer to “how do we prove sovereignty and governance, not just claim it.”
What a real deployment looks like for a regulated enterprise. Tying it together: sovereign infrastructure (CoreWeave) + a sovereign model (Lumen) + an auditable governance layer (the toolkit + Weave) as one deployable stack.
Sovereign AI isn’t a smaller version of the AI everyone else gets. Done right, it’s the same frontier capability, built on ground you own, along with the receipts to prove it.
Who should attend
