A sourced model and short report on a single question:
Can Europe stand up a sovereign frontier-class AI model now, by federating the public compute it already owns, while the gigawatt datacenters it is planning take years to connect to the grid?
The answer the model gives is yes, as a stopgap. Europe already operates tens of exaflops of public AI compute across the EuroHPC supercomputers and the national AI Factories. A 1 GW campus, by contrast, waits a mean of 7.6 years for grid power. Federated with low-communication (DiLoCo-style) training, the compute Europe already has can deliver a frontier-class model around 2028, against around 2033 for a new gigawatt campus.

The model in one paragraph
Three layers. Layer 1 is the per-FLOP efficiency of low-communication training (how much the DiLoCo penalty costs). Layer 2 is time-to-availability (when sites energize and how fast cumulative compute accrues). Layer 3 is a per-region scorecard on time, cost, carbon, and feasibility. The headline result is set almost entirely by Layer 2: it reduces to one inequality, the federation wins if its sites are online before a gigawatt campus is. The training efficiency penalty is second-order, confirmed by the sensitivity tornado.
