Training a model in the same league as Grok 3 requires a dedicated AI factory: thousands of accelerators, megawatts of firmed power, low-PUE cooling, sovereign data residency and a multi-year financing structure. Below is how we translate the public profile above into a deployable plan.
We size GPU/TPU equivalents to your target FLOPs, accounting for MFU (Model FLOPs Utilization), checkpointing overhead and fault tolerance.
From the 150 MW (Colossus, on-site gas turbines) reference, we derive substation requirements, PUE targets and cooling architecture (DLC, immersion, hybrid).
Full 20-year financial model: hardware, real estate, energy contracts, staffing, refresh cycles. Stress-tested against energy price scenarios.
EU residency, NIS2 / GDPR alignment, optional air-gapped operation. No US CLOUD Act exposure.
Talk to our infrastructure team. We size GPU clusters, power, cooling and financing for frontier-scale training and inference workloads — on sovereign EU infrastructure.
Public estimates for Grok 3 indicate the cluster scale, capex and energy footprint required to train a peer model. We translate that into a deployable plan on EU-sovereign infrastructure.
