Fireworks expands European capacity with NVIDIA Vera Rubin and Grace Blackwell platforms - VMblog

Fireworks' European capacity lock-in around Vera Rubin and Grace Blackwell is less a compute expansion and more a regulatory arbitrage against the EU AI Act's data-residency mandates. Vera Rubin's projected 1,200W-plus per-GPU thermal envelope collides head-on with Europe's three-to-five-year grid expansion cycle — whoever secures power and liquid-cooling infrastructure first captures pricing power over inference workloads through 2027. Upstream, HBM4 delivery cadence and 1.6T optical interconnect lead times will gate the actual cluster go-live window, not the chip's announcement date. Downstream, Grace Blackwell's unified memory architecture is rewriting the inference serving stack: multi-modal, long-context workloads demand sub-millisecond local latency, rendering cross-Atlantic calls economically unviable. Competitively, CoreWeave and Together AI remain US-centric in their European footprint, while OVHcloud's in-house silicon roadmap lags the NVIDIA ecosystem's maturity and software-stack depth. Within 12 to 24 months, European AI infrastructure will bifurcate into a sovereign tier and a commercial tier, with GPU allocation quotas — not raw FLOPS — becoming the binding constraint on the entire region's AI throughput.
