A group's deep learning infrastructure acts as a multiplier on research progress, determining how effectively teams can conduct experiments and develop models. Open-source tools and frameworks are now mature enough that researchers without specialized resources can build competitive infrastructure setups. This democratization of tools means infrastructure quality no longer primarily depends on institutional funding or proprietary systems.

The infrastructure layer of AI is consolidating around a new constraint: not chips, but the wires connecting them. Lumilens emerged from stealth with a $5.51 billion valuation and $700 million in Series C funding after securing multi-billion-dollar commitments from hyperscalers, a striking validation that optical interconnects—not GPUs—are now the bottleneck in building trillion-parameter clusters. Meanwhile, Nscale is preparing a US IPO on the back of a $51 billion contract backlog and quarterly revenue that jumped from $37 million to over $100 million in six months, betting that vertical integration across power, data centres, GPUs, and software will command a premium from public markets. Both companies are surfing the same wave: the shift from GPU scarcity to connectivity scarcity, and the realization that hyperscalers prefer owning infrastructure end-to-end rather than renting from cloud providers.
