Meta Grand Teton

Meta designed its own GPU server platform and open-sourced the design through the Open Compute Project rather than buying one from an integrator, which puts the rack itself in the same category as Graviton, Trainium and EFA: infrastructure a hyperscaler builds because it is cheaper than paying someone else's margin at its scale, and infrastructure invisible to any market analysis that counts units a vendor shipped. Grand Teton is what the Meta GenAI clusters on this site are built from, and open-sourcing it does not make it purchasable; it makes the design public while the manufacturing still runs through Meta's own supply chain.
