According to @ai_darpa on Twitter, NVIDIA CEO Jensen Huang has announced that the Vera Rubin AI platform is now in full production, outpacing the availability of Blackwell GPUs with sufficient RAM. The Vera Rubin platform delivers significant advancements for AI infrastructure, including up to 10x lower inference token costs and requiring 4x fewer GPUs for mixture-of-experts (MoE) model training compared to Blackwell. Additional improvements cited include 5x better energy efficiency and 5x longer uptime through Spectrum-X Photonics, as well as 10x higher reliability via Ethernet Photonics. Assembly and maintenance times are also improved by up to 18x. These enhancements present substantial cost savings and operational efficiency for enterprises deploying large-scale AI clusters, underscoring NVIDIA's aggressive hardware update cycle and its impact on AI infrastructure investment strategies (source: @ai_darpa, Twitter, Jan 6, 2026).
