Meta used the 2026 OCP Global Summit to share networking innovations supporting its latest AI models (including Muse Wonder and Muse Spark) and its gigawatt-scale Prometheus cluster. The shipped and previewed work spans liquid-cooled switch racks, a flattened scale-out fabric, petabit-scale scale-across, Ethernet scale-up for MTIA, a new switch platform standard, and an open-sourced RDMA transport.
