OpenAI Teams with Chipmakers on MRC Protocol

OpenAI announced partnership with AMD, Broadcom, Intel, Microsoft, and Nvidia to launch Multipath Reliable Connection (MRC) protocol.
MRC extends RDMA over Converged Ethernet, splits interfaces into hundreds of parallel links, enabling microsecond‑scale failure routing.
Protocol deployed on OpenAI’s Nvidia GB200 supercomputers at Oracle Cloud in Texas and Microsoft’s Fairwater systems.
OpenAI reports over 900 million weekly ChatGPT users; rebooted four tier‑1 switches during recent model training without coordination.
