OpenAI released MRC (Multipath Reliable Connection), an open networking protocol developed in collaboration with AMD, Broadcom, Intel, Microsoft, and NVIDIA to address bottlenecks in large-scale AI supercomputer training clusters. The protocol, announced May 6, aims to improve data transfer efficiency across distributed AI training infrastructure beyond traditional Ethernet capabilities. The specification represents a joint industry effort to standardize networking solutions as AI model training scales to increasingly massive computational requirements.
