OpenAI Introduces MRC for Large-Scale AI Training Networks

Unlocking large scale AI training networks with MRC (Multipath Reliable Connection)

OpenAI introduced MRC for large-scale AI training cluster networks. MRC stands for Multipath Reliable Connection and is released via OCP to improve resilience and performance; the post does not disclose throughput, latency, or cluster size.

Why it matters: HKR-H/K/R pass: OpenAI shared MRC via OCP, with a concrete multipath reliability mechanism. No throughput, latency, or cluster scale is disclosed, so this stays in the 72–77 featured band.
