SemiAnalysis rates Nebius Platinum in ClusterMAX 3.0 AI cloud ranking

SemiAnalysis placed Nebius in its Platinum tier, its highest, in the ClusterMAX 3.0 ranking of AI cloud providers. The evaluation ran training and inference workloads for several months on live NVIDIA GB300 and HGX B300 clusters and tested burn-in, storage under concurrent load and node and rack recovery. Nebius's own write-up quotes SemiAnalysis calling it an industry leader, though the findings also list storage issues that Nebius later fixed.
