The only AI cloud with a Platinum rating — see why CoreWeave leads.
SemiAnalysis created ClusterMAX™, the world’s first independent AI cloud rating system. Designed from the perspective of the average enterprise customer, it evaluates dozens of GPU clouds and ranks them across five tiers: Platinum, Gold, Silver, Bronze, and UnderPerform.
Through year-long tests scaling from a single node to 1,000+ GPU clusters, the SemiAnalysis team benchmarked the features that matter most to AI Innovators.
