We are proud that CoreWeave, the AI Hyperscaler™, was the only AI cloud provider to receive the highest Platinum rating based on SemiAnalysis’s ClusterMAX™ Rating System . ClusterMAX™ evaluated dozens of providers including AWS, GCP, Azure, Crusoe, Nebius, and Lambda, and rated them from the perspective of an average reasonable customer. The ClusterMAX™ Platinum rating represents providers that are raising the industry bar and according to SemiAnalysis, there is only one AI cloud, CoreWeave, that provides services at the Platinum tier. SemiAnalysis also recognized that CoreWeave’s cloud platform, purpose-built for AI, demonstrated industry leadership in operating large-scale 10k+ H100 clusters reliably. CoreWeave’s unmatched performance and scalability are why leading AI labs including OpenAI, Mistral, Cohere and enterprises including IBM and JaneStreet choose CoreWeave for their AI workloads. The CoreWeave Cloud Platform is purpose-built—from metal to model—to deliver maximum performance and efficiency for AI workloads. We’ve led the way with a series of industry firsts—from early access to NVIDIA GB200 , H100 and H200 GPUs, to achieving record-breaking AI inference performance with MLPerf 5.0 benchmarks using NVIDIA Grace Blackwell Superchips. Performance optimizations are integrated across every layer—from infrastructure to managed Kubernetes and application services such as CoreWeave Kubernetes Service and Slurm on Kubernetes (SUNK) —delivering 20% Higher GPU Cluster Performance than alternative solutions. Our Mission Control platform enables rapid deployment of the latest hardware, and our focus on reliability means 50% fewer interruptions and higher system goodput (96% vs. 90% industry average). With CoreWeave, customers get industry leading reliability, scale, and infrastructure efficiency for AI workloads — and everything is included in the price, with no hidden fees or surprise support costs. “ CoreWeave’s product offerings set a new standard across the GPU cloud industry. Their industry-leading cluster burn-in and automated node lifecycle controller proactively run both passive and active health checks to catch unhealthy nodes and identifies issues such as Link flaps, convergence issues, silent data corruptions (SDC), etc. As demand for high-performance compute continues to grow, CoreWeave’s investments in software and hardware infrastructure makes them a clear leader in GPU cloud reliability." — Dylan Patel, Chief Analyst, SemiAnalysis In this blog, we summarize the methodology and findings from the report, and also go deeper into how we build and operate CoreWeave Cloud Platform to deliver industry leading performance and reliability. ClusterMAX™ rating system by SemiAnalysis - Methodology Over the last 12 months, SemiAnalysis independently tested and/or collected customer feedback from dozens of cloud providers they view as ready for customers for AI workloads and created the GPU Cloud ClusterMAX™ Rating System, or ClusterMAX™ for short. SemiAnalysis performed extensive benchmarking and profiling to represent customer needs. They also attempted to scale workloads from single nodes to thousands of GPUs to arrive at their results and evaluated providers across multiple dimensions including security, performance, reliability, technical expertise, operational posture etc. Upon completion of their assessment, SemiAnalysis rated cloud providers across 5 tiers (from highest to lowest): Platinum, Gold, Silver, Bronze, and UnderPerform. CoreWeave’s rating of ClusterMAX™ Platinum tier represents the highest rating in the industry, and currently CoreWeave is the only AI cloud that is “raising the industry bar and qualifies for ClusterMAX™ Platinum ”, according to SemiAnalysis. “ Providers in this category consistently excel across evaluation criteria, including security, price for value, technical expertise, reliability backed by clearly defined SLAs, seamless managed Slurm/Kubernetes offering, and best in class NCCL/RCCL networking performance. Platinum-tier providers are proactive, innovative, and maintain an active feedback loop with the community to continually raise the bar. ” SemiAnalysis concluded in their report that “ CoreWeave is clearly leading in providing the best GPU cloud experience and has very high goodput and are entrusted to manage the large-scale GPU infrastructure for AGI labs like OpenAI, high frequency trading firms like Jane Street, and even NVIDIA’s internal clusters. ‍ ” The ClusterMAX™ Rating System and content within the SemiAnalysis report were prepared independently by SemiAnalysis. No part of SemiAnalysis’s compensation by SemiAnalysis's clients was, is, or will be directly or indirectly related to the specific tiering, ratings or comments expressed in SemiAnalysis's article.
