Want to model Corvex cluster cost? Calculate H100, H200, B200 & GB200 NVL72 TCO with the ClusterMAX calculator.

Corvex (formerly Klustr) currently operates H200 and B200, with expansion plans for GB200 NVL72 systems coming soon. During our testing period, Corvex was unfortunately sold out.

We appreciate that in order to serve their customers, notably secure federal government agencies in the US, Corvex maintains strict compliance with SOC 2 Type II, ISO 27001/27017/27018, PCI-DSS, and FedRAMP certifications, along with InfiniBand and RoCEv2 isolation, SR-IOV safety controls, and automatic customer notification and CVE patch management. The platform advertises automated Slurm and Kubernetes provisioning, out-of-the-box topology configuration, and integrated Grafana monitoring tied into DCGM and job telemetry.

We look forward to testing Corvex in the future.

Corvex GPU Cloud FAQ

What tier is Corvex in ClusterMAX?

Corvex is rated Unavailable tier in the ClusterMAX 2.0 GPU cloud rating system by SemiAnalysis (with the ClusterMAX 2.1 Update applied April 2026). Unavailable is tracked by ClusterMAX but not yet directly verifiable for hands-on testing. Interesting service we cannot verify yet (not launched, sold out, government-only, etc.).

Is Corvex SOC 2 Type II certified?

Corvex's review on ClusterMAX explicitly discusses SOC 2 posture. See the Security section of the Corvex review for the current SOC 2 status, scope of the report, and any related attestations (ISO 27001, HIPAA) tracked by SemiAnalysis.

Does Corvex support Slurm?

Yes. The Corvex review on ClusterMAX covers their Slurm offering — including whether it is managed, self-managed, or runs as Slurm-on-Kubernetes (SUNK, Soperator, or Slinky). See the Orchestration section of the review for the specific Slurm flavor offered and SemiAnalysis' hands-on experience.

Does Corvex support Kubernetes?

Yes. The Corvex review on ClusterMAX covers their Kubernetes offering — whether managed Kubernetes is provided, what control plane is used, and how GPU operator, networking, and storage integrate. See the Orchestration and Storage sections of the review for details.

What GPUs does Corvex offer?

Based on the SemiAnalysis hands-on review, Corvex offers (or has been publicly tied to) the following NVIDIA / AMD GPU SKUs: GB200 NVL72, GB200, B200, H200. Specific inventory, region availability, and on-demand vs reserved access are detailed in the Corvex ClusterMAX review.

What is the NCCL all-reduce performance on Corvex?

Corvex's ClusterMAX review does not yet publish hands-on NCCL all-reduce results. NCCL all-reduce bandwidth is the standard SemiAnalysis benchmark for InfiniBand / RoCE health on GPU clusters — see the ClusterMAX /health-checks page for the full benchmark methodology.

How does Corvex compare to CoreWeave?

CoreWeave is the only ClusterMAX Platinum provider, while Corvex is rated Unavailable. The Corvex review documents the specific gaps versus CoreWeave across the 10 ClusterMAX criteria (Security, Lifecycle, Orchestration, Storage, Networking, Reliability, Monitoring, Pricing, Partnerships, Availability). See the Corvex review body and the ClusterMAX /criteria page for the full comparison framework.

Is Corvex recommended for LLM training?

Corvex's current ClusterMAX rating (Unavailable) means SemiAnalysis does not directly recommend Corvex for production LLM training without first addressing the specific gaps called out in the review. See the Corvex review for the gating issues and see the ClusterMAX /cloudreview index for currently recommended alternatives in Platinum / Gold / Silver / Bronze.
