Radiant was announced recently after Brookfield acquired Ori, a Saudi Aramco backed neocloud with H100s and H200s in London and Dallas. When we tested with Ori on two occasions in the fall, we saw some quick progress but not enough to get to silver. Ori fell victim to the exact same issues as FPT, with PKey and SAKey not configured correctly. In addition, during our first round of testing, we were unable to run nccl-tests at full bandwidth on kubernetes due to an issue with the NetworkOperator picking up NICs that were intended to be for the frontend but were named/configured incorrectly to be used for NCCL. Finally, DCGMI health watches are not enabled by default, and there is no automated background health check program. Our testing of a simple hardware failure simulation showed that the system did not trigger any automated alerting or node replacement over an 18-hour window. The team is targeting Q2 2026 for the release of monitoring dashboards, and seems well on their way to having the funding they need to build Blackwell clusters with comprehensive slurm, kubernetes, monitoring and reliability features customers expect.

Radiant/Ori GPU Cloud FAQ
What tier is Radiant/Ori in ClusterMAX?
Radiant/Ori 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 Radiant/Ori SOC 2 Type II certified?
Radiant/Ori's ClusterMAX review does not flag a SOC 2 Type II attestation as confirmed. SemiAnalysis treats SOC 2 Type II as a baseline expectation for any GPU cloud serving enterprise or regulated AI workloads — see the ClusterMAX criteria page for the full security baseline.
Does Radiant/Ori support Slurm?
Yes. The Radiant/Ori 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 Radiant/Ori support Kubernetes?
Yes. The Radiant/Ori 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 Radiant/Ori offer?
Based on the SemiAnalysis hands-on review, Radiant/Ori offers (or has been publicly tied to) the following NVIDIA / AMD GPU SKUs: H200, H100. Specific inventory, region availability, and on-demand vs reserved access are detailed in the Radiant/Ori ClusterMAX review.
What is the NCCL all-reduce performance on Radiant/Ori?
The Radiant/Ori review on ClusterMAX includes hands-on NCCL all-reduce results from SemiAnalysis testing. NCCL bandwidth (in GB/s) is one of the most important indicators of training cluster health — see the Networking section of the review for the specific numbers and how they compare to the ClusterMAX cohort.
How does Radiant/Ori compare to CoreWeave?
CoreWeave is the only ClusterMAX Platinum provider, while Radiant/Ori is rated Unavailable. The Radiant/Ori review documents the specific gaps versus CoreWeave across the 10 ClusterMAX criteria (Security, Lifecycle, Orchestration, Storage, Networking, Reliability, Monitoring, Pricing, Partnerships, Availability). See the Radiant/Ori review body and the ClusterMAX /criteria page for the full comparison framework.
Is Radiant/Ori recommended for LLM training?
Radiant/Ori's current ClusterMAX rating (Unavailable) means SemiAnalysis does not directly recommend Radiant/Ori for production LLM training without first addressing the specific gaps called out in the review. See the Radiant/Ori review for the gating issues and see the ClusterMAX /cloudreview index for currently recommended alternatives in Platinum / Gold / Silver / Bronze.
