SAKURA GPU Cloud FAQ
What tier is SAKURA in ClusterMAX?
SAKURA 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 SAKURA SOC 2 Type II certified?
SAKURA'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 SAKURA support Slurm?
SAKURA's ClusterMAX review does not call out a first-party managed Slurm offering. Customers wanting Slurm-on-Kubernetes (SUNK, Soperator, Slinky) should compare SAKURA against providers that explicitly list managed Slurm in their offering — see the ClusterMAX /slurm expectations page for the full bar.
Does SAKURA support Kubernetes?
SAKURA's ClusterMAX review does not document a first-party managed Kubernetes service. See the ClusterMAX /k8s expectations page for the managed-Kubernetes bar SemiAnalysis tests against when evaluating GPU cloud providers.
What GPUs does SAKURA offer?
The SAKURA ClusterMAX review covers their current GPU inventory and on-demand availability. SemiAnalysis tracks H100, H200, B200, GB200 NVL72, GB300 NVL72, and MI300X / MI355X availability across all 85 providers in the ClusterMAX 2.0 + 2.1 cohort.
What is the NCCL all-reduce performance on SAKURA?
SAKURA'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 SAKURA compare to CoreWeave?
CoreWeave is the only ClusterMAX Platinum provider, while SAKURA is rated Unavailable. The SAKURA review documents the specific gaps versus CoreWeave across the 10 ClusterMAX criteria (Security, Lifecycle, Orchestration, Storage, Networking, Reliability, Monitoring, Pricing, Partnerships, Availability). See the SAKURA review body and the ClusterMAX /criteria page for the full comparison framework.
Is SAKURA recommended for LLM training?
SAKURA's current ClusterMAX rating (Unavailable) means SemiAnalysis does not directly recommend SAKURA for production LLM training without first addressing the specific gaps called out in the review. See the SAKURA review for the gating issues and see the ClusterMAX /cloudreview index for currently recommended alternatives in Platinum / Gold / Silver / Bronze.
