Aethir functions as an underlying infrastructure partner by creating a decentralized GPU compute infrastructure (DePIN). It aggregates globally distributed, idle GPU capacity and rents it out for both AI and cloud gaming. Its model is built on its own cryptocurrency token (ATH), which is used by investors to “stake” GPUs and provide liquidity, effectively trading on the volatility of spot instance pricing.

Unfortunately, Aethir is not truly a self service experience, requiring prospective buyers to fill out a form in order to purchase GPU time on their platform.

It seems that this decentralized network concept, while particularly useful for cloud gaming, has not taken off yet for AI. Aethir does not have any security compliance attestation in place for users to assess if the company taking payments and managing the GPU access has access controls in place.

Aethir GPU Cloud FAQ

What tier is Aethir in ClusterMAX?

Aethir is rated Underperforming tier in the ClusterMAX 2.0 GPU cloud rating system by SemiAnalysis (with the ClusterMAX 2.1 Update applied April 2026). Underperforming is flagged by ClusterMAX as underperforming — capable of reaching Bronze or Silver if critical gaps are fixed. Can rise to Bronze or Silver quickly if critical issues are fixed (security attestation, modern GPUs, etc.).

Is Aethir SOC 2 Type II certified?

Aethir'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 Aethir support Slurm?

Aethir's ClusterMAX review does not call out a first-party managed Slurm offering. Customers wanting Slurm-on-Kubernetes (SUNK, Soperator, Slinky) should compare Aethir against providers that explicitly list managed Slurm in their offering — see the ClusterMAX /slurm expectations page for the full bar.

Does Aethir support Kubernetes?

Aethir'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 Aethir offer?

The Aethir 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 Aethir?

Aethir'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 Aethir compare to CoreWeave?

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

Is Aethir recommended for LLM training?

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