Pros & Cons
Fluidstack
Pros
- Can build and deliver capacity at gigawatt scale, which is why Anthropic chose it for its Texas and New York data centers.
- Runs managed Slurm and Kubernetes on bare metal, so training teams do not have to operate the cluster themselves.
- SemiAnalysis gave its GPU clusters a ClusterMAX Gold rating.
- Heavily funded, including an $830M Series A in January 2026, which lowers the risk that the supplier fails.
Cons
- There is no public rate card or self-serve signup, so pricing requires a sales quote.
- Public documentation on APIs, storage and compliance certifications is scarce.
- Third-party sources say its GPU catalog is narrower than marketplace providers and that on-demand billing is per hour.
- It offers no general web hosting, managed databases or app platform services.
Nebius
Pros
- Newest NVIDIA hardware, including B300 and GB300 NVL72, is listed with published per-hour prices.
- Network egress, ingress and public IPs are free, which removes a common hidden cost on hyperscalers.
- The certification list is broad: SOC 2 Type II, SOC 3, several ISO standards including 27001 and 42001, and CSA STAR.
- EU data centers in Finland and Paris help with GDPR and data residency.
- Infrastructure as code is fully supported through a CLI, a Terraform provider, gRPC and REST APIs, and SDKs.
Cons
- The catalogue is narrow outside AI. The only managed database is PostgreSQL, and there is no CDN or web hosting.
- Some users report slower support responses than AWS or CoreWeave.
- Users note documentation gaps for advanced setups.
- Kubernetes and Slurm workflows assume DevOps expertise.
- Commitment pricing and the largest clusters require contacting sales.
