Pros & Cons
CoreWeave
Pros
- Free internet egress and internal data transfer, which lowers the cost of moving large datasets and model checkpoints.
- Large inventory of current NVIDIA hardware, from L40S to GB200 NVL72, with InfiniBand for multi-node training.
- Spot rates are well below on-demand rates, for example $19.71 versus $49.24 per hour for an 8-GPU H100 node, and committed discounts reach up to 60%.
- The CKS control plane and SUNK Slurm scheduler are free, so you pay only for compute.
- A Terraform and OpenTofu provider manages clusters, VPCs, storage, and inference as code.
Cons
- No free tier or trial credits, and minimum spend is reported to be high even for light use.
- No managed databases, serverless functions, or CDN, so a second cloud is often needed.
- Regions are concentrated in North America and Europe, with limited Asia-Pacific coverage.
- The best pricing usually requires multi-year contracts and an enterprise sales process.
- Few public user reviews are available on G2 or Gartner to validate claims.
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.
