💡 Our Take
Choose Nebius if you need EU-based compute capacity, deep managed-service integration (MLflow, PostgreSQL, Spark) and included solution-architect support for multi-node jobs. Choose CoreWeave if you want the largest North American GPU footprint, earlier access to certain SKUs at hyperscale, and tight integrations already used by major model labs in the US.
CoreWeave - Pros & Cons
Pros
- ✓Purpose-built GPU infrastructure delivers up to 35x better price-performance than hyperscalers for AI training workloads due to optimized networking and scheduling
- ✓GPU availability is significantly better than AWS or Azure — CoreWeave provisions H100 clusters in minutes rather than weeks-long waitlists
- ✓Kubernetes-native architecture lets ML engineering teams use familiar tools (kubectl, Helm) without learning proprietary orchestration systems
- ✓InfiniBand networking between GPU nodes enables near-linear scaling for multi-node distributed training jobs
- ✓Operates 32+ data centers with tens of thousands of NVIDIA GPUs, providing substantial capacity for large training runs
- ✓Flexible commitment options from on-demand hourly billing to 1-3 year reserved contracts with significant discounts
Cons
- ✗No free tier or trial credits available — minimum spend starts at several hundred dollars per month even for light usage
- ✗Limited non-GPU services: no managed databases, serverless functions, or CDN, so teams typically need a second cloud provider
- ✗Geographic coverage is narrower than hyperscalers — primarily US and select European locations, with limited Asia-Pacific presence
- ✗Smaller ecosystem of tutorials, community forums, and third-party integrations compared to AWS, Azure, or GCP
- ✗Enterprise sales process can be lengthy for large reserved capacity commitments, with multi-year contracts often required for best pricing
Nebius AI Cloud - Pros & Cons
Pros
- ✓Reference Platform NVIDIA Cloud Partner status — a tier reserved for select partners operating large clusters built in coordination with NVIDIA's tested reference architecture
- ✓Access to cutting-edge NVIDIA GPUs including GB300 NVL72 and GB200 NVL72 in addition to H100 and H200
- ✓Verified customer cost savings — CentML reported 5x lower inference costs compared to other major providers
- ✓EU-based compute capacity (data center outside Helsinki) supports data-residency and regulatory compliance requirements
- ✓24/7 solution architect assistance for multi-node cases is included at no additional charge
- ✓Operates ISEG, the #19 most powerful supercomputer in the world, giving credible evidence of large-cluster capability
Cons
- ✗Pricing is not fully transparent on the homepage — custom quotes require contacting sales for enterprise configurations
- ✗Smaller global footprint than AWS, GCP, or Azure — limited regional options outside Europe may affect latency-sensitive workloads
- ✗Focused specifically on AI/ML compute rather than being a general-purpose cloud (no broad PaaS, serverless, or consumer-web services)
- ✗Advanced features like InfiniBand clusters and managed Slurm target experienced ML engineers rather than beginners
- ✗Smaller third-party ecosystem and marketplace compared to hyperscaler competitors
