Best Neocloud / GPU cloud providers
GPU cloud providers, compared
Neoclouds, hyperscalers and marketplaces all rent GPUs. Here's which kind fits which job, and how independent ratings rank them.
GPU cloud providers fall into three groups: neoclouds (CoreWeave, Nebius, Lambda, Crusoe), hyperscalers (AWS, Azure, Google Cloud, Oracle) and marketplaces (Vast.ai and similar). The best one depends on how many GPUs you need, for how long, and how fast.
Three kinds of GPU cloud
| Neoclouds | Hyperscalers | Marketplaces | |
|---|---|---|---|
| Examples | CoreWeave, Nebius, Lambda, Crusoe | AWS, Azure, Google Cloud, Oracle | Vast.ai |
| Best at | Dedicated clusters, fast delivery | Bundled services, existing enterprise contracts | Cheap, flexible single GPUs |
| Large clusters | Core business | Available, often via long commitments | Rarely |
| Newest GPUs | Usually first | Close behind | Later, mixed |
| Contract | On-demand to multi-year reserved | Enterprise agreements, commit discounts | Pay as you go |
| Watch for | Financing, capacity still being built | Quota limits, lead times for big blocks | Reliability, one host per GPU |
Best GPU cloud providers by use case
For large training clusters
CoreWeave and Nebius are the two GPU clouds SemiAnalysis rated Platinum in ClusterMAX 3.0 (summary). Lambda and Crusoe also sell GB300 NVL72 and HGX B300. Get quotes from at least three: at this size, who has capacity in your window matters more than the brand. See B300 and GB300 providers.
For a quick start with a few GPUs
Self-service neoclouds such as Lambda, Nebius and RunPod let you launch in minutes with a card. Good for fine-tuning and evaluation.
For inference in production
Reserved nodes from a neocloud, or managed inference from providers such as Together AI. If your app already lives in AWS, Azure or Google Cloud, data transfer and security reviews may favour staying there.
For the lowest cost experiments
A marketplace like Vast.ai. Expect variation between hosts and don't plan multi-node training on it.
How independent ratings compare them
SemiAnalysis ClusterMAX is the most-cited independent rating of GPU clouds. It scores ten areas, from security and networking to reliability and availability. In version 3.0 (September 2026), CoreWeave and Nebius were Platinum, Oracle and Google Cloud Gold, and Lambda, Microsoft Azure, Firmus, TensorWave and GMI Silver, with AWS, Together AI and Crusoe in Bronze (FourWeekMBA summary).

How to compare quotes
Hourly rates rarely tell you which offer is better. Put every quote on the same sheet with: exact system, cluster size on one fabric, region, start date, term, storage and networking included, and total cost over the term. Our six-question checklist gives you the columns.
