If you are comparing GPU cloud providers, the first thing to know is that they are not all selling the same product. This guide sorts the main options by how they work, then gives a checklist for comparing them fairly. For current hourly rates, use the ComputeClarity calculator, which shows the stored rate for each provider and the date it was collected.

The four kinds of provider

Marketplaces let independent hosts list their machines, so price and reliability vary by listing. Managed GPU clouds run their own infrastructure and sell it with a more consistent experience. API platforms host AI models for you and charge for usage, so you do not rent a GPU at all. Hyperscalers sell GPUs alongside a wide range of other services.

Marketplaces

Vast.ai is a marketplace where independent hosts list GPUs, including verified datacentre hosts. That gives a wide range of prices and quality, so check a host's details before you rely on it. See our comparison of Vast.ai and RunPod.

Managed GPU clouds

RunPod offers managed GPU instances and serverless options. Our guides cover RunPod alternatives and Vast.ai alternatives.

Lambda Labs and Nebius run their own GPU clouds and publish price lists. See Lambda GPU pricing explained for what Lambda lists today. Our Nebius vs Lambda Labs comparison goes through GPUs, regions, egress and security credentials from their own pages, and the Lambda Labs alternatives guide covers what to consider if capacity is tight.

API platforms

Novita gives access to hosted AI models through an API, so you pay for usage instead of renting a GPU. That suits you if you want to call existing models and not run your own. See Vast.ai vs RunPod vs Novita.

Hyperscalers

AWS, Azure and Google Cloud sell GPU machines inside a much wider platform. They can make sense if your data and services already live there or you have credits. See AWS vs specialist GPU cloud, Azure GPU pricing alternatives and GCP GPU pricing alternatives.

A checklist for comparing fairly

Compare the same GPU model and memory size on each provider. Compare on demand with on demand, in the same currency, and divide multi-GPU server prices by the number of GPUs. Check egress and storage terms, because they differ. Check regions against where your data and users are. Check how a short job is billed. Look at the security information each provider publishes if you handle sensitive data. And check the date on every price.

Where to start

If you are experimenting, a marketplace or a managed GPU cloud with on demand billing keeps your commitment low. If you only need to call models, an API platform may cost less than renting a GPU. Whatever you pick, run a short test first, and keep a second provider as a fallback. For the costs that sit outside the hourly rate, read the 5 hidden costs in every GPU cloud quote.
