Node Types

Important

Due to high demand, A100 NVLINK (HGX) and H100 NVLINK (HGX) nodes are currently fully committed on client contracts, and are therefore not available for on-demand use. We recommend a conversation with the CoreWeave team to build a strategic plan catered to your needs to make use of available infrastructure and to plan for your future capacity requirements. Contact CoreWeave Sales to get started.

CoreWeave offers a "Standard Instance," which is useful for most workloads per GPU type offered on CoreWeave Cloud. These instances are a starting point, but can be configured entirely to suit your use case or compute needs.

You can view Standard Instance configurations on our website's pricing page.

For more information about à la carte pricing of compute components on CoreWeave Cloud, see Resource Based Pricing.

Component availability

The following table outlines the physical limitation of how many GPUs are available per instance when customizing your instances on CoreWeave Cloud.

A100 PCIe	Ampere	80 GB	8	A100_PCIE_80GB
A40	Ampere	48 GB	8	A40

RTX A5000	Ampere	24 GB	8	RTX_A5000
RTX A4000	Ampere	16 GB	7	RTX_A4000
Tesla V100 NVLINK	Volta	16 GB	8	Tesla_V100_NVLINK
RTX 5000	Turing	16 GB	4	Quadro_RTX_5000
RTX 4000	Turing	8 GB	7	Quadro_RTX_4000

Important

If a workload requests more peripheral compute resources (vCPU, RAM) than offered in a standard instance size, additional costs will incur.

CPU availability

CPU-only nodes are best suited for tasks such as control-plane services, databases, ingresses and CPU rendering.

CPU Model	Max RAM per vCPU	Max vCPU per Workload	Label
Intel Xeon v3	4 GB	70	intel-xeon-v3
Intel Xeon v4	4 GB	60	intel-xeon-v4
Intel Xeon Ice Lake	4 GB	94	intel-xeon-icelake
Intel Xeon Scalable	6 GB	94	intel-xeon-scalable
AMD Epyc Milan	4 GB	46	amd-epyc-milan
AMD Epyc Rome	4 GB	46	amd-epyc-rome

Note

Workloads without GPU requests are always scheduled on CPU nodes.

Requesting compute in Kubernetes

A combination of resource requests and node affinity is used to select the type and amount of compute for your workload. CoreWeave Cloud relies only on these native Kubernetes methods for resource allocation, allowing maximum flexibility. The label used to select the GPU type is gpu.nvidia.com/class. CPU type is selected using the label node.coreweave.cloud/cpu.

Note

These labels are mutually exclusive - a specific CPU type cannot be explicitly selected for GPU nodes.

Note

Kubernetes allows resources to be scheduled with requests and limits. When only limits are specified, the requests are set to the same amount as the limit.
