How much does it cost to rent a GB300?

Owners set their own price per GPU-hour, which depends on the number of servers, the term and the start date. Send a request with what you need and we come back with offers.

What is the minimum term for reserved GB300 capacity?

Usually one month or more, set by each owner. Longer terms usually get a lower price per GPU-hour.

How much memory does a GB300 have?

288 GB HBM3e per GPU (NVIDIA Blackwell Ultra).

Can I rent a single GB300 server?

Yes, where the owner allows it: each listing shows how many servers it has and you can ask for one or for all of them.

NVIDIA Blackwell Ultra

Rent GB300 servers, reserved from data centers

GB300 pairs a Grace CPU with two Blackwell Ultra GPUs, and is mostly sold as the GB300 NVL72 rack: 72 GPUs in one NVLink domain that behaves like a single very large accelerator. It is aimed at training and serving the largest models, where the rack-scale NVLink matters more than the per-GPU price.

Memory per GPU: 288 GB HBM3e
Architecture: Blackwell Ultra

What GB300 is good for

Training frontier-scale models across one NVLink domain
Serving very large mixture-of-experts models with long context
Reasoning workloads that need many GPUs answering one request

What to ask before you reserve GB300 capacity

Whether you get a whole NVL72 rack or a slice of one, and how many racks share the network.
The liquid-cooling and power arrangement, and who is responsible when a tray fails.
How the servers are interconnected (InfiniBand or RoCE, and at what speed per GPU) if you will train across nodes.
Whether the price covers storage, egress and support, or only the GPU-hours.
The uptime they commit to, and what you get back when they miss it.
