Frequently asked questions
How much does it cost to rent a B300 SXM6 on Lium?
B300 SXM6 pods are listed at $8.00 to $10.00 per GPU-hour right now, across 8 pods with 58 GPUs. Each provider sets its own price and the range moves as pods are added and removed.
Where is the cheapest place to rent a B300 SXM6 by the hour?
On Lium, B300 SXM6 pods start at $8.00 per GPU-hour right now, the lowest live ask across 8 pods, and billing is per second with no minimum, so a 20-minute job costs a third of that. Providers set their own prices, so the lowest ask moves as pods are listed and rented.
Is there a minimum rental period?
No. Lium bills per second with no minimum and no reservation: start the pod when you need it, delete it when the job is done, and pay for the seconds it ran.
How do I rent a B300 SXM6 pod?
Top up a balance by card or crypto, pick a B300 SXM6 pod on the marketplace, choose a Docker template, add your SSH key and deploy. From a script, run lium up with the node id after exporting LIUM_API_KEY.
Where do the machines run, and what happens to my data?
Providers run their own hardware in their own facilities, and every pod on the marketplace names its city and country, so you can pick a region before you start. Your data lives on the machine you rented and is released when you delete the pod; attach a volume if you need storage that outlives a single pod.
