B300 spot questions
What is a spot B300 node?
An idle 8×NVIDIA B300 node that you rent until we need it back. You get the whole node, not a share of one. When we take it back, you get at least the notice you asked for.
How much does a spot B300 cost?
You name the most you'll pay per GPU-hour, and we only offer you nodes at or below that price. A node has 8 GPUs, so $6/GPU-hr comes to $48 per node-hour.
Can I rent a single B300 GPU?
No. Spot capacity comes only as whole 8×B300 nodes. You can ask for one node, two, three to four, or five or more.
How much notice do I get before a node is taken back?
You choose the minimum when you sign up: none (best effort), 1 hour, 12 hours, or 24 hours or more.
What can I run on spot B300s?
Work that can stop and resume: RL rollouts, evals, batch inference, and training or fine-tuning that checkpoints often.
How do I get a spot B300 node?
Fill in the form on this page. We'll email you when a node frees up that fits your price and notice.
