Questions

How much does a GB300 251 GB rental cost?

From about $17.91 per GPU-hour at the lowest current offer. Prices change with availability, so the live figure above is the one to trust.

How is billing calculated?

Per minute while the server runs, from your balance. The price is fixed at launch. A server that fails to start is not billed.

Do I pay for the GPU when the server is stopped?

No GPU time is billed while the server is stopped. The disk is still billed, so keep only the data you need on it.

Is my data kept?

Data on the disk stays while the server exists. Deleting the server deletes its disk too, so download results first.

Which template should I start with?

Ollama for chatting with language models, ComfyUI or Forge for images and video, PyTorch with Jupyter for training and experiments, Ubuntu with CUDA when you want to install everything yourself.
