## Questions

**How much does it cost to rent a B300?** As of 13 Oct 2026, 17:57 UTC, the lowest price for an NVIDIA B300 on Arrakis is $8.00 per GPU-hour, with 14 GPUs available on 2 machines. You pay the hourly price shown when you rent, from a prepaid balance. A machine bills from start to removal, and a started hour counts as a full hour.

**Can an AI agent rent the B300 on Arrakis?** Yes. Give the agent a spend-capped token and connect it over MCP or the REST API. It can search for a B300, rent it for a set number of hours, and shut it down, and it cannot spend past its cap.

**Which B300 configurations can I rent?** It depends on live supply. Each listing shows the exact model, memory, GPU count, CPU and RAM, country and region, and a reliability score, so you can choose the machine that fits.

**Do I get root access?** Yes. You SSH in as root and can run any Docker image, with your own SSH keys and optional volumes for data.
