Why rent instead of buy
A GPU that costs thousands to buy can be rented for well under a dollar an hour. When renting makes sense and when buying does.
Three ways to rent
- A GPU virtual machine (pod): full control, billed per hour or second.
- A marketplace GPU: cheaper, from independent hosts.
- Serverless GPU: pay only while your code runs.
Pick the right GPU

Your first rented GPU, step by step
Create an account, choose a template (Ollama, ComfyUI or Jupyter), connect, run a model, and stop the instance so billing stops.
Avoid surprise bills
Stop vs terminate, storage charges, auto-shutdown, spending limits.
What it costs
Worked examples: one evening of image generation, a week-long fine-tune, an always-on chatbot.
