Cost = current lowest hourly rate × duration. This is an estimate of compute rental only — storage, bandwidth and image fees are excluded, and spot prices change at any time. For long runs, compare monthly plans.

How to choose

Start on the cheapest spot / idle instances — a few yuan is enough to run the whole pipeline once
T4 16GB is perfectly adequate for small models and teaching demos, and stays cheap year-round
Always shut down when done — the most common source of overspend on student accounts is forgetting to stop the instance

FAQ

What's the cheapest way for a student to rent a GPU?

Spot / idle instances often cost under ¥1 per hour (e.g. RTX 3090, T4). This page sorts live by the current lowest price.

How much VRAM do I need to get started?

16GB is a fine starting point for coursework and inference with models ≤7B; fine-tuning wants 24GB.
