What does a compute unit measure?
A compute unit (CU) is a usage balance consumed while running Colab resources. How quickly it is used depends on the runtime and resources available; it is not a promise of a fixed number of hours.
Why is there no fixed number of GPU hours?
Google does not publish a fixed CU-per-hour rate for each GPU. Resource limits and available GPU or TPU types vary over time. Check the “Resources” panel inside Colab for the current rate and remaining balance. Premium GPUs and high-memory machines depend on availability and your balance. Google’s Colab FAQ also says resources are not guaranteed, limits vary and are not published.
What is included in the shop’s account?
The shop provides a private account with 500, 1,000 or 1,500 CU, for one user until the end of the purchase month. The 500 CU tier is in stock; 1,000 and 1,500 CU are on request, and the Telegram bot confirms availability before payment. See the 500 CU plan and the price list.
What happens if the CU run out before month end?
When a paid user’s balance is exhausted, Google says Colab reverts to free-tier policies. You can order another account if needed; unused CU do not carry over. Pro+ supports continuous code execution for up to 24 hours when enough CU remain, but this is not a guaranteed runtime.
What happens to the account at month end?
The shop-provided account is revoked at the end of the purchase month, possibly during the night of the 30th–31st. Data is not retained. This is part of the account terms, not a service fault covered by the warranty.
Where should I back up my data?
Back up notebooks, checkpoints and data to your personal Google Drive or own machine after important sessions, especially during the final three days of the month. The shop does not retain account data.
When should I choose 1,000 or 1,500 CU?
Choose a larger balance when your workload needs more compute units and you have checked current usage in Colab’s Resources panel. The 1,000 and 1,500 CU accounts are on request, so ask the Telegram bot to confirm stock before paying. Google prohibits cryptocurrency mining and using multiple accounts to work around resource restrictions.
