Vast requires pre-payment of credits for GPU rentals. Once credits are purchased, they appear in your account balance.

We accept credit card payments through Stripe and crypto payments through Crypto.com and Coinbase. Use the add credit button to purchase credits one-time. Use the auto-debt feature to have the system automatically top up your account using a saved credit card when it runs low.

Vast does not automatically destroy your instance(s) and data once your balance reaches zero.

Whenever your balance reaches zero or below, your instances will be stopped automatically but not destroyed. That way the data is still available for you to copy off the instance. Since the data is still stored on the instance, you are still billed for storage on stopped instances even when your balance is negative.

Your credit card will be automatically charged periodically to pay off any outstanding negative balance. Instances appearing in your account are never free.

You can set a balance threshold to configure auto debits, which will attempt to maintain your balance above the threshold by charging your card periodically.

We recommend setting a threshold around your daily or weekly spend, and then setting an balance email notification threshold around 75% of that value, so that you get notified if the auto billing fails but long before your balance depletes to zero.

There is also an optional debit-mode feature which can be enabled by request for older accounts. When debit-mode is enabled, your account balance is allowed to go negative (without immediately stopping your instances).

Balances are updated about once every few seconds.

Vast.ai does not see, store or process your credit card numbers, they are passed directly to Stripe (which you can verify in the javascript).

After spending credits, there are absolutely no refunds.

For unspent credits, contact us on the website chat to request a refund. In most cases we can refund unspent credits. Unfortunately Coinbase Commerce does not support refunds, so there are no refunds possible for credits purchased via Coinbase Commerce.

There are separate prices and charges for:

You are charged the base active rental cost for every second your instance is in the active/connected state. You are charged the storage cost (which depends on the size of your storage allocation) for every single second your instance exists and is online (for all states other than offline). Stopping an instance does not avoid storage costs.

You are charged bandwidth prices for every byte sent or received to or from the instance, regardless of what state it is in. The prices for base rental, storage, and bandwidth vary considerably from machine to machine, so make sure to check them.

You are not charged active rental or storage costs for instances that are currently offline.

To see a pricing breakdown on your current instances within your Instance page in the console or from offers on the Search page you can hover over the price to see pricing details.

We currently support major credit cards through stripe and crypto payments through Coinbase and crypto.com.

In this section we will walk through the Billing page you can find within the Console when logged into your Vast account.

Here you can see the current amount of Vast credits you have. This section also shows your current credit spend given your current instances. You can also view your transactions and generate invoices here.

In this section you can add payment methods and add credit to your account.

Here you can add the information to be shown on invoices you generate.

Here's an example that shows where and how the invoice info appears on generated invoices:

If you leave your Invoice Info blank it will default to your Vast account's email address for the "Bill To:" information.

You will only be charged for the 10 minutes of usage.

If you pay with credit card you can get a refund on unspent Vast credits. We do not refund Vast credits bought with crypto.

Pricing is fixed by the host, and is specific to each machine and contract. You can refine your search and look for a machine that suits your needs here.

Before buying credit with Stripe you must add a card!

No, you are not charged when it says "Loading".

It says in the Billing page: "You have a negative credit balance. Your instances are stopped and can resume once you pay the balance owed".

You may be see your Vast credit decline at a greater rate than expected due to upload and downloads costs, which is not shown in your $ cost/hr or $cost/day pricing breakdowns as it is charged on a usage basis and not a constant rate. You can find these rates for bandwidth usage in the Internet: section of the pricing details, which you can see when you hover over the price in the bottom right-hand corner of instance cards within the Instance console page. You can also see pricing detail before instance creation from hovering over the prices on the Search page. You can also get a detailed document of your billing history by "Generate Billing History" within the Billing page of the console.

There are over 10,000+ listings on vast, and search only displays a small subset. You will usually not be able to find any one specific machine through most normal searches. To test that your machine is listed correctly, you can use the CLI: vastai search offers 'machine_id=12345 verified=any'

Replace 12345 with your actual machine ID If your machine is verified, you should still be able to find it without the verified=any.
