FAQ

Billing​

Why am I still being charged after stopping an instance?​

Because the disk is still reserved for you. Stopping ends compute charges only; storage continues per GB-month. To stop paying entirely, destroy the instance.

This is the single most common question, which is why it appears on the pricing page, in the order drawer, on the instance list and in Billing.

I ran for 90 minutes — is that 1 hour or 2?​

1.5 hours. Metered per second, priced per hour, no rounding up.

Do I pay while the image downloads?​

No compute (the instance is not running yet) but yes storage (the disk is already allocated).

Can my rate change after I order?​

No. It is locked at order time and holds until that instance is destroyed. Market moves only affect new instances.

Will my data be deleted the moment my balance hits zero?​

Not immediately. The sequence is: warning emails → balance exhausted, instances stopped → only after the balance stays negative past a set period are they destroyed. Topping up in between restores everything.

Instances​

How long does booting take?​

Usually 1–3 minutes. Larger images, or a machine that has not cached the image, take longer; the page shows elapsed time.

Can destroyed data be recovered?​

No. Destroying releases the disk and we keep no backups. Copy results out first.

How many instances can I run at once?​

No cap beyond your balance. Running several in parallel is common for batch work — the total cost matches one instance running the same total time, but you get results sooner.

Is the machine shared with anyone else?​

An instance is a container allocated exclusively to you. The "Resource allocation" block on the Advanced tab states how the physical machine is allocated.

Can I expand the disk later?​

No. Disk size is fixed at creation. Provision enough up front — but not too much, since it bills continuously.

Connecting​

SSH says Permissions 0644 for 'nexgpu_key' are too open​

The key file is too permissive:

chmod 600 nexgpu_key

My service is running but unreachable from outside​

Check three things in order:

  1. Is it listening on 0.0.0.0 rather than 127.0.0.1?
  2. Is the port one of those in the Advanced tab's mapping table?
  3. Are you using the public address (second column), not the container port?

Can I add a port?​

No. Port mappings are fixed when the container is created. Decide before ordering how many services you will expose. Ports 9000–9009 are reserved for your own use.

Jupyter warns "connection is not private"​

Expected — direct Jupyter access uses the instance's self-signed certificate. The page explains it; continue past the prompt.

I am not comfortable with the command line​

Click "Install control panel" on the instance page and manage files, processes and software from the browser. See Control panel.

Choosing a GPU​

How much VRAM do I need?​

Depends on the workload — see the table in Choosing a GPU. When unsure, rent the cheap card first; it costs cents per hour.

What happens if VRAM is short?​

Either it will not run at all, or the framework offloads layers to CPU and slows down noticeably. Choose an environment first and the market flags machines that cannot run it, with the reason.

Consumer (RTX 4090) versus datacenter (A100)?​

Consumer cards give the cheapest compute per dollar and suit image generation, LoRA fine-tuning and small-to-mid inference. Datacenter cards have more VRAM, faster interconnect and hold up better under sustained load, suiting large-scale training and high-concurrency serving.

Account​

The verification code never arrives​

Check spam. Otherwise try another address or message Telegram support.

Can I get an invoice?​

Yes. Email [email protected] with your legal entity and invoicing requirements.

Which payment methods are supported?​

USDT (TRC20) and Alipay. See Top up.

Still stuck?​

Include the instance number and time range and you will save a round trip.
