Had a solid experience with Vast.ai so far. I was able to rent a decent GPU at a great price, and the setup was surprisingly smooth. I did run into an issue with SSH access on one instance, but su... See more

I can say this is the worst GPU rental site I’ve ever used. Most of the servers are very outdated, with terrible disks and poor internet connections. The good ones are extremely overpriced. Customer support doesn’t respond for almost an hour and doesn’t solve any issues. Even if you set up backups, they don’t work. They keep charging you even if the server goes down. I definitely do not recommend it.

Hi James,
We’re really sorry your rental didn’t meet expectations.
We’ve just sent you a private “Request information” via Trustpilot. If you can share the e‑mail or rental ID linked to your account, we will:
Issue a complete refund for the affected period, no questions asked.
Review your past support tickets so we can tighten our first‑response time and improve.
If you prefer, you can also reach us 24 / 7 at support@vast.ai—please mention this review so we can route your message straight to an engineer.
Thank you for bringing this to our attention. Your feedback helps us improve the platform for everyone.

Cheap servers great customer support
Cheap servers great customer support. Docs could be better but they ALways respond to chat so that can be forgiven. Plus where else can you rent a server with dual 4090's for less than $0.70/hr

Easy Affordable GPUs
Vast.ai is the best GPU cloud provider for technically minded people!
Being able to rent GPUs through a cli and programmatically control cloud GPUs via an SDK is a major win!
Being one of the most affordable cloud GPU providers with plenty of H100 and H200 offerings doesn't hurt either!

I had a few technical questions about my rig and was honestly blown away by the level of support. I received a reply within minutes, and everything was resolved incredibly quickly and with great care. This is exactly how customer service should work – responsive, friendly, and efficient. Huge thanks!

Awful company, first and last time I use their services.
I had a terrible experience with this company. Their official Stable Diffusion templates are flawed, producing outputs that lack prompt adherence, realism, and are often disfigured or distorted. I contacted them, but they ignored me and refused to refund me for the many hours I spent troubleshooting issues that were not my fault.

Hi F P,
We’re truly sorry your first experience with Vast.ai fell short. The Stable Diffusion template you used should have worked, and it’s clear we let you down—first with the technical issue and then by not responding promptly.
We’ve now issued a full refund of all your charges. Because the workload was deleted more than two weeks ago, we no longer have the logs needed to re-create and diagnose what went wrong. That said, we’re reviewing our templates and support workflows to prevent a repeat of this situation for anyone else.
Thank you for the candid feedback. It helps us improve.

Great business model, friendly support, but
Previous review:
------
Fantastic way to monetise your GPU if it's sitting there gathering dust.
Great community, and the support team has always been very helpful when I encountered technical issues.
New update:
------
Not friendly to hosts.
It has hidden listing rules that determine whether your instance appears in the renter's search results.
This rule has a huge impact on the visibility of your machine and thus rental. However, vast ai is not explicit about these rules.
As a result, my machine does not show up in search result most of the time, despite very competitive spec / cost. And there is nothing i can do.
