Vast.ai Reviews 

Had an issue with an instance, reached out to customer support, and they were extremely friendly and were able to resolve the issue straight away!

I was trying to setup ubuntu server based GPU hosting for 5060 ti, which was not even having proper driver till recently. I am a complete noob and did all stages using Chatgpt(it was hell). However, the support from vastai was nice, considerate and responsive. Thanks to the team.

Really helpful, problem solved with the help of the support team.

Vast.ai is the best AI cloud out there. Best prices and fast support 10/10.

Problem fixed by Marco on the support chat channel. Patient, human and helpful. Couldn't ask for 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 Most of the servers are very outdated, with terrible disks and poor internet connections.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.

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

well the CS super helpful, especially for newbie that not really used to VM access

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!

So Good , very Good

all good, questions solved

I love this company! Great support and awesome machines!

Great and reliable service!

I had awesome support from Marco through the chat support. He answered all my questions very clearly, and was patient throughout the whole process.

Support is rapid. It's easy to use.

Everything was answered properly and quickly, with simple and clear language and tone.

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.

As usually they have a great support and the service is also great I recommend.

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.

Great customer service, fast and responsive, and solved my issue quickly on a Sunday morning.
