Vast.ai Reviews 229

Helped me fast and well. There was no problems with contacting a host and getting the help i needed, thanks!

My experience with VAST.ai has been extremely disappointing and frustrating. The service advertises GPU instances, but in practice many of these appear to be containerized environments rather than true dedicated machines. This creates serious reliability concerns for users who require stable and predictable infrastructure.

One of the most problematic issues is that when an instance is stopped, it often disappears from availability. When attempting to restart it, the system simply goes into scheduling mode for extended periods without successfully launching the instance. For users running workloads that depend on consistent GPU availability, this behavior makes the platform highly unreliable.

In addition to the infrastructure issues, the quality of customer support was also very unsatisfactory. My interaction with a support agent named Saber did not lead to any meaningful resolution, and the responses I received lacked clarity and helpfulness. For a platform providing paid GPU infrastructure, a much higher standard of technical support should be expected.

Overall, the experience gave the impression of an unstable platform with insufficient support for customers. For users considering VAST.ai for serious workloads, I strongly recommend carefully evaluating the platform and its reliability before committing to it.

I hope the company takes these concerns seriously and improves both its infrastructure stability and the quality of its customer support.

fast good reliable, what to say more ? that just perfect and w to the support who is fast and good :)

A really top of the notch customer support. I lost my GitHub account so the login into my vast ai account. I contacted the support and they where able to refund me my money.

The customer service is great!

Bach is fantastically technically competent, to the point that they took a problem that I thought was super complicated and dissolved the whole thing by trying it straightforwardly. They have excellent problem solving and debugging skills, and were a tremendous help. I'm going to spend a bunch of money on vast.ai because of them!

It's been fun setting stuff up with them. You won't have root access to the containers, but their Docker containers and their marketplace have been sufficient to get me good remote desktop into a GPU-heavy CAD application at the cheapest price anywhere!

Vast.ai is one of the most useful vendors I've used. Both in corporate and small business. They are responsive, knowledgeable, and helpful. As the market shifts to decentralized clouds and consumer hardware, Vast.ai will far exceed its competitors. Great support team!

I started using Vast.ai yesterday, and to say the least, I’m quite mixed about the experience. I had to rent five different instances before finding one that actually worked, which was a waste of both time and money (not a huge amount). It’s honestly hair-pulling frustrating.

Many of the lowest-priced instances are full of bugs and issues. In the end, those supposedly cheap options don’t function properly, and the ones that do work are the more expensive ones. Maybe I was just unlucky, I’m not sure yet, but so far my impression is very mixed.

Awesome customer service - always helping and the people on the other end of the chat are like microcenter employees - they are all nerds with great skills and helping and teaching.

the answer fast and get very good solutions

I encountered a connection issue with a machine. The customer service replied to me in a few minutes. It turned out that the connection issue is due to my network side. I am well-satisfied with the conclusion in short.

Smooth AF
Value for money.
Wallet recharge system is responsible of them, no predatory vibes.
Vast options for GPUs

Vastai is an amazing GPU marketplace. They support custom docker images and everything works smoothly. Both for casual users and experts

The prices and customer service are amazing. I've used other cloud providers before, and they don't compare to VAST.

100% recommended

I've hosted a few machines with Vast.ai over the last 2-3 years. As a side hobby it's OK, but I recommend serious businesses stay away.

The machine verification process is opaque and arbitrary. There is no guarantee when it will happen, and only vague guidelines to "keep the machine online" and "it depends on demand", even though "it's an automated process".

Machine maintenance is problematic, since reliability score is impacted whenever a server is restarted, even if to apply critical security patches. Using a maintenance window, and ensuring there are no current clients, still impacts reliability score. This encourages hosts to leave machines online without security patches, to retain reliability scores.

The support team really impresses me !

A few time, I encountered unexpected situations or needed advising. Through their chat online, which is 100 % human, they always show quickly available and give a great support. This is remarkable and their offer solutions for all budgets. Try it and enjoy your work with them.

These people care about what they do. They are easy to reach, and always helpful. Best integrated support chat I have seen on any website. I'm impressed by their character, and will choose them over any competitor.

Service is not good, your instance gpus can get scheduled from another guy and you have to copy data which costs bandwidth to another instance just so you can open another even if its targeted as "on demand" your still off better going for competitor sites i dont recommend it at all. Customer service is bad as well they seem like they get paid minimum wage and dont even care to help you just give you some copy pastes or some ai bs

Incredibly frustrating some machines fail to do even the most basci things
