The computation power is there, and is good, your server wont crash and it will work well, however there's a bit of shortage since a lot of times you cant use your own server because the gpu is being used by another user, and while you wait for it to be avayable you are still getting billed for the storage. At start, I had a terrible experience where some misleading text would lead to some unexpected payments, but finally the support team realised the mistake and refunded the full amount, so I'm OK with that. Is vast.ai worth it? If you don't mind waiting for your turn while paying storage and also can get thru the misleading text, servers arent bad...

We aim to respond quickly on customer support but due to time zone differences (we are based on Pacific time), there can sometimes be a delay in response. EDIT We pulled up your customer information and saw that your customer support chat request didn't get resolved. We have issued a refund for the misunderstanding and for your feedback. FYI for any readers - Our billing system is similar to Amazon Web Services and Google Cloud Compute where you get autobilled for usage at certain billing thresholds. We don't delete instances automatically, so if you leave something running it will accumulate storage charges which will then trigger autobills. Check the billing page for details. Always delete instances on Vast.ai when you are done using them.

Good intentions and pricing, but so far so-so execution. My custom Docker image did not let me use GPU in TF or PyTorch, and yet the site info said it should be compatible (not with newer CUDA drivers, no - it cannot be, as these drivers are not backward compatible). My custom Jupyter token did not work, and they did not know why. They auto-generated Jupyter token even though I specified my own with a properly set env. variable. The SSH tunnel option did not work... the machines refused SSH connections. I got disconnected after a mere hour of working because the PC (which it was, with a GPU that had an actual fan - meaning: retail hardware, not a proper datacenter GPU, double-check please if you are not violating NVIDIA's hardware licensing agreements by hosting retail hardware like that, in a mock-datacenter fashion). Anyway, I pressed "report this machine" button and it went up again soon, so I did not suffer any data loss (maybe the PC's Jupyter notebook server or other system server simply went down, which the website reported in a very hysterical manner that the machine was "no longer part of their network"). A notch better SLA than an anonymous proxy, because you have actual tech support. Extra star given for the CUDA driver compatibility tests that I managed to conduct (the info provided on each server is very detailed, e.g. on max CUDA version). I hope these are just budding problems, and they will get better soon! Update: I've tested also the Interruptible instances. Waited until I got outbid (for cheapest instances it happens after an 1 hour or so). Then tried to transfer the data out from the stopped instance (you pay for storage of non-running instances precisely for that reason), using the Copy functionality (having spinned up another instance as target). It failed with "Invalid input format" error - I had a text file (JSON) and a binary file (a JPEG). So don't choose these instances if you value your data until such bugs are fixed - if you get outbid, you won't be able to access your data anymore (unless you wait for it to be returned by the person who outbid you, which I did). Update: I was unable to make my containers work with their service, because of non-standard execution mechanisms (these containers work perfectly under both docker and k8s). They still kept charging me even though I could not log in. I subtracted 1 star for being unable to withdraw my money (you have to pre-pay at least 5 USD - I paid 10 - and there is no self-service way to get the unused balance back). I subracted one more start for the age of this service. I've found out that it is now ... 5 years old and it's still full of bugs ("Piotr Inny 15 października, 2018 | 8:26 am Ta usługa to faktycznie beta, niestety pełna bugów."

Hello Mirek. Thank you for the feedback and detailed bug reports! I think you left this review at 5AM our time, which is a few hours before we could meaningly respond to your support messages. The one machine you selected had a very low reliability score. Low reliability means that it has disconnected frequently and should only be used in a way that takes that into consideration. That explains your SSH issue and fear of data loss when the machine disconnected. Machines with long periods of uptime with no problem will have a higher reliability score. Your instance also quickly ran out of storage, which can also cause issues. Storage has to be allocated by the user when the instance is created. The Docker ecosystem that we currently use has some idiosyncrasies. With a little guidance from our support channel, we were able to get you answers to the questions and issues posed above. I hope you could amend your review to be a bit more positive now that you have met us and gave you a better context of your experience. With time, hopefully we can win you over as a happy customer.

Wanted to ask something related to the machine specs I rented and reached out via the online chat. Super fast response from Jake and addressed my queries in no time. 5 stars customer service!

The best prices and options for consumer GPUs and easy to start and scale up. Some machines don't work for various reasons though so you end up having to test and eval them yourself. Support is active and helpful during US office hours, not as much off hours. Still the best place for cheap GPU compute.

My favourite service for Stable Diffusion. Really love this website. Good prices for renting GTX4090. All informations are clear. I'm using vast.ai servers for about 4 months already and I didn't encounter any disconnects yet. All negative comments here seems to be written by people with low IQ who can't read FAQ or are too lazy to read things and then cry. Anyway, website is great. All you need to do is to get a server with good learning rate and low ports amount. Then it should work great.

Changed the review. They gave me my money after two days back.

Watch out when you use this service. they will keep charging when you stop the service. and for me, it was not clear that that was the case so I had to pay even if i didn't use the service.. could not get a refund or anything. really disappoining.. and such a waste...

Sorry you had that issue. We have a clear warning where you enter your credit card that storage fees accumulate on stopped instances. We also have a warning when you stop the instance that storage charges will accumulate, which you have to click. As you could understand, we do not want to delete data and storage is not free on the platform.
