If you use verified machines then it's an amazing and cheap service Non verified machines may be bad, offering bad connections and may be unavailable once rebooted, hence the many bad reviews. For this reason, I suggest you to only stick with verified datacenters. I rented an A4000 GPU for many hours and I've never had any problems with internet speed or availability. The price is very convenient at about 0.16$/h. Nothing to complain about, for me it was essential to train some DL models at a small price. Very recommended.

Horrible experience Horrible experience! There was no confirmation email sent to the main box nor spam (waited and refreshed after 24 hours) so I couldn't use the service even if I credited the account with 10$. So basically useless. Also, I forgot my password, and after trying to reset my password, the button reset doesn't work on multiple browsers. Don't use it !!

Livechat is lacking, servers are good but a lot of waiting time 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...

Watch out when you use this service 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...

My favourite webaite for working with Stable Diffusion 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.
