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...

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.

Vast.ai offer is strong Despite some raw edges, Vast.ai offer is strong. I managed to escape this crappy Kaggle-to-Colab-and-back tinkering with frequent disconnects and got very powerful and manageable workflow with remote jupyter kernel from vast.ai machine inside local VS Code.

Good service The service Is good and Very user friendly and cheap. Also support Is really nice and friendly but they take sometime to reply to us. Overall gread experience.

You get what you pay for... The service is cheap but the on-demand instance randomly disconnected me after a few days. Luckily I could reconnect before anyone else jumped on, otherwise it would be a total loss - all data gone. As expected customer service is nonexistent - "we'll be with you in just a minute" = infinite hold
