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.
Response from Vast.aiMay 25, 2025
Hi F P, We’re truly sorry your first experience with Vast.ai fell short. The Stable Diffusion template you used should have worked, and it’s clear we let you down—first with the technical issue and then by not responding promptly. We’ve now issued a full refund of all your charges. Because the workload was deleted more than two weeks ago, we no longer have the logs needed to re-create and diagnose what went wrong. That said, we’re reviewing our templates and support workflows to prevent a repeat of this situation for anyone else. Thank you for the candid feedback. It helps us improve. — Vast.ai Support

Hervorragender Support & zuverlässige Plattform Ich habe am Wochenende meine Maschine bei Vast.ai neu eingerichtet und war begeistert vom Support – besonders Matthew war unglaublich hilfsbereit. Die Unterstützung war technisch fundiert, lösungsorientiert und freundlich. Selbst bei komplizierten Netzwerkfragen wurde ich nicht allein gelassen. Vast.ai ist nicht nur technisch eine starke Plattform, sondern auch menschlich sehr unterstützend. Vielen Dank!

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.
