Still pretty expensive IMO. I'm building a GPU accelerated signal processing web-app, and I'm currently planning to deploy it on a $180 Nvidia Jetson. Performances are a little bit low, but mostly enough to make the app usable. I tried to find GPU instances for Does anybody know cheaper GPU instances? I don't need much computing power, about 0.5Tflops to 1TFlops
Our lowest at Genesis Cloud at this time are instances with an RTX 3060Ti for 0.20$/hour which adds up to 146$/month ( https://www.genesiscloud.com/pricing#nvidia3060ti ) Though, this includes free storage, no egress fees and has a lot more power than a Jetson.
If you need to optimize for low cost hosting, did you already check whether you actually must have a GPU for your use case? Modern CPU have some impressing capabilities.
