Right now one RTX 5000 Ada at $0.54 an hour; RTX 5090 at $0.68 an hour is the best value for its speed. Prices are live offers from GPU clouds, checked every 15 minutes.
Can Flex.1-alpha run on an RTX 4090?
Not on one: it needs about 30.3 GB and an RTX 4090 has 24 GB. An RTX 5090 (32 GB) is enough.
How do I deploy Flex.1-alpha as an API?
Pick a machine on its GridPup page and press Deploy: GridPup rents the GPU, downloads the model from Hugging Face and serves it at an https address with keys and OpenAI's image API, billed by the hour.
Prices are per hour for the whole machine and its disk, right now. Speed is Vast's DLPerf score of the machine, relative to the cheapest. Best value: the most speed per dollar. Only machines with a Vast reliability above 95% that download at 400 Mbit/s or more are offered: the machine fetches the model itself.
