GPU.ai vs Octa.space
As of , GPU.ai and Octa.space share 4 GPUs today, but on none do both list an on-demand rate: at least one side is community capacity or a marketplace floor, compared below and not counted. On the priciest shared card, NVIDIA RTX 5090: GPU.ai $1.19 (from) vs Octa.space $0.51 (floor) per GPU-hour — not the same market, not counted. On other people's machines - community capacity and marketplace floors, a market of its own - GPU.ai lists the lower rate on 3 of the 4 shared GPUs. Compared apart ↓

Community capacity and marketplace floors, per GPU-hour
Capacity on other people's machines, compared on its own: a community rate is a fixed list price for a machine a third party hosts; a marketplace floor is the median of the five cheapest verified offers at the time of reading, and moves with supply. Either can be taken back sooner than an on-demand rate card, and neither enters the verdict above or any median.
| GPU | GPU.ai | Octa.space | Lower |
|---|---|---|---|
| NVIDIA RTX 5090 | $0.69 community captured | $0.51 marketplace floor captured | Octa.space, by $0.18 |
| NVIDIA RTX 4090 | $0.34 community captured | $0.75 marketplace floor captured | GPU.ai, by $0.41 |
| NVIDIA GeForce RTX 3090 | $0.22 community captured | $0.25 marketplace floor captured | GPU.ai, by $0.03 |
| NVIDIA RTX 4000 Ada | $0.20 community captured | $0.25 marketplace floor captured | GPU.ai, by $0.05 |
How this is compared
Cloud GPU rental prices of GPU.ai and Octa.space, compared per GPU-hour on the GPUs both list. Where a provider has several tiers or regions, its cheapest on-demand rate is used and labelled. Community capacity (RunPod Community Cloud) and marketplace floors are shown only where a provider has nothing else, and never decide which is cheaper.
