Octa.space vs Vast.ai
As of , Octa.space and Vast.ai share 8 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. Not compared today: 2 more shared GPUs, where one side's quote is not confirmed within 48 hours or is a thin market. On the priciest shared card, NVIDIA RTX 4090: Octa.space $0.75 (floor) vs Vast.ai $0.39 (Multi-GPU machines · 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 - Vast.ai lists the lower rate on 7 of the 8 shared GPUs. Compared apart ↓

Shared, not compared today
Both providers quoted these GPUs on-demand within the last 7 days, but at least one quote is not confirmed within 48 hours of the newest read (or is a marketplace floor withheld as too thin), and an unconfirmed price never decides which is cheaper. They return to the table above at the next read that confirms them.
- NVIDIA GeForce GTX 1660 Ti: Vast.ai: thin market
- NVIDIA GeForce RTX 5070: Octa.space: thin market
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.

How this is compared
Cloud GPU rental prices of Octa.space and Vast.ai, 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.
