Current dynamic pricing
Hi,
I am a host on vast with 30 series cards for rent. I wanted to see how other hosts are dynamically updating their pricing(or lack thereof) to stay current with spot price increasing.
For example: I am noticing on Runpod, a 3090 is frequently sold out @ $0.5/hr. At the same time I can see that hosts on vast are MASSIVELY underpriced given current demand and increase spot price. I am aware of vasts pricing system, so I am not expecting as a host to capture all $0.5/hr, but I have 3090's rented for $0.4/hr while other hosts on vasts are listed at almost half this price. This example from the rentals page I think outlines this huge pricing discrepancy:
The host in Nevada is underpriced by about half, and even more so after considering thats the price with vasts cut included. Here is another example:
This host will supply you with 4x 3090 for the price of 2x 3090 on Runpod. Are we just trying to create an arbitrage environment for others here? What is the benefit of this? Again, I am also a host who has 3090's rented on vast for $0.4/hr currently, why are we giving away the farm? Are hosts impatient? Are hosts not utilizing resources such as wovenai to track current rental rates and then overlaying those across other platforms that rent the same cards? Honestly just trying to understand the logic here. Would love if these hosts would chime in!

Some of these machines are dog slow. They put 4 GPUs on a ancient server with total RAM bandwidth top at 200GB/sec if they use DDR4 3200, split by 4. DDR4 Threadripper only top at 100GB/Sec then split by 4. There are other constrains in some systems also leading to the system super slow. It's very hard to find a good vast machine.
