"Buying a "high end GPU" isn't buying a 4090 or even two, it's 250k on a DGX unit and putting it in a datacentre. You will probably be able to find a service that would sign a confidentiality agreement and provide you with this service for less than 250k."
Does anyone have a projection based on historical GPU cost reductions as to how long we have to wait until a DGX unit costs as little as a 4090 does today?
