Multiple GPUs?

I have several systems with multiple GPUs (6x3070 or 3080ti) available. Would video enhance AI be able to use the power of all 6 GPUs to do the work a lot quicker or is only the first GPU used?
Yes, these are crypto mining rigs but can easily be booted into a windows environment for this purpose.


The forum search works.
