How do you enable GPU servers?

My Claude keeps trying to use a GPU server which we want to setup for image/video processing. It keeps returning that it is an account feature that needs to be opted into. I do not see that anywhere in settings. Can someone help me with some guidance please?

Hi… The official docs say that GPUs are being phased out, so it may not be possible to sign up now, :crying_cat:

GPUs are deprecated and will be unavailable after August 1.
