If you get the Llama weights from Meta directly, you need to make an account [1] and hand over your "full legal name, date of birth, and full organization name" (and presumably click 'agree' on a click-through agreement) before they'll let you download them.

You can sidestep this by just downloading someone else's quantisation / fine tune.
