Earlier quoted context omitted.
The rule of thumb is roughly 44gb, as most models are trained in bf16, and require 16 bits per parameter, so 2 bytes. You need a bit more for activations, so maybe 50GB? you need enough RAM and HBM (GPU RAM) so it’s a constraint on both.
Which GPU card can I buy to run this model? Can it run on commercial RTX3090 or does it need a custom GPU?
Though realistically for code completion smaller models will be better due to speed
