| description = "Adam's two moment buffers are twice the size of the model, which is why 8-bit optimisers exist: each moment is stored as a byte index into a nonlinear 256-entry map plus one fp32 absmax per 2048-element block. Every step has to dequantise both moments through that map, take the AdamW step, and requantise against a NEW block absmax that is not known until the whole block's new moment exists. It is the memory-heaviest kernel in the training loop and it is all bandwidth and lookups." | |
