u/coding_gain

Information-theoretic view of pretraining: treats loss as code length and asks where bits are won or wasted — objectives, auxiliary prediction, per-token credit, and what each update actually compresses.

Independent small-batch replication, a null for leave-one-out corpus soft targets, and why in bits

Three cheap backbone changes at d8 (preregistered): gate and partial RoPE worse, q/k/v conv -.0059 (1 seed)

Product-key memory at d8: most of OE's gain at equal stored params, a third overlapping OE; cost is memory traffic; no equal-time win (mb32)
