ByteDance Seed's Loop-μP paper draws 'Chinese loopmaxxers' buzz

scaling01 jokes he's "ready for Chinese loopmaxxers," pointing to ByteDance Seed's Loop-μP paper (with Tsinghua and M-A-P), which shows loop count destabilizes training and shifts optimal hyperparameters. Because shared weights make the residual stream grow linearly in N, they derive a Loop-μP parameterization (residual branch scaled by 1/N combined with L^(-1/2)); the base LR tuned on the smallest model stays best up to 8 loops and 384 executed layers — a practical recipe for scaling looped transformers.
