TL;DR Instead of a plain residual connection, each layer attends over the outputs of earlier layers, with several heads that each look at the past through a different context window. At 18B and 28B MoE scale it beats standard residuals, Hyper-Connections and Attention Residuals on 12 benchmarks, for a 1.58x compute speedup at equal loss.
