# Towards Looped Models Done Right, Part I: Topology, Input Injection, Recurrent-State Design > Source: > Published: 2026-10-19 04:30:00+00:00 Looped language models reuse physical Transformer blocks across logical depth, but established architectures entangle recurrence placement, input injection, and recurrent state organization. We isolate these axes in models trained from scratch at matched parameter scale, logical depth, and token bud
