A Paper Retrofits Recurrent Depth Into an Already-Trained Language Model
Researchers split Qwen2.5-0.5B-Instruct into a prelude and a weight-tied recurrent block, and report the learned iterative latent transition survives outcome-only annealing.
Recurrent depth, the idea of letting a model repeat a block of layers a variable number of times instead of running a fixed stack once, has mostly been studied in models trained that way from the start. A paper posted to arXiv asks a cheape…

Part of a tracked trend
Frontier Model Efficiency Gains
Capability per unit of training and inference compute keeps improving, letting newer models match prior frontier performance far more cheaply and gradually loosening the link between raw scale and capability.
