A Princeton researcher, Yifan Zhang, has proposed a novel architecture called the Recurrent Looped Transformer (RLT). This design aims to enhance the temporal depth of decoder-only language models by carrying the complete state, including the final hidden state and layerwise attention caches, from one token to the next. The RLT architecture features a causal encoder and a recurrent decoder, with each token processing involving 96 logical blocks. While the design specifies principles for latent reasoning with unbounded temporal depth, model-hardware co-design, and model-RL algorithm co-design, it currently lacks measured results on efficiency, reasoning quality, or scaling.
