Latent Recurrent Transformer: Architecture Exploration, Training Strategies, and Scaling Behavior
arXiv:2605.26797v1 Announce Type: new Abstract: We study Latent Recurrent Transformer (LRT), a lightweight augmentation of autoregressive transformers that reuses a high-level source-layer hidden state from the previous token as recurrent memory for the next token. Because this source state is already computed during ordinary decoding, LRT adds a cross-layer recurrent latent pathway across positions without inserting pause tokens or extra depth loops, and the standard attention mechanism and KV-cache interface are preserved. To pretrain this recurrence at scale without sequentially unrolling t
This research emerges as the AI community intensely explores methods to enhance the efficiency and scaling of transformer models, balancing performance with computational cost.
A more lightweight and efficient transformer architecture, like LRT, could significantly impact the development and deployment of larger, more capable AI models, potentially democratizing access to advanced AI capabilities.
The proposed Latent Recurrent Transformer introduces a novel way to improve memory and efficiency in autoregressive models without sacrificing standard attention mechanisms or requiring major architectural overhauls.
