Dual-Slot: From Serial Loops to Parallel Slots in Language Models

Yiqin Hao, Zitong Wang, Boyi Zeng, He Li, Shixiang Song, Feichen Song, Yifan Liu, Zhouhan Lin

Processes a latent slot and a prediction slot together, carrying the previous token's hidden state into the current prediction. Uses parallel iterative updates during training while preserving autoregressive text generation at inference.

Recurrent reasoning — Repeat parts of the model or keep intermediate information in memory while working through a problem. Some methods also learn how many passes to run.

Alternative generation methods — Change how intermediate steps are generated, revised, or searched—for example, by refining several steps in parallel. Some produce written chains of thought.
