International Conference on Learning Representations ICLR 2026
Turing Machine Imitation Learning (TAIL) is a synthetic chain-of-thought framework that instills Turing machine–like execution in LLMs, enabling robust length generalization for computable reasoning. On 18 challenging tasks, a 7B TAIL model outperforms the 671B DeepSeek-R1, establishing a new state of the art.
