CoTFormer: Recurrent Transformers for Inductive Reasoning

Aras Kavuncu, Bryan Vullo, Alberto Berni· July 23, 2026 View original

Summary

This work evaluates CoTFormer, an architecture formalizing Chain-of-Thought as recurrent latent computation, preserving intermediate states for explicit reasoning. The study assesses its perplexity and compute efficiency, and extends evaluation to algorithmic settings to determine if this recurrent framework improves out-of-distribution generalization on inductive reasoning tasks.

The CoTFormer architecture conceptualizes Chain-of-Thought (CoT) reasoning as a form of recurrent latent computation within transformers. This design allows the model to retain intermediate states as attendable representations, effectively mimicking explicit reasoning traces. This research undertakes an evaluation of CoTFormer and its structural variations, focusing on key metrics such as perplexity and computational efficiency. Beyond standard performance measures, the study extends its assessment to controlled algorithmic environments. The primary goal in these algorithmic settings is to determine whether this recurrent framework can enhance out-of-distribution generalization, particularly on tasks requiring inductive reasoning. The findings aim to shed light on the potential of recurrent transformers to improve complex reasoning capabilities in AI models.
