Unverified50% confidenceOpinionExact time
Chain-of-Thought is essentially performing explicit recurrence at the token sequence level, whereas recurrent Transformers attempt to internalize iterative capability into the network structure, allowing repeated reasoning to occur in latent space.

UnverifiedRecurrent Looped Transformer proposes having part of the model's layer structure be invoked repeatedly in a recurrent manner, providing variable reasoning depth without increasing the number of parameters.69% similarUnverifiedThe recurrent architecture is analogous to the unrolling of a classical RNN across time steps, except that the object being recurred is the Transformer block itself.68% similarUnverifiedCompared with the early chain-style calls of LangChain, LangGraph supports cyclic execution, conditional branching, and persistent state68% similarUnverified图结构支持条件分支、循环迭代和并行执行，这与传统线性链式调用（Chain）有本质区别68% similarUnverifiedChain-of-Thought 是一个封闭系统，推理过程无法感知外部状态变化，而 ReAct 是开放系统，每次工具调用都注入外部环境的新信息68% similar
