📖 Full Retelling
A team of academic researchers published a new study on the arXiv preprint server early in February 2024 to investigate the internal robustness of Reasoning Large Language Models (RLLMs) against disruptions in their step-by-step logic. The study addresses a critical gap in artificial intelligence safety by analyzing whether these models can maintain accuracy when their ‘Chain-of-Thought’ (CoT) processes are intentionally interrupted or altered during the generation of a complex answer. By introducing a controlled evaluation framework, the scientists sought to determine if the transparent reasoning traces often cited as a benefit of modern AI are actually resilient or merely fragile sequences that collapse under minor pressure.
To conduct this experiment, the researchers designed a series of seven distinct interventions categorized as benign, neutral, and adversarial. These perturbations were applied at fixed timesteps within the model's own reasoning cycle, forcing the AI to contend with modified information or interrupted logic while mid-process. The primary goal was to see if the RLLMs could self-correct or if the perturbations would lead to a catastrophic failure in the final output, regardless of the model's initial capabilities. This methodology moves beyond traditional benchmarking by looking into the hidden 'thought' layers of the transformer architecture.
The findings highlight a significant vulnerability in current RLLM architectures, suggesting that while the step-by-step reasoning improves performance on difficult tasks, it also introduces new points of failure. If a model's logic is easily derailed by external interference or internal inconsistencies, the transparency provided by the Chain-of-Thought may be less reliable than previously believed. This research is particularly relevant for the development of more stable AI systems in fields like mathematics, programming, and complex decision-making, where the accuracy of the process is as vital as the final answer.

arXiv:2602.07470v1 Announce Type: new Abstract: Reasoning LLMs (RLLMs) generate step-by-step chains of thought (CoTs) before giving an answer, which improves performance on complex tasks and makes reasoning more transparent. But how robust are these reasoning traces to disruptions that occur within them? To address this question, we introduce a controlled evaluation framework that perturbs a model's own CoT at fixed timesteps. We design seven interventions (benign, neutral, and adversarial) and
