arXiv:2603.20508v2 Announce Type: replace-cross Abstract: Reasoning language models (RLMs) and the intermediate chains of thought they emit play an increasingly central role in multi-agent setups such as inter-model monitoring or distillation into smaller models. When agents at different capability tiers must cooperate, strong models need to produce traces digestible by weaker ones. We refer to this goal as "weak-to-strong legibility". Trustworthiness of large models depends in part on this legibility property. For safety oversight in particular, adoption of weak monitors may become a standard
The increasing deployment of AI models, particularly in multi-agent systems and safety-critical applications, necessitates robust methods for understanding and verifying their internal reasoning processes.
The concept of 'weak-to-strong legibility' directly impacts the trustworthiness, safety, and scalability of AI systems, especially when ensuring oversight by less capable models or human operators.
The focus on legibility as a measurable property introduces a critical metric for evaluating and designing future AI models and multi-agent architectures, emphasizing interpretability for safety and collaboration.
