Researchers have devised a lightweight uncertainty-estimation technique that examines cross‑layer agreement patterns in large language models. By scoring internal representations in a single forward pass, the method rivals traditional probing while being far more efficient.
The Signal
Demonstrated on three leading models, it consistently outperforms existing approaches, offering a scalable path to more reliable AI systems globally.
