Researchers have introduced STT-Arena, a new benchmark designed to evaluate large language models' ability to adapt and replan in dynamic environments with spatio-temporal changes. The benchmark consists of 227 interactive tasks that simulate real-world scenarios where mid-task disruptions can invalidate existing plans. Evaluations showed that even state-of-the-art models like Claude-4.6-Opus struggle with these dynamics, achieving less than 40% accuracy. The research also identified common failure modes in LLMs, such as executing with stale states or misdiagnosing dynamic triggers, and proposed a technique to improve adaptive replanning capabilities.
