AdaPlanBench: Evaluating Adaptive Planning in Large Language Model Agents under World and User Constraints

arXiv:2606.05622v1 Announce Type: new Abstract: Planning for real-world problems by language models often involves both world and user constraints, which may not be fully specified upfront and are progressively disclosed through interaction. However, existing benchmarks still underexplore adaptive planning under such progressively revealed dual constraints. To address this gap, we introduce AdaPlanBench, a dynamic interactive benchmark for evaluating whether Large Language Model (LLM) agents can adaptively plan and re-plan under progressively revealed world and user constraints.

Why this matters
Why now

The rapid advancement and deployment of Large Language Models necessitate robust evaluation benchmarks for their practical application in complex, dynamic environments.

Why it’s important

Evaluating LLM agents' adaptive planning capability under evolving real-world constraints is crucial for their reliable and autonomous deployment in critical white-collar workflows.

What changes

The introduction of AdaPlanBench provides a standardized, dynamic tool for assessing a key limitation in current LLM agents, pushing towards more resilient and capable AI systems.
