Beyond Memory: Harnessing Long-Horizon Agents with Explicit Belief Statesarxiv.org

PoS is an inference-time framework that constructs and maintains explicit belief states for LLM agents, combining world state and unresolved task requirements. It validates consistency and detects "Belief Trapping" to ensure progress, achieving superior performance on long-horizon execution and diagnosis benchmarks across multiple LLM backbones.
