FlowState：用执行状态做记忆的长时程 LLM 智能体框架
FlowState: Execution State as Memory for Long-Horizon LLM Agents
AI 导读
针对长时程任务中保留完整历史推高上下文成本、压缩历史又丢失细节的问题，研究者提出 FlowState，将执行状态作为可跨请求保留与回访的记忆。它保留语义化状态节点及其关系和对原始工具观测的引用，通过增量状态更新（ISU）与渐进式状态访问（PSA）在推理中按需展开历史。

Abstract:Long-horizon tasks require LLM agents to continually draw on information from earlier interactions. However, retaining the full history increases context costs, while compressing it risks losing details needed later, and the relevance of historical information often becomes apparent as the task progresses. To address these challenges, we propose FlowState, which treats execution state as memory that can be retained and revisited across requests, unifying current decision-making with the reuse of historical information. FlowState preserves semantically typed state nodes, their relations, and references to raw tool observations, separating persistent retention from on-demand access. Within a single execution loop, Incremental State Update (ISU) maintains the current state based on new inputs and feedback, while Progressive State Access (PSA) progressively reveals historical states and supporting evidence as needed during reasoning. Together, these mechanisms enable agents to reassess prior decisions in light of new information and guide subsequent actions. Compared with a full-context baseline using the same DeepSeek-V4-Flash model, FlowState improves the average success rate on MemoryArena and the average pass rate on $\tau^3$-Bench by 4.55 and 13.95 percentage points, respectively, while reducing total token consumption by 43.2% and 40.6%. These results demonstrate the performance and efficiency advantages of FlowState on long-horizon tasks.
