Distance between Relevant Information Pieces Causes Bias in Long-Context LLMs

ACL 2025finding

Positional bias in large language models hinders their ability to effectively process long inputs. A prominent example is the “lost in the middle” phenomenon, where LLMs struggle to utilize relevant information situated in the middle of the input. While prior research primarily focuses on single pie…

Generalizing Experience for Language Agents with Hierarchical MetaFlows

NeurIPS 2025poster

Recent efforts to employ large language models (LLMs) as agents have demonstrated promising results in a wide range of multi-step agent tasks. However, existing agents lack an effective experience reuse approach to leverage historical completed tasks. In this paper, we propose a novel experience reu…
