Semantic chunking computes embedding similarity between adjacent sentences or paragraphs and splits when it falls below a threshold; compared with fixed-length windows it makes topics within a chunk more coherent, but threshold selection relies on experience and the computational cost is higher.

UnverifiedPrecisely locating mention boundaries is more challenging than judging passage topics, as reflected in the performance gap between mention-level and passage-level metrics.75% similarVerifiedIn chunking strategies, chunks that are too large cause semantic focus to blur, while chunks that are too small cause context fragmentation; fixed-window, sentence-level, and semantic-boundary recursive chunking each involve trade-offs in different scenarios, with no universally optimal solution.75% similarUnverified描述越短、关键词越精准，路由决策往往越准，上下文成本也越低73% similarUnverifiedModels with longer context windows perform better on refactoring tasks spanning multiple files, while models with smaller context windows tend to produce incoherent suggestions due to information truncation.72% similar
