On the Effectiveness of Context Compression for Repository-Level Tasks: An Empirical Investigation

Jia Feng, Zhanyue Qin, Cuiyun Gao +4

Repository-level code intelligence tasks require large language models (LLMs) to process long, multi-file contexts. Such inputs introduce three challenges: crucial context can be o…
