SWE-Fixer: Training Open-Source LLMs for Effective and Efficient GitHub Issue Resolution

SWE-Fixer is a simple yet effective solution for addressing real-world GitHub issues by training open-source LLMs. It features a streamlined retrieve-then-edit pipeline with two core components: a code file retriever and a code editor.

This repo holds the SWE-Fixer-Retriever-7B model, which is finetuned on the Qwen2.5-7B.
