# REx86: A Local Large Language Model for Assisting in x86 Assembly Reverse Engineering

> The paper fine-tunes eight local models from CodeLlama, Qwen2.5-Coder, and CodeGemma on 5,981 x86 assembly examples and evaluates their help with binary reverse engineering.

## Scope and limitations

Evaluation covers a curated x86 assembly dataset and a 43-person user case study of line-level understanding and problem solving.

## Why it fits this collection

It studies local language-model assistance for understanding and commenting on x86 disassembly used in binary reverse engineering.

## Publication and review notes

The DOI comes from the arXiv record, and the venue and date from Crossref.
