# 🔥 BLAZE: Cross-Language and Cross-Project Bug Localization

**BLAZE** is a transformer-based bug localization model that works across languages and software projects. It enhances source-bug alignment using **dynamic chunking** and **hard example learning**, enabling precise bug localization in unseen codebases and programming languages.

## ✨ Highlights

* 📌 **Cross-project & cross-language** bug localization with no re-training
* 📏 **Dynamic Chunking** handles long files within LLM context windows
* 🧠 **Hard Example Learning** improves generalization and ranking accuracy
* 🌍 Supports Java, Python, C++, JavaScript, and Go
* 📊 Outperforms both cross-project and embedding-based baselines
