🚀 Chitti

Enterprise coding assistant for secure software development and cybersecurity research.

---

Overview

Chitti is a fine-tuned 7B coding assistant designed for professional developers, security researchers, and software engineering teams.

Built upon Qwen2.5-Coder-7B-Instruct, Chitti combines abliteration and LoRA fine-tuning to improve coding performance while remaining practical for legitimate cybersecurity and software engineering workflows.

The complete training, evaluation, and deployment pipeline was developed independently using MoLab (Marimo).
