## Introduction
**LongCat-Image-Dev** is a development variant of LongCat-Image, representing a mid-training checkpoint that is released to facilitate downstream development by the community, such as secondary fine-tuning via SFT, LoRA, and other customization methods.
### Key Features
- 🔧 **True Developer-Ready Foundation**: Unlike typical release-the-final-model-only approaches, we provide the Dev—a high-plasticity, unconstrained state that avoids RL-induced rigidity. This enables seamless fine-tuning without fighting against over-aligned parameter spaces.
- 🛠️ **Full-Stack Training Framework**: We ship production-ready code for **SFT**, **LoRA fine-tuning**, **DPO/GRPO/MPO alignment**, and **specialized Edit training**. Every stage from pre-training data curation to reward model integration is reproducible, empowering researchers to build on our exact pipeline rather than reverse-engineering it.
