**Cortiq Coder 12B** is a task-specialized coding model compiled from [Qwen3-27B](https://huggingface.co/Qwen/Qwen3-27B) down to ~12B effective parameters using a proprietary dynamic neural network compression method developed by [AllAIGate](https://allaigate.com).
The compression is performed via the **CORTIQ** method — a system and method for **Dynamic Task-Guided Neural Network Compression with Catastrophic Forgetting Prevention**, covered under **US Patent Application No. 19/452,464** (filed January 19, 2026).
Unlike naive pruning or quantization, CORTIQ preserves task-critical knowledge during compression by dynamically guiding the pruning process toward the target domain (code generation), while actively preventing degradation of the model's core reasoning capabilities.
## Key Features
- 🔧 **Optimized for code generation** — structured compression guided by coding tasks
- 🧠 **Based on Qwen3-27B** — retains strong reasoning foundation of the 27B base model at 12B scale
- 🚀 **GGUF Q4_K_M quantization** — ready for efficient local inference
- 🛡️ **Catastrophic forgetting prevention** — task-specific compression without degrading general capabilities
- 📦 **Compact footprint** — 9.37 GB in GGUF Q4_K_M format
