## 🎯 What Is This?

Qwen3.6-27B fine-tuned on ~14k Claude 4.6 Opus reasoning traces. The model adopts a structured, efficient thinking style — concise on simple tasks, deep on hard ones — while fully preserving the base model's exceptional coding and math capabilities.

**Key improvement over base Qwen3.6-27B:** reduced verbose reasoning loops, replaced with Claude-style structured step-by-step decomposition.

## 🧠 Example Output Style

The model always reasons before answering:

```
<think>
Let me analyze this request carefully:

1. Identify the core objective...
2. Break the task into subcomponents...
3. Evaluate constraints and edge cases...
4. Formulate a step-by-step solution...
</think>
