# 🌟 Qwen2.5-Coder-3B — Claude Opus 4.6 Reasoning Distilled

A compact, fast, locally-runnable coding model fine-tuned on top of **Qwen2.5-Coder-3B-Instruct** using high-quality reasoning trajectories distilled from **Claude 4.6 Opus**. Designed to run efficiently on consumer hardware with as little as **4GB VRAM** at ~88 tokens/sec.

---

## 💡 Model Introduction

**Qwen2.5-Coder-3B-Claude-Opus-4.6-Distilled** combines the strong code generation foundation of Qwen2.5-Coder with the structured, step-by-step reasoning style of Claude 4.6 Opus. Through Supervised Fine-Tuning (SFT) with LoRA, the model learns to think through problems carefully inside `<think>` tags before delivering precise, well-structured answers.

Unlike larger distilled models, this 3B model is built for **real local inference** — fast, private, and fits comfortably in 4GB VRAM.

---

## 🧠 Reasoning Style

The model adopts Claude Opus's structured reasoning pattern:

```
<think>
Let me analyze this carefully.

1. Identify the core objective.
2. Break down into subcomponents.
3. Consider edge cases and constraints.
4. Formulate and verify the solution.
</think>

[Final clean answer here]

## ⚡ Hardware Requirements

| Quantization | VRAM | Speed (RTX 3050) |
|---|---|---|
| Q4_K_M (this file) | ~2.1 GB | ~88 t/s |
| Q3_K_M | ~1.7 GB | ~95 t/s |
| Q8_0 | ~3.3 GB | ~70 t/s |

Runs comfortably on **4GB VRAM** laptops and desktops.

## ⚠️ Limitations

- **3B scale** — will struggle with very long multi-file code generation or complex system design
- **1 epoch training** — reasoning style is distilled but not as deep as larger models
- **Hallucination risk** — like all LLMs, may produce incorrect facts; always verify outputs
