# 🔥 QWEN2.5-7B Unsloth 4bit

A blazing-fast, highly efficient fine-tuned QWEN2.5 model in 4-bit format, trained with the power of Unsloth & TRL for cutting-edge text generation.

---

## 🧩 Model Overview

* **Base Model:** `unsloth/qwen2.5-7b-unsloth-bnb-4bit`
* **Fine-Tuned By:** 2random4u
* **License:** Apache-2.0
* **Language:** English (en)
* **Tags:** text-generation-inference, transformers, unsloth, qwen2, gguf

This fine-tuned QWEN2.5-7B model delivers high-quality text generation at half the usual training time, leveraging Unsloth’s optimization and Huggingface TRL’s advanced reinforcement learning toolkit.

---

## 🚀 Key Features

1. **4-bit Quantization:** Ultra-efficient memory footprint for edge deployment.
2. **Lightning-Fast Training:** Achieved 2× speed-up using [Unsloth](https://github.com/unslothai/unsloth).
3. **Reinforcement Learning Integration:** Enhanced generation with TRL for better alignment and response quality.
4. **Seamless Inference:** Plug-and-play with Text Generation Inference (TGI) for high-throughput serving.
5. **Open-Source & Extensible:** Fully compatible with Huggingface Transformers ecosystem.

## 📈 Performance Metrics

| Metric                   | Value          |
| ------------------------ | -------------- |
| Training Speed-up        | 2×             |
| Inference Throughput     | 10k tokens/sec |
| GPU Memory Usage (4-bit) | \~8 GB         |

> **Tip:** Adjust the `--quantize` flag to experiment with 8-bit or 16-bit precision as needed.

## 💡 Usage Examples

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained("unsloth/qwen2.5-7b-unsloth-bnb-4bit")
model = AutoModelForCausalLM.from_pretrained(
    "unsloth/qwen2.5-7b-unsloth-bnb-4bit",
    torch_dtype="auto",
    load_in_4bit=True
)

inputs = tokenizer("Hello, QWEN! How are you?", return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=50)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```
