# **Supertron1-4B: A Capable, Efficient Instruction-Tuned Language Model**

## **Model Description**

**Supertron1-4B** is an instruction-tuned language model built on top of Qwen3-4B. Designed to be a **reliable, efficient daily driver**, it delivers strong performance across math, coding, reasoning, and general conversation while remaining fast and lightweight enough to run on consumer hardware.

* **Developed by:** Surpem
* **Model type:** Causal Language Model
* **Architecture:** Dense Transformer, 4B parameters
* **Fine-tuned from:** [Qwen/Qwen3-4B](https://huggingface.co/Qwen/Qwen3-4B)
* **License:** Apache 2.0

## **Results**

Supertron1-4B holds its own against models in the 4–8B class and surpasses Mistral 7B on all four core benchmarks despite having nearly half the parameters.

</div>

**Key takeaways:**
- Beats Mistral 7B on every benchmark at 4B parameters
- Strong GSM8K and HumanEval performance from math and coding focused tuning
- Competitive with Phi-4 mini on a fraction of the compute

## **Get Started**

```python
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_id = "surpem/supertron1-4b"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)

messages = [
    {"role": "user", "content": "Explain the difference between LoRA and full fine-tuning."}
]

text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to(model.device)

outputs = model.generate(**inputs, max_new_tokens=512)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:], skip_special_tokens=True))
```
