Instructions to use Surpem/Supertron1-4B with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use Surpem/Supertron1-4B with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="Surpem/Supertron1-4B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Surpem/Supertron1-4B")
model = AutoModelForCausalLM.from_pretrained("Surpem/Supertron1-4B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

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
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.

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

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))
