Libraries

How to use AdarshSingh7647/HETU-Qwen3-4B-MathReasoning-CotGen with Transformers:

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

pipe = pipeline("text-generation", model="AdarshSingh7647/HETU-Qwen3-4B-MathReasoning-CotGen")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("AdarshSingh7647/HETU-Qwen3-4B-MathReasoning-CotGen")
model = AutoModelForCausalLM.from_pretrained("AdarshSingh7647/HETU-Qwen3-4B-MathReasoning-CotGen", device_map="auto")
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]:]))

HETU-Qwen3-4B-MathReasoning-CotGen

Part of the HETU (Hints Enable True Understanding) model suite.

Base model: Qwen/Qwen3-4B
Task: math reasoning (AIME, GSM8K, MATH-500, Omni-MATH, GPQA-Diamond, MMLU)
Method: trained to generate a full chain-of-thought before producing its output (CotGen)

This is the full merged model (base weights + LoRA adapter merged in), final training checkpoint, in bf16.

See the HETU paper for the training setup, evaluation methodology, and results tables.
