# 🧠 Trillion-7B-preview-Ko-Reasoning

> A large-scale Korean reasoning model fine-tuned from **trillionlabs/Trillion-7B-preview**, designed to excel in logical and multi-hop reasoning tasks in Korean.

---

## 📌 Overview

**Trillion-7B-preview-Ko-Reasoning** is a fine-tuned version of [trillionlabs/Trillion-7B-preview](https://huggingface.co/trillionlabs/Trillion-7B-preview), specifically optimized for **logical reasoning in Korean**. This model is part of a broader research initiative to explore:

- The **transition from multilingual reasoning LLMs** to **Korean-specialized reasoning models**
- The enhancement of **non-reasoning Korean language models** into **reasoning-capable variants**
- The development of open-access models that rival proprietary alternatives in complex reasoning tasks

This model was fine-tuned using a large-scale Korean-English instruction dataset containing diverse multi-hop questions, symbolic logic tasks, and human-crafted reasoning steps.

## 🧑‍💻 Usage

Install Transformers >= 4.50:

```bash
pip install -U transformers
```

Basic example:

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "DimensionSTP/Trillion-7B-preview-Ko-Reasoning"

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(model_name)

prompt = "서울과 부산 중 어디가 더 커?"
messages = [
    {"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)

model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=4096
)
generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]

response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
print(response)
```
