# ikedachin/Qwen3.5-27B-imabari-v2

日本語の説明は下にあります。  
Japanese description is available below.

## Overview

`ikedachin/Qwen3.5-27B-imabari-v2` is a **fully merged model** created by taking **unsloth/Qwen3.5-27B** as the base model and merging a LoRA adapter trained on **ikedachin/JaQuAD_imabari_v2**.

This model was trained on a Japanese question-answering dataset derived from JaQuAD, and is tuned to generate responses that incorporate the **style and linguistic flavor of the Imabari dialect**.

## What This Repository Contains

This repository contains the **merged full model**, not a LoRA adapter.  
Therefore, you do **not** need to load the base model separately at inference time.

- **Base model:** `unsloth/Qwen3.5-27B`
- **License:** Apache-2.0

## Training Data

The following dataset was used for training:

- **Dataset:** `ikedachin/JaQuAD_imabari_v2`
  - Training includes a dataset containing material licensed under **CC BY-SA 3.0**.
  - Review of attribution, source notice, and possible ShareAlike obligations may be required for this dataset.

This dataset is a reconstructed Japanese QA dataset based on JaQuAD contexts.  
It is characterized by generating **questions, reasoning traces, and answers**, with a particular focus on expressing the **reasoning process and final answers in the Imabari dialect**.

## Training Method

This model was created through the following process:

1. Use **unsloth/Qwen3.5-27B** as the base model
2. Perform LoRA fine-tuning using **ikedachin/JaQuAD_imabari_v2**
3. Merge the trained LoRA adapter into the base model
4. Release the merged model

- **Base model:** `Qwen/Qwen3.5-27B`
- **Method:** LoRA fine-tuning + merged model export
- **Libraries:** Unsloth / Transformers / TRL / PEFT

## Training Environment

Training was conducted on a local workstation environment rather than a cloud notebook.

- **Workstation:** Lenovo ThinkStation PGX
- **Frameworks:** PyTorch, TRL, PEFT
- **Optimization library:** Unsloth
## Usage

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

model_name = "ikedachin/Qwen3.5-27B-imabari-v2"

tokenizer = AutoTokenizer.from_pretrained(model_name)

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.float16,
    device_map="auto",
)
```


## Notes

If you redistribute this model, continue training from it, merge it into another model, use it commercially, or publish derivative models, please make sure to review the following:

1. The Apache-2.0 terms of the Qwen3.5 base model  
2. The CC BY-SA 3.0 terms of the dataset used for training  
3. Whether additional obligations apply depending on the form of distribution  
4. Any required attribution, copyright notice, and source notice
