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

Overview

ikedachin/Qwen3.5-27B-imabari-v1 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_v1.

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_v1
  • 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_v1
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

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_name = "ikedachin/Qwen3.5-27B-imabari-v1"

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
