`Qwen2.5 Bakeneko 32B Instruct (rinna/qwen2.5-bakeneko-32b-instruct)`

Overview

This model is an instruction-tuned variant of rinna/qwen2.5-bakeneko-32b, fine-tuned using Chat Vector and Simple Preference Optimization (SimPO). It adheres to the Qwen2.5 chat format and is designed to deliever superior performance in Japanese language tasks.

Model architecture

A 64-layer, 5120-hidden-size transformer-based language model. For a comprehensive understanding of the architecture, please refer to the Qwen2.5 Technical Report.
Training

This model was developed through a multi-stage training process:

Model merging. The base model was augmented with instruction-following capabilities through a Chat Vector addition process. The Chat Vector was derived by subtracting the parameter vectors of Qwen/Qwen2.5-32B-Instruct from Qwen/Qwen2.5-32B, as follows.
```
  rinna/qwen2.5-bakeneko-32b + 1.0 * (Qwen/Qwen2.5-32B-Instruct - Qwen/Qwen2.5-32B)
```
During this process, the embedding layer was omitted when performing the subtraction and addition of parameter vectors.

SimPO was applied using a subset of the following dataset to further refine the performance of the merged model.

How to use the model

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM

model_id = "rinna/qwen2.5-bakeneko-32b-instruct"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    device_map="auto",
    torch_dtype=torch.bfloat16,
)

messages = [
    {"role": "system", "content": "あなたは誠実で優秀な日本人のアシスタントです。"},
    {"role": "user", "content": "ゲーム・小説・アニメに登場するアイテムボックスの特徴と、その原理を詳細に推測してください。"},
]
prompt = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)
input_ids = tokenizer.encode(
    prompt,
    add_special_tokens=False,
    return_tensors="pt"
).to(model.device)

outputs = model.generate(
    input_ids,
    max_new_tokens=1024,
    do_sample=True,
    temperature=0.7,
    top_k=20,
    top_p=0.8,
    repetition_penalty=1.05,
)

response = tokenizer.decode(outputs[0][input_ids.shape[-1]:], skip_special_tokens=True)
print(response)

Tokenization

This model inherits the original Qwen/Qwen2.5-32B-Instruct tokenizer.
