# `Gemma 2 Baku 2B Instruct (rinna/gemma-2-baku-2b-it)` |

|
|
|
# Overview |
|
|
|
The model is an instruction-tuned variant of [rinna/gemma-2-baku-2b](https://huggingface.co/rinna/gemma-2-baku-2b), utilizing Chat Vector and Odds Ratio Preference Optimization (ORPO) for fine-tuning. It adheres to the gemma-2 chat format. |

|
* **Model architecture** |
|
|
|
A 26-layer, 2304-hidden-size transformer-based language model. Please refer to the [Gemma 2 Model Card](https://www.kaggle.com/models/google/gemma-2/) for detailed information on the model's architecture. |
|
|
|
* **Training** |
|
|
|
**Model merging.** The base model was endowed with instruction-following capabilities through a chat vector addition process. The chat vector was derived by subtracting the parameter vectors of [google/gemma-2-2b](https://huggingface.co/google/gemma-2-2b) from [google/gemma-2-2b-it](https://huggingface.co/google/gemma-2-2b-it), as follows. |

~~~~text |
|
rinna/gemma-2-baku-2b + 1.0 * (google/gemma-2-2b-it - google/gemma-2-2b) |
|
~~~~ |
|
|
|
During this process, the embedding layer was excluded during the subtraction and addition of parameter vectors. |
|
|
|
**ORPO** was applied using a subset of the following dataset to further refine the performance of the merged model. |

# How to use the model |
|
|
|
~~~~python |
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
import torch |
|
|
|
model_id = "rinna/gemma-2-baku-2b-it" |
|
dtype = torch.bfloat16 |
|
|
|
tokenizer = AutoTokenizer.from_pretrained(model_id) |
|
model = AutoModelForCausalLM.from_pretrained( |
|
model_id, |
|
device_map="cuda", |
|
torch_dtype=dtype, |
|
attn_implementation="eager", |
|
) |
|
|
|
chat = [ |
|
{ "role": "user", "content": "西田幾多郎とはどんな人物ですか？" }, |
|
] |
|
prompt = tokenizer.apply_chat_template(chat, 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=512, |
|
) |
|
|
|
response = tokenizer.decode(outputs[0][input_ids.shape[-1]:], skip_special_tokens=True) |
|
print(response) |
|
~~~~ |
|
|
|
It is recommended to use eager attention when conducting batch inference under bfloat16 precision. |
|
Currently, Gemma 2 yields NaN values for input sequences with padding when the default attention mechanism (torch.scaled_dot_product_attention) is employed in conjunction with bfloat16. |

|
# Tokenization |
|
The model uses the original [google/gemma-2-2b-it](https://huggingface.co/google/gemma-2-2b-it) tokenizer. |
