Gemma 2 Baku 2B (rinna/gemma-2-baku-2b)
Overview
We conduct continual pre-training of google/gemma-2-2b on 80B tokens from a mixture of Japanese and English datasets. The continual pre-training improves the model's performance on Japanese tasks.
The name baku comes from the Japanese word 獏/ばく/Baku, which is a kind of Japanese mythical creature (妖怪/ようかい/Youkai).

Library
The model was trained using code based on Lightning-AI/litgpt.

Model architecture
A 26-layer, 2304-hidden-size transformer-based language model. Please refer to the Gemma 2 Model Card for detailed information on the model's architecture.
-
Training
The model was initialized with the google/gemma-2-2b model and continually trained on around 80B tokens from a mixture of the following corpora
- Japanese CC-100
- Japanese C4
- Japanese OSCAR
- The Pile
- Wikipedia
- rinna curated Japanese dataset

Benchmarking
Please refer to rinna's LM benchmark page (Sheet 20241003).
How to use the model
import transformers
import torch
model_id = "rinna/gemma-2-baku-2b"
pipeline = transformers.pipeline(
"text-generation",
model=model_id,
model_kwargs={"torch_dtype": torch.bfloat16, "attn_implementation": "eager"},
device_map="auto"
)
output = pipeline(
"西田幾多郎は、",
max_new_tokens=256,
do_sample=True
)
print(output[0]["generated_text"])
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 tokenizer.
