GPT-NeoX-Japanese

Overview

We introduce GPT-NeoX-Japanese, which is an autoregressive language model for Japanese, trained on top of https://github.com/EleutherAI/gpt-neox. Japanese is a unique language with its large vocabulary and a combination of hiragana, katakana, and kanji writing scripts. To address this distinct structure of the Japanese language, we use a special sub-word tokenizer. We are very grateful to tanreinama for open-sourcing this incredibly helpful tokenizer. Following the recommendations from Google's research on PaLM, we have removed bias parameters from transformer blocks, achieving better model performance. Please refer this article in detail.

Development of the model was led by Shinya Otani, Takayoshi Makabe, Anuj Arora, and Kyo Hattori from ABEJA, Inc.. For more information on this model-building activity, please refer here (ja).

Usage example

The generate() method can be used to generate text using GPT NeoX Japanese model.

>>> from transformers import GPTNeoXJapaneseForCausalLM, GPTNeoXJapaneseTokenizer

>>> model = GPTNeoXJapaneseForCausalLM.from_pretrained("abeja/gpt-neox-japanese-2.7b")
>>> tokenizer = GPTNeoXJapaneseTokenizer.from_pretrained("abeja/gpt-neox-japanese-2.7b")

>>> prompt = "人とAIが協調するためには、"

>>> input_ids = tokenizer(prompt, return_tensors="pt").input_ids

>>> gen_tokens = model.generate(
...     input_ids,
...     do_sample=True,
...     temperature=0.9,
...     max_length=100,
... )
>>> gen_text = tokenizer.batch_decode(gen_tokens, skip_special_tokens=True)[0]

>>> print(gen_text)
人とAIが協調するためには、AIと人が共存し、AIを正しく理解する必要があります。
