Japanese Gpt Neox 3.6b Instruction Sft

🚀 japanese-gpt-neox-3.6b-instruction-sft

This repository offers a Japanese GPT - NeoX model with 3.6 billion parameters, fine - tuned for instruction - following conversations.

🚀 Quick Start

This repository provides a Japanese GPT - NeoX model of 3.6 billion parameters. The model is based on rinna/japanese-gpt-neox-3.6b and has been finetuned to serve as an instruction - following conversational agent.

✨ Features

Model architecture

A 36 - layer, 2816 - hidden - size transformer - based language model.

Finetuning

The finetuning data is the subset of the following datasets and has been translated into Japanese:

• Anthropic HH RLHF data
• FLAN Instruction Tuning data
• Stanford Human Preferences Dataset

The data will not be released.

💻 Usage Examples

I/O Format

A special format has been adopted to construct inputs:

• An input prompt is formatted as a conversation between ユーザー and システム.
• Each input utterance consists of (1) its speaker ("ユーザー" or "システム"), (2) a colon (":"), (3) a whitespace (" "), and (4) utterance text (e.g. "世界で一番高い山は？").
• The input prompt should be ended with "システム: " to acknowledge the model to generate a response.
• Since the model's tokenizer does not recognize "\n", a special newline symbol "<NL>" is used instead.
• All the newlines in input and output utterances should be replaced with "<NL>".
• All the utterances in the input prompt should be separated by "<NL>".

Basic Usage

prompt = [
    {
        "speaker": "ユーザー",
        "text": "日本のおすすめの観光地を教えてください。"
    },
    {
        "speaker": "システム",
        "text": "どの地域の観光地が知りたいですか？"
    },
    {
        "speaker": "ユーザー",
        "text": "渋谷の観光地を教えてください。"
    }
]
prompt = [
    f"{uttr['speaker']}: {uttr['text']}"
    for uttr in prompt
]
prompt = "<NL>".join(prompt)
prompt = (
    prompt
    + "<NL>"
    + "システム: "
)
print(prompt)
# "ユーザー: 日本のおすすめの観光地を教えてください。<NL>システム: どの地域の観光地が知りたいですか？<NL>ユーザー: 渋谷の観光地を教えてください。<NL>システム: "

How to use the model

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("rinna/japanese-gpt-neox-3.6b-instruction-sft", use_fast=False)
model = AutoModelForCausalLM.from_pretrained("rinna/japanese-gpt-neox-3.6b-instruction-sft")

if torch.cuda.is_available():
    model = model.to("cuda")

token_ids = tokenizer.encode(prompt, add_special_tokens=False, return_tensors="pt")

with torch.no_grad():
    output_ids = model.generate(
        token_ids.to(model.device),
        do_sample=True,
        max_new_tokens=128,
        temperature=0.7,
        pad_token_id=tokenizer.pad_token_id,
        bos_token_id=tokenizer.bos_token_id,
        eos_token_id=tokenizer.eos_token_id
    )

output = tokenizer.decode(output_ids.tolist()[0][token_ids.size(1):])
output = output.replace("<NL>", "\n")
print(output)
"""分かりました。いくつかのおすすめを紹介します。
1. ハチ公像です。ハチ公像は、日本の観光スポットの1つとして人気があります。
2. スクランブル交差点です。多くの人々が行き交う大きな交差点で、観光客に人気のスポットです。
3. 109です。109は、ショッピングやエンターテイメント施設です。
4. 道玄坂です。道玄坂は、日本の商業地区である坂道です。</s>"""

📚 Documentation

Tokenization

The model uses a sentencepiece - based tokenizer:

• The tokenizer has a vocabulary size of 32,000.
• It uses sentencepiece's byte fallback feature to decompose unknown text pieces into UTF - 8 byte pieces and to avoid producing <UNK> tokens.
• sentencepiece's --add_dummy_prefix option was turned off so that a leading whitespace will not be prepended automatically.

print(tokenizer.tokenize("吾輩は猫である"))
# ['吾', '輩', 'は', '猫', 'である']
# instead of ['▁', '吾', '輩', 'は', '猫', 'である'] as in rinna/japanese-gpt-1b

• sentencepiece's --remove_extra_whitespaces option was turned off so that leading, trailing, and duplicate whitespaces are reserved.

print(tokenizer.tokenize("  吾輩は  猫である   "))
# ['▁', '▁', '吾', '輩', 'は', '▁', '▁', '猫', 'である', '▁', '▁', '▁']
# instead of ['▁', '吾', '輩', 'は', '▁猫', 'である'] as in rinna/japanese-gpt-1b

• Don't forget to set use_fast=False to make the above features function correctly.

good_tokenizer = AutoTokenizer.from_pretrained("rinna/japanese-gpt-neox-3.6b", use_fast=False)
bad_tokenizer = AutoTokenizer.from_pretrained("rinna/japanese-gpt-neox-3.6b")

print(good_tokenizer.decode(good_tokenizer.encode("გამარჯობა  吾輩は  猫である   ")))
# 'გამარჯობა  吾輩は  猫である   </s>'
print(bad_tokenizer.decode(bad_tokenizer.encode("გამარჯობა  吾輩は  猫である   ")))
# 'გამარ[UNK]ობა 吾輩は 猫である </s>'
