Swallow-MS-7b-v0.1

このモデルはtokyotech-llm/Swallow-MS-7b-instruct-v0.1のtokenizer.chat_templateを以下に変更したものです。

tokenizer.chat_template = """{% if messages[0]['role'] == 'system' %}
{% set loop_messages = messages[1:] %}
{% set system_message = messages[0]['content'] %}
{% elif false == true and not '<<SYS>>' in messages[0]['content'] %}
{% set loop_messages = messages %}
{% set system_message = 'あなたは誠実で優秀な日本人のアシスタントです。' %}
{% else %}
{% set loop_messages = messages %}
{% set system_message = false %}
{% endif %}
{% if not (messages[0]['role'] == 'assistant' and loop_messages|length > 0) %}
{{ bos_token }}
{% endif %}
{% for message in loop_messages %}
{% if (message['role'] == 'user') != ((loop.index0 + (1 if messages[0]['role'] == 'assistant' else 0)) % 2 == 0) %}
{{ raise_exception('Conversation roles must alternate starting from the first role.') }}
{% endif %}
{% if loop.index0 == 0 and system_message != false %}
{% set content = '<<SYS>>\n' + system_message + '\n<</SYS>>\n\n' + message['content'] %}
{% else %}
{% set content = message['content'] %}
{% endif %}
{% if message['role'] == 'user' %}
{{ '[INST] ' + content.strip() + ' [/INST] ' }}
{% elif message['role'] == 'system' %}

{% elif message['role'] == 'assistant' %}
{{ ''  + content.strip() + '' + eos_token }}
{% endif %}
{% endfor %}"""

Our Swallow-MS-7b-v0.1 model has undergone continual pre-training from the Mistral-7B-v0.1, primarily with the addition of Japanese language data.

Model Release Updates

We are excited to share the release schedule for our latest models:

• April 26, 2024: Released the Swallow-MS-7b-instruct-v0.1
• March 11, 2024: Released the Swallow-MS-7b-v0.1

This repository provides large language models developed by TokyoTech-LLM.

Model Details

• Model type: Please refer to Mistral technical report for details on the model architecture.
• Language(s): Japanese English
• Tokenizer: This model employs a tokenizer that features a broadened vocabulary based on Japanese data. This allows for a more efficient representation of text using fewer tokens, leading to a notably faster inference process.

Evaluation Benchmarks

MT-Bench JA

We used Japanese MT-Bench to assess the instruction-following capabilities of models. We utilized the following settings:

• Implemantation: FastChat [Zheng+, 2023] (commit #e86e70d0)
• Question: Nejumi LLM-Leaderboard NEO, mtbench_ja_question_v3
• Reference Answer: Nejumi LLM-Leaderboard NEO, mtbench_ja_referenceanswer_v1
• Prompt for Judge: Nejumi LLM-Lederboard NEO, mtbench_ja_prompt_v1
• Judge: gpt-4-1106-preview
• Scoring: Absolute scale normalized to a 0-1 range, averaged over five runs.

Usage

First install additional dependencies in requirements.txt:

pip install -r requirements.txt

Instruction format Ver0.1

This format must be adhered to strictly, as deviations may result in less optimal outputs from the model.

The template used to construct a prompt for the Instruct model is specified as follows:

<s>[INST] <<SYS>>\n{SYSTEM_PROMPT}\n<</SYS>>\n\n{USER_MESSAGE_1} [/INST] {BOT_MESSAGE_1} </s>[INST] {USER_MESSAGE_2}[/INST] 

Please be aware that <s> and </s> are special tokens used for the beginning of string (BOS) and end of string (EOS), respectively, while [INST] and [/INST] are considered regular strings.

For the "{SYSTEM_PROMPT}" part, We recommend using "あなたは誠実で優秀な日本人のアシスタントです。"

For the "{USER_MESSAGE_1}" part, We recommend using {instruction}\n{input}

In other words, We recommend the following:

<s>[INST] <<SYS>>\nあなたは誠実で優秀な日本人のアシスタントです。\n<</SYS>>\n\n{instruction1}\n{input1} [/INST] {BOT_MESSAGE_1}</s>[INST] \n\n{instruction2}\n{input2} [/INST] 

Use the instruct model Ver0.1

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM

model_name = "tokyotech-llm/Swallow-MS-7b-instruct-v0.1"
model = AutoModelForCausalLM.from_pretrained(model_name, torch_dtype=torch.bfloat16, device_map="auto")
tokenizer = AutoTokenizer.from_pretrained(model_name)

device = "cuda"

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": "東京工業大学の主なキャンパスについて教えてください"}
]

encodeds = tokenizer.apply_chat_template(messages, return_tensors="pt")

model_inputs = encodeds.to(device)
model.to(device)

generated_ids = model.generate(model_inputs, max_new_tokens=128, do_sample=True)
decoded = tokenizer.batch_decode(generated_ids)
print(decoded[0])

Training Datasets

Instruction Tuning Ver0.1

The following datasets were used for the instruction tuning.

• OpenAssistant Conversations Dataset was used, where human utterances are included but the responses are not used. Instead, the responses were generated using the Mixtral-8x7B-Instruct-v0.1 model.
• OpenAssistant Conversations Dataset 21k Ja
• OpenAssistant Conversations Dataset 21k En
• Databricks Dolly 15k Ja
• Databricks Dolly 15k En

Please note that some of the data had issues with quality or format, so not all of it was used.

Risks and Limitations

The models released here are still in the early stages of our research and development and have not been tuned to ensure outputs align with human intent and safety considerations.
