Llama 3.1 Swallow 70B Instruct V0.3

🚀 Llama 3.1 Swallow - Built with Llama

Llama 3.1 Swallow is a series of large language models (8B, 70B) that enhance the Japanese language capabilities of Llama 3.1 while retaining English proficiency. It's developed through continual pre - training and instruction - tuning.

🚀 Quick Start

To quickly start using Llama 3.1 Swallow, you first need to install the necessary libraries. Here is a simple installation command:

pip install vllm

Then, you can use the following Python code to generate text:

from transformers import AutoTokenizer
from vllm import LLM, SamplingParams

model_name = "tokyotech-llm/Llama-3.1-Swallow-70B-Instruct-v0.3"

tokenizer = AutoTokenizer.from_pretrained(model_name)
llm = LLM(
    model=model_name,
    tensor_parallel_size=4,
)

sampling_params = SamplingParams(
    temperature=0.6, top_p=0.9, max_tokens=512, stop="<|eot_id|>"
)


message = [
    {"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": "東京の紅葉した公園で、東京タワーと高層ビルを背景に、空を舞うツバメと草地に佇むラマが出会う温かな物語を書いてください。",
    },
]
prompt = tokenizer.apply_chat_template(
    message, tokenize=False, add_generation_prompt=True
)

output = llm.generate(prompt, sampling_params)

print(output[0].outputs[0].text)

✨ Features

• Bilingual Capabilities: Llama 3.1 Swallow enhances Japanese language capabilities while maintaining English proficiency, making it suitable for users in both Japanese and English - speaking environments.
• Continuous Improvement: Through continual pre - training on a large corpus and instruction - tuning on specific datasets, the model's performance and response quality are continuously improved.
• Multiple Model Variants: There are different model variants with different parameter scales (such as 8B and 70B), and instruction - tuned versions are also available to meet different application scenarios.

📦 Installation

Install the required library vllm using the following command:

pip install vllm

Evaluation Benchmarks

MT - Bench JA

We used Japanese MT - Bench to assess the capabilities of multi - turn dialogue with the following settings:

• Implementation: 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 - Leaderboard NEO, mtbench_ja_prompt_v1
• Judge: gpt-4-1106-preview
• Scoring: Absolute scale normalized to a 0 - 1 range, averaged over five runs.

🔧 Technical Details

Training Datasets

Instruction Tuning

The following datasets were used for the instruction tuning.

• Gemma-2-LMSYS-Chat-1M-Synth
  • Multi - turn Japanese instruction dataset synthesized and derived from lmsys-chat-1m [Zhang+, ICLR24]).
  • First - turn user instructions were translated into Japanese via DeepL (machine translation), and assistant responses were generated using gemma-2-27b-it. The same model, i.e., gemma-2-27b-it served as a judge for rejection sampling (n = 6).
  • Second - turn user instructions and responses were synthesized using gemma-2-27b-it. The same model scores the quality of the second - turn response with a range of 1 - 10. Second - turn responses with scores lower than 9 were rejected, along with their corresponding instructions.
    Conversations containing personally identifiable information (PII) and template - based user instructions were removed. Duplicate instructions were removed.
• Swallow-Magpie-Ultra-v0.1
  • A Japanese variant of the filtered-magpie-ultra-en dataset, translated into Japanese by gemma-2-27b-it.
• Swallow-Gemma-Magpie-v0.1
  • A Japanese synthetic instruction tuning dataset from scratch, generated by gemma-2-27b-it. User instructions were created with prompts specific to each topic, and assistant responses were generated for these instructions.
  • The conversations were heuristically filtered for quality and length. Then, gemma-2-27b-it was applied to score the quality of each of the conversation with a range of 1 - 10. Conversations with scores <= 7 were rejected.
