Llama 3 has exhibited excellent performance on many English language benchmarks. However, it also seemingly been finetuned on mostly English data, meaning that it will respond in English, even if prompted in other languages.

We have fine-tuned Llama 3 on almost 90,000 multilingual conversations meaning that this model has the smarts of Llama 3 but has the added ability to chat in more languages.

Please feel free to comment on this model and give us feedback in the Community tab!

We will release a paper in the future describing how we made the training data, the model, and the evaluations we have conducted of it.

How to use

The easiest way to use this model on your own computer is to use the GGUF version of this model (lightblue/suzume-llama-3-8B-multilingual-gguf) using a program such as jan.ai or LM Studio.

If you want to use this model directly in Python, we recommend using vLLM for the fastest inference speeds.

python

from vllm import LLM, SamplingParams

sampling_params = SamplingParams(temperature=0.0, max_tokens=100)
llm = LLM(model="lightblue/suzume-llama-3-8B-multilingual")

messages = []
messages.append({"role": "user", "content": "Bonjour!"})
prompt = llm.llm_engine.tokenizer.tokenizer.apply_chat_template(conversation=messages, add_generation_prompt=True, tokenize=False)
prompts = [prompt]

outputs = llm.generate(prompts, sampling_params)
for output in outputs:
    prompt = output.prompt
    generated_text = output.outputs[0].text
    print(f"Prompt: {prompt!r}, Generated text: {generated_text!r}")

Evaluation scores

We achieve the following MT-Bench scores across 6 languages:

	meta-llama/Meta-Llama-3-8B-Instruct	lightblue/suzume-llama-3-8B-multilingual	Nexusflow/Starling-LM-7B-beta	gpt-3.5-turbo
German 🇩🇪	NaN	7.26	6.99	7.68
French 🇫🇷	NaN	7.66	7.29	7.74
Japanese 🇯🇵	NaN	6.56	6.22	7.84
Russian 🇷🇺 *	NaN	8.19	8.28	7.94
Chinese 🇨🇳	NaN	7.11	6.97	7.55
English 🇺🇸	7.98	7.73	7.92	8.26

* (Note the Russian scores exclude code, reasoning and math problems due to not having any translated reference answers for these questions.)

We observe minimal degredation of Llama 3's English ability while achieving best-in-class multilingual abilities compared to the top rated 7B model (Nexusflow/Starling-LM-7B-beta) on the Chatbot Arena Leaderboard.

Here is our evaluation script.

Training data

We train on three sources of data to create this model:

lightblue/tagengo-gpt4 - 76,338 conversations
- A diverse dataset of initial inputs sampled from lmsys/lmsys-chat-1m and then used to prompt gpt-4-0125-preview
megagonlabs/instruction_ja - 669 conversations
- A hand-edited dataset of nearly 700 Japanese conversations taken originally from translations of the kunishou/hh-rlhf-49k-ja dataset.
openchat/openchat_sharegpt4_dataset - 6,206 conversations
- Multilingual conversations of humans talking to GPT-4.

We prepare our data like so:

python

import pandas as pd
from datasets import Dataset, load_dataset, concatenate_datasets

### Tagengo
gpt4_dataset = load_dataset("lightblue/tagengo-gpt4", split="train")
gpt4_dataset = gpt4_dataset.filter(lambda x: x["response"][1] == "stop")
####

### Megagon
megagon_df = pd.read_json(
    "https://raw.githubusercontent.com/megagonlabs/instruction_ja/main/data/data.jsonl",
    lines=True,
    orient="records"
    )
role_map = {"user": "human", "agent": "gpt"}
megagon_df["conversations"] = megagon_df.utterances.apply(lambda x: [{"from": role_map[y["name"]], "value": y["text"]} for y in x])
megagon_df["language"] = "Japanese"
megagon_df = megagon_df[["conversations", "language"]]
megagon_dataset = Dataset.from_pandas(df)
###

### Openchat
openchat_df = pd.read_json("https://huggingface.co/datasets/openchat/openchat_sharegpt4_dataset/resolve/main/sharegpt_gpt4.json?download=true")
openchat_df["conversations"] = openchat_df["items"]
openchat_dataset = Dataset.from_pandas(openchat_df)
###


dataset = concatenate_datasets([gpt4_dataset, megagon_dataset, openchat_dataset])
dataset = dataset.filter(lambda x: not any([y["value"] is None for y in x["conversations"]]))
dataset.select_columns(["conversations"]).to_json("/workspace/llm_training/axolotl/llama3-multilingual/tagengo_openchat_megagon.json")

This model is a fine-tuned version of meta-llama/Meta-Llama-3-8B-Instruct on the above described dataset. It achieves the following results on the evaluation set:

from fastchat.conversation import Conversation

    Conversation(
        name="llama-3",
        system_template="<|begin_of_text|><|start_header_id|>system<|end_header_id|>\n\n{system_message}",
