Model Card for Breeze-7B-Instruct-v0.1
Breeze-7B is a language model family that builds on top of Mistral-7B. By additionally pretraining Mistral 7B with 250GB of Traditional Chinese content, Breeze is specifically intended for Traditional Chinese use.
Breeze-7B-Base is the base model for the Breeze series. It is suitable for use if you have substantial fine-tuning data to tune it for your specific use case.
Breeze-7B-Instruct derives from the base model Breeze-7B-Base and has undergone supervised fine-tuning with over 1 million instances, making the resulting model amenable to be used as-is for commonly seen tasks.
Breeze-7B-Instruct-64k is a slightly modified version of Breeze-7B-Instruct to enable a 64k-token context length. Roughly speaking, that is equivalent to 88k Traditional Chinese characters.
The current release version of Breeze is v0.1.
Practicality-wise:
- Breeze expands the original vocabulary with additional 30,000 Traditional Chinese tokens. With the expanded vocabulary, everything else being equal, Breeze operates at twice the inference speed for Traditional Chinese to Mistral-7B and Llama 7B. [See Inference Performance.]
- Breeze-Instruct can be used as is for common tasks such as Q&A, RAG, multi-round chat, and summarization.
- In particular, Breeze-Instruct-64k can perform tasks at a document level, not a chapter level.
Performance-wise:
- Breeze demonstrates impressive performance in benchmarks for Traditional Chinese, when compared to similar sized open-source contemporaries such as Taiwan-LLM, QWen, and Yi. [See Chat Model Performance.]
- Breeze shows comparable results to Mistral-7B-Instruct-v0.1 on the MMLU and MT-Bench benchmarks. [See Chat Model Performance.]

Inference Performance
In this test, we use the first 700 characters of the web article as the input and ask the model to write the same article again.
All inferences run on 2 RTX A6000 GPUs (using vllm, with a tensor-parallel size of 2).

Use in Transformers
First install direct dependencies:
pip install transformers torch accelerate
If you want faster inference using flash-attention2, you need to install these dependencies:
pip install packaging ninja
pip install flash-attn
Then load the model in transformers:
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
model = AutoModelForCausalLM.from_pretrained(
model="MediaTek-Research/Breeze-7B-Instruct-v0.1",
device_map="auto",
torch_dtype=torch.bfloat16,
use_flash_attn_2=True # optional
)
The structure of the query template follows that of Mistral-7B-Instruct, as shown below.
<s> SYS_PROMPT [INST] QUERY1 [/INST] RESPONSE1 [INST] QUERY2 [/INST]
where SYS_PROMPT, QUERY1, RESPONSE1, and QUERY2 can be provided by the user.
The suggested default SYS_PROMPT is
You are a helpful AI assistant built by MediaTek Research. The user you are helping speaks Traditional Chinese and comes from Taiwan.
