Model Card for Breeze-7B-Base-v1_0
Breeze-7B is a language model family that builds on top of Mistral-7B, specifically intended for Traditional Chinese use.
Breeze-7B-Base is the base model for the Breeze-7B 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, making the resulting model amenable to be used as-is for commonly seen tasks.
The current release version of Breeze-7B is v1.0.
Practicality-wise:
- Breeze-7B-Base expands the original vocabulary with an additional 30,000 Traditional Chinese tokens. With the expanded vocabulary, and everything else being equal, Breeze-7B operates at twice the inference speed for Traditional Chinese to Mistral-7B and Llama 7B. [See Inference Performance.]
- Breeze-7B-Instruct can be used as is for common tasks such as Q&A, RAG, multi-round chat, and summarization.
Performance-wise:
- Breeze-7B-Instruct demonstrates impressive performance in benchmarks for Traditional Chinese and English when compared to similar-sized open-source contemporaries such as Taiwan-LLM-7B/13B-chat, QWen-7B-Chat, and Yi-6B-Chat. [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
# Instruction Model
model = AutoModelForCausalLM.from_pretrained(
"MediaTek-Research/Breeze-7B-Instruct-v0_1",
device_map="auto",
torch_dtype=torch.bfloat16,
attn_implementation="flash_attention_2" # optional
)
# Basemodel
model = AutoModelForCausalLM.from_pretrained(
"MediaTek-Research/Breeze-7B-Base-v0_1",
device_map="auto",
torch_dtype=torch.bfloat16,
attn_implementation="flash_attention_2" # optional
)
For Breeze-7B-Instruct, the structure of the query is
<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.
We also integrate chat_template into tokenizer_config.json, so you can apply_chat_template to get the prompt.
>>> from transformers import AutoTokenizer
>>> tokenizer = AutoTokenizer.from_pretrained("MediaTek-Research/Breeze-7B-Instruct-v0.1")
>>> chat = [
... {"role": "user", "content": "你好，請問你可以完成什麼任務？"},
... {"role": "assistant", "content": "你好，我可以幫助您解決各種問題、提供資訊和協助您完成許多不同的任務。例如：回答技術問題、提供建議、翻譯文字、尋找資料或協助您安排行程等。請告訴我如何能幫助您。"},
... {"role": "user", "content": "太棒了！"},
... ]
>>> tokenizer.apply_chat_template(chat, tokenize=False)
"<s>You are a helpful AI assistant built by MediaTek Research. The user you are helping speaks Traditional Chinese and comes from Taiwan. [INST] 你好，請問你可以完成什麼任務？ [/INST] 你好，我可以幫助您解決各種問題、提供資訊和協助您完成許多不同的任務。例如：回答技術問題、提供建議、翻譯文字、尋找資料或協助您安排行程等。請告訴我如何能幫助您。 [INST] 太棒了！ [/INST] "
