MediaTek Research Breeze-7B (hereinafter referred to as 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.
Breeze-7B-32k-Base is extended from the base model with more data, base change, and the disabling of the sliding window. Roughly speaking, that is equivalent to 44k Traditional Chinese characters.
Breeze-7B-32k-Instruct derives from the base model Breeze-7B-32k-Base, making the resulting model amenable to be used as-is for commonly seen tasks.
Practicality-wise: - Breeze-7B-Base expands the original vocabulary with additional 30,000 Traditional Chinese tokens. With the expanded vocabulary, 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. - Breeze-7B-32k-Instruct can perform tasks at a document level (For Chinese, 20 ~ 40 pages).

Long-context Performance
Needle-in-a-haystack Performance
We use the passkey retrieval task to test the model’s ability to attend to different various depths in a given sequence. A key in placed within a long context distracting document for the model to retrieve. The key position is binned into 16 bins, and there are 20 testcases for each bin. Breeze-7B-32k-Base clears the tasks with 90+% accuracy, shown in the figure below.
