 **The Faro chat model focuses on practicality and long-context modeling. It handles various downstream tasks with higher quality, delivering stable and reliable results even when inputs contain lengthy documents or complex instructions. Faro seamlessly works in both English and Chinese.**
 
-# Faro-Yi-9B
-Faro-Yi-9B is an improved [Yi-9B-200K](https://huggingface.co/01-ai/Yi-9B-200K) with extensive instruction tuning on [Fusang-V1](https://huggingface.co/datasets/wenbopan/Fusang-v1). Compared to Yi-9B-200K, Faro-Yi-9B has gained greater capability in various downstream tasks and long-context modeling thanks to the large-scale synthetic data in Fusang-V1.

-Faro-Yi-9B uses chatml template. This make it easy to set up system prompt and multi-turn conversations.
+Faro-Yi-9B-200K uses chatml template. This make it easy to set up system prompt and multi-turn conversations. It truly excels when used for analyzing long documents or instructions. I recommend using vLLM for long inputs.

-# Aye, matey! The Pythagorean theorem is a nautical rule that helps us find the length of the third side of a triangle. It's like this: if you have a triangle with two sides, you can find the length of the third side by squaring the two sides and then adding them together. The square root of that sum will give you the length of the third side! It's useful for sailing and navigating, so you always know how far you've traveled. Remember, it's all about the sum of squares, me hearties!

 ## Performance
 
 Faro-Yi-9B enhances its ability compared to Yi-9B-200K in most dimensions, especially in long-range modeling and bilingual (English, Chinese) understanding. Faro is competitive among all open-sourced models at around 9B parameters.
