+# Intro
+
+Yi-1.5 is an upgraded version of Yi. It is continuously pre-trained on Yi with a high-quality corpus of 500B tokens and fine-tuned on 3M diverse fine-tuning samples. 
+
+Compared with Yi, Yi-1.5 achieves stronger performance in coding, math, reasoning, and instruction following, while still maintaining excellent capabilities in language understanding, commonsense reasoning, and reading comprehension.
