Xiaohongshu's AI model dots-note-3.0 has become the first artificial intelligence system to achieve a perfect score at the International Mathematical Olympiad (IMO), solving all six problems for a maximum 42 points2.

The result was recorded at this year's IMO, which concluded in Shanghai on Monday. The achievement was also reported by Chinese state media as a record-setting performance3.

The dots-note-3.0 model is described as the lightest variant in Xiaohongshu's dots3 family, which includes two larger versions — jazz and aria — tailored for different use cases. The note variant is still in beta phase.

A separate Chinese-language report noted that the solution to Question 3 drew particular attention, with the IMO winner describing it as elegant1.

ANALYSIS A perfect 42-point score at the IMO — a competition whose problems are designed to challenge the world's top young mathematicians — represents a concrete, externally validated benchmark for mathematical reasoning in large language models.

Xiaohongshu is primarily known as a social media platform, making its emergence as a competitive AI research lab a notable development in the landscape of Chinese AI model builders.
