Xiaohongshu’s dots-note-3.0 scores a perfect IMO gold
According to the official IMO evaluation, Xiaohongshu’s dots-note-3.0 solved all six problems and became the first Chinese model to receive an official IMO gold-level certification, and the second model in the world to do so after Google Gemini.
- The model achieved 42/42, a perfect score.
- It reportedly solved the problems using natural language end to end, from reading the prompt to writing the proof.
- Judges said some of its solutions were elegant and even used nonstandard but correct proof strategies.
- The article argues that IMO is a stronger test than ordinary benchmarks because the problems are new, hidden before the contest, and graded under the real competition rules.
- The model used an agentic setup with natural language plus Python execution and self-critique.
The result is being framed as a major signal that Xiaohongshu has real foundation-model capabilities, and the model is expected to be open-sourced soon.
