AI Breakthroughs and Major Events: December 11, 2025
In a landmark achievement, Nous Research has open-sourced Nomos-1, a 30B parameter reasoning system that scored an impressive 87 out of 120 on the 2025 Putnam Contest—one of the most prestigious and challenging math competitions in the world. This score would have placed it second among nearly 4,000 human participants, marking a major leap in AI’s ability to tackle complex, creative, and abstract problems. Nomos-1 uses a two-phase approach, with AI “workers” solving and critiquing problems, then a tournament bracket selecting the best answers.
The open-sourced reasoning harness demonstrates that gains are due to model training, not just orchestration, showing that AI is now capable of not just processing data but engaging in genuine reasoning and problem-solving. This breakthrough signals that AI is poised to become an indispensable tool in scientific research, education, and innovation.
