Mathletic competition in AI just got hotter. A new open-source AI model for advanced mathematics has emerged, offering high performance with remarkably low training costs. This development represents a significant step in democratizing powerful AI tools, as it provides enterprises and researchers with a freely available, high-performing model that can be modified or deployed for commercial use without restrictions.
The big picture: Researchers have released Light-R1-32B, an open-source 32-billion parameter AI model specifically optimized for solving complex mathematics problems, available on Hugging Face under the permissive Apache 2.0 license.
Performance breakthrough: The new model outperforms similarly sized and even larger open-source alternatives on challenging mathematical benchmarks.
- Light-R1-32B achieved scores of 76.6 on AIME24 and 64.6 on AIME25, surpassing the performance of DeepSeek-R1-Distill-Qwen-32B and DeepSeek-R1-Distill-Llama-70B.
- The American Invitational Mathematics Examination (AIME) contains 15 advanced math problems that human students are given 3 hours to solve.
Cost efficiency: The team completed the model’s training in under six hours using just 12 Nvidia H800 GPUs, with a total estimated cost of only $1,000.
- This represents one of the most economical approaches for developing high-performing specialized AI models.
- The rapid training time demonstrates the potential for more accessible AI development in specialized domains.
Technical foundation: Light-R1-32B builds upon Alibaba‘s open-source Qwen 2.5-32B-Instruct model.
- The researchers have also released their training datasets, scripts, and evaluation tools alongside the model.
- Despite its mathematics specialization, the model maintains strong generalization abilities on scientific reasoning tasks.
Why this matters: The permissive Apache 2.0 license allows organizations to use, modify, and commercialize the model without restrictions, potentially accelerating innovation in AI-powered mathematics and scientific applications.

DOE fusion roadmap targets 2030s commercial deployment as AI drives $9B investment
The Department of Energy has released a new roadmap targeting commercial-scale fusion power deployment by the mid-2030s, though the plan lacks specific funding commitments and relies on scientific breakthroughs that have eluded researchers for decades. The strategy emphasizes public-private partnerships and positions AI as both a research tool and motivation for developing fusion energy to meet data centers' growing electricity demands. The big picture: The DOE's roadmap aims to "deliver the public infrastructure that supports the fusion private sector scale up in the 2030s," but acknowledges it cannot commit to specific funding levels and remains subject to Congressional appropriations.
