OpenAI solves well-known math problem with AI reasoning, Cohere launches open Command A+
OpenAI has used a general reasoning model to solve the long-standing Erdős unit distance problem in mathematics – a breakthrough validated by prominent mathematicians. Meanwhile, Cohere launched Command A+, an open 218B MoE model with 25B active parameters that supports 48 languages and can run on minimal hardware.
WHY IT MATTERS
The solution demonstrates that AI models can now contribute to fundamental research and open mathematics, not just application questions. Cohere's model makes powerful AI accessible to more people by requiring less infrastructure, though it falls short of Claude 4.5 Haiku in performance.
