# ChatGPT Solves 50-Year-Old Math Conjecture AI proves its capability by solving a long-standing mathematical problem. - **Source:** [Scientific American Content: Global](https://brifing.si/source/4f066134-e06d-4415-87ef-305e3dc2aba6) - **Published:** 2026-07-14 - **Topic:** [Data & AI](https://brifing.si/c/data-ai) - **Original article:** - **On Brifing:** https://brifing.si/s/20139946-aa66-4c0f-ab18-a102dbe3d6d7 ## AI Revolutionizes Mathematics OpenAI's new language model GPT-5.6 Sol has solved a math problem unsolved for 50 years. The 'cycle double cover conjecture' proof showcases AI's reasoning abilities. Princeton mathematician Noga Alon states this breakthrough will fundamentally change mathematical research. ## Graph Theory and Real-World Applications The solved problem relates to graph theory—structures of dots and lines with applications in real-world networks like the internet. Since the 1970s, mathematicians hypothesized most graphs have a 'cycle double cover' property. AI has now provided a general proof for this conjecture. ## AI's Unique Solution Approach The AI's solution didn't require novel ideas but combined existing human methods more effectively. MIT's Andrew Sutherland notes AI often finds 'easy' solutions to problems perceived as 'hard,' potentially revolutionizing mathematical research by uncovering overlooked pathways. ## The Role of Prompt Engineering OpenAI shared the prompt that led to the successful proof. It included instructions ensuring the AI dedicated effort—like working for at least 8 hours before considering quitting. This prevented the AI from dismissing the problem due to past human failures. ## Collaboration with Multiple AI Agents The solution involved 64 AI agents working in parallel, communicating to avoid false proofs and hallucinations. This multi-agent approach highlights AI's potential in solving complex mathematical problems reliably and efficiently. ## A New Era in Mathematical Research This achievement marks the dawn of AI-driven mathematical discovery. By solving problems humans couldn't, AI is reshaping scientific exploration. Companies like OpenAI continue to enhance AI's reasoning, paving the way for future breakthroughs across disciplines. ## Sources covering this story - https://www.scientificamerican.com/article/chatgpt-just-proved-another-50-year-old-math-conjecture/ — --- _Summary written by Brifing from the original reporting.
