Decades-Long Challenge in Convex Optimization Resolved by AI
Convex optimization is a core area of mathematical programming, essential for designing algorithms in machine learning, finance, and engineering. Since the 1990s, a particular class of problems within this domain has remained unsolved, often requiring complex, manual proofs. Traditional methods relied heavily on human ingenuity, with only incremental progress over the years. Recent advances in AI, especially large language models, have primarily been applied to natural language processing and pattern recognition. However, in 2026, OpenAI’s GPT-5.6 demonstrated that with the right prompt, such models can engage in high-level mathematical reasoning, leading to the first solution of this longstanding problem. This marks a turning point in the application of AI to theoretical mathematics, expanding its potential beyond data-driven tasks.
“The successful application of GPT-5.6 to such a complex problem is unprecedented. It indicates that AI can contribute meaningfully to fields traditionally dominated by human experts.”

Unresolved Questions About the Scope and Reliability of AI Solutions
While the solution has been independently verified, it remains unclear how broadly this approach can be applied to other complex mathematical problems. The long-term reliability of AI-generated proofs and solutions, especially in formal scientific contexts, is still under investigation. Additionally, the extent to which GPT-5.6’s reasoning mimics human logic or introduces novel insights is not yet fully understood. Researchers caution that further testing and peer review are necessary to establish the method’s robustness and generalizability.
