TL;DR
GPT-5.6 successfully applied a prompt-based approach to close a 30-year gap in convex optimization. This breakthrough demonstrates AI’s potential in solving longstanding mathematical challenges, with significant implications for optimization theory and practical applications.
GPT-5.6, an advanced AI language model, has used a specific prompt to solve a 30-year-old problem in convex optimization. This development marks a significant milestone in artificial intelligence’s ability to address complex mathematical challenges, with potential impacts across computational mathematics and applied sciences.
The breakthrough was achieved when GPT-5.6 was prompted with a carefully designed query that guided it to develop a novel approach for a problem long considered intractable within the field of convex optimization. Experts say this is the first time an AI model has directly contributed to solving such a foundational issue. The problem, known among mathematicians as the ‘Convex Gap Conjecture,’ has resisted solutions since the early 1990s, impacting areas like operations research, machine learning, and economic modeling. The developers behind GPT-5.6 confirmed that the model’s response involved a new theoretical framework that was previously unformulated, enabling the closure of the gap in understanding. This achievement was verified through peer review and independent testing, which confirmed the solution’s validity and robustness.While the specifics of the prompt and the detailed methodology are proprietary, researchers emphasize that the success hinged on a strategic prompt design that leveraged GPT-5.6’s reasoning capabilities. The approach exemplifies how prompt engineering can unlock AI’s potential in advanced scientific research, beyond traditional data processing or pattern recognition tasks.

Historical Challenges in Convex Optimization
The ‘Convex Gap Conjecture’ has been a central unsolved problem in convex optimization since the early 1990s. It concerns the conditions under which certain convex functions can be optimized efficiently and has implications for the theoretical limits of algorithms used in machine learning and operations research. Over the past three decades, numerous mathematicians have attempted to resolve this problem, but progress was hindered by its inherent complexity and the limitations of existing mathematical tools. The advent of large language models like GPT-5.6, which can process and generate complex reasoning based on prompts, has opened new possibilities for tackling such issues. Prior efforts relied primarily on human-led theoretical approaches, with limited success, until now.
