Frontier AI Models Solve Long-Standing Math and Communication Puzzles

Recently, undisclosed internal models from OpenAI (including Astra, GPT-5.6, and Claude Fable) have demonstrated astonishing problem-solving capabilities in basic science, consecutively cracking multiple long-standing problems in mathematics and theoretical computer science, drawing immense attention from the academic community.

Confirmed

• Ten Major Problems Solved: According to Scott Aaronson and others, OpenAI's internal models have solved ten major open problems, covering geometry, coding theory, quantum complexity, and the "unit distance" conjecture proposed by Paul Erdős in 1946.
• Communication Mystery Solved: Frontier LLMs (such as GPT-5.6 and Claude Fable) successfully resolved the MIMO detection problem that has plagued the wireless communication field for 25 years since 2000. This involves finding a polynomial-time algorithm for perfect transmission in an N×N Gaussian channel when the signal-to-noise ratio is at least 2 log N.
• High Academic Praise: Mathematicians like Terence Tao have validated the AI's proofs, considering them completely correct and on par with top-tier papers published in Inventiones or STOC.

Unconfirmed

• Results Under Review: Although the AI-generated proofs are fundamentally considered entirely correct, these breakthrough findings are currently still in the internal review stage and have not yet undergone formal peer review.
• Model Versions in Doubt: The specific details and capability boundaries of the models mentioned in the posts, such as GPT-5.6, Claude Fable, and Astra, remain unclear; some may be codenames or internal test versions.

Why It Matters

This series of breakthroughs signifies that large language models are no longer confined to knowledge retrieval. Instead, they are demonstrating a substantive ability to navigate high-dimensional knowledge spaces and tackle bottlenecks in frontier scientific research. AI is becoming a powerful tool for basic theoretical research and is poised to significantly accelerate the development of mathematics and theoretical computer science.
