OpenAI's Internal Models Crack Multiple Math Problems, Earning Academic Recognition

Recently, OpenAI's unreleased models (including Astra, GPT-5.6, and Claude Fable) have demonstrated remarkable problem-solving abilities in fundamental sciences, solving multiple long-standing open problems in mathematics and theoretical computer science, drawing significant academic attention.

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, group theory, circuit complexity, quantum complexity (e.g., parallel repetition of quantum games), and Paul Erdős's 1946 "unit distance" conjecture. Quanta Magazine also published an in-depth article on why AI is cracking this legendary math problem.
• Communications puzzle solved: Frontier models (e.g., GPT-5.6 and Claude Fable) have solved the MIMO detection problem that has plagued wireless communications for 25 years since 2000. The problem asks for 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. According to Dimitris Papailiopoulos and others, the proof is lengthy but based on elementary theory.
• High academic praise: Mathematicians such as Terence Tao have affirmed the correctness of the AI proofs, deeming them worthy of top journals like Inventiones or STOC best paper, but noted a lack of underlying theoretical novelty.

Unconfirmed

• Results under review: Although the AI proofs are considered fundamentally correct, these breakthroughs are still under internal review and have not undergone formal peer review.
• Model versions uncertain: Details and capabilities of models like GPT-5.6, Claude Fable, and Astra are unclear; some may be codenames or internal test versions.

Why it matters

This series of breakthroughs marks a shift for large language models from mere knowledge retrieval to demonstrating substantive ability in navigating high-dimensional knowledge spaces and solving frontier research bottlenecks. AI is becoming a powerful tool for fundamental theoretical research, potentially accelerating progress in mathematics and theoretical computer science.
