- GPT-5.2 conjectures, and an OpenAI model proves, that 'single-minus' gluon tree amplitudes are nonzero ★★★
A preprint by Guevara, Lupsasca, Skinner, Strominger and OpenAI's Kevin Weil showed that tree-level single-minus gluon amplitudes, long assumed to vanish, are nonzero in a 'half-collinear' region of (2,2)-signature kinematics. GPT-5.2 Pro conjectured the general formula from the n=3–6 cases, and…
- OpenAI publishes 'Early science acceleration experiments with GPT-5', including four new math results ★★★
On 20 Nov 2025 OpenAI and academic co-authors, including Timothy Gowers, released case studies of GPT-5 contributing to research in maths, physics, astronomy, computer science, biology and materials science. The paper includes four new mathematical results checked by the human authors. It frames…
- OpenAI researchers claim GPT-5 'solved' 10 Erdős problems; the solutions were already in the literature ★★★
In mid-October 2025 OpenAI's Kevin Weil tweeted that GPT-5 'found solutions to 10 (!) previously unsolved Erdős problems'. Thomas Bloom, who runs erdosproblems.com, called this 'a dramatic misrepresentation': GPT-5 had found existing papers solving problems listed as open only because he did not…
