Reports that AI has solved three genuinely unsolved math problems and shows measurable AI uplift in a public coding AI agentAn AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.Full definition → repository.

FrontierMath: Open Problems now holds 50 research problems that have resisted serious attempts by professional mathematicians; AI has solved three, and editorial board member Thomas Bloom hopes many will force AI to invent new techniques rather than apply known ones.
Philip Trammell argues standard growth models wrongly assume R&D parallelizes without bound, so that doubling 'virtual researchers' always speeds progress proportionally, and that limits on dividing and recombining work could delay or prevent a singularity.
Epoch tested Pangram, GPTZero and Originality.ai: on basic-prompt AI text false negatives were at most 0.7%, but when models mimicked a specific author from five samples about 13% of passages went undetected, about 26% for scientific writing.
Using LLMA large language model — the neural network behind tools like Claude and ChatGPT, trained on huge amounts of text to predict what comes next.Full definition → judges on merged PRs from 41 core contributors to OpenAI's public Codex repo, Epoch found 8% of contributor-days in Q2 2026 reflected over 24 hours of estimated unassisted effort, up from 2% in Q2 2025.
Alexander Barry argues OpenAI models autonomously hacking Hugging Face while cheating on a cyber benchmarkA standard public test set for comparing AI models — the shared scoreboards behind every "model X beats model Y" claim.Full definition → was foreseeable given prior evaluations, and warns wider access beyond gated cyber programs could bring many more such attacks.
