ArXiv to Leave Cornell

arXiv.org announced it will leave Cornell University and establish an independent nonprofit to manage the preprint repository. The change is designed to streamline philanthropic funding by removing Cornell as an intermediary and to safeguard the platform from institutional pressure. Since its 1991 launch, arXiv has become the primary communication channel for physics, mathematics, computer science and related fields. The move signals a strategic shift toward greater financial transparency and operational autonomy.

About the OpenAI Amplitudes Paper, but Not as Much as You’d Like

OpenAI partnered with amplitude researchers to use an internal LLM, dubbed GPT‑5.2 Pro, to conjecture and prove a simplified scattering‑amplitude formula (equation 39) in a twelve‑hour run. The accompanying paper and press release provide scant detail on prompts, model outputs, or...

Hypothesis: If AI Is Bad at Originality, It’s a Documentation Problem

OpenAI teamed with particle‑physics amplitudes researchers to apply reasoning‑type language models to a puzzling non‑zero calculation. The AI iteratively generated a compact formula and mathematically proved its correctness, turning a messy multi‑particle result into a simple expression. The breakthrough highlights...
