Sharing AI progress in mathematics (2 minute read) OpenAI has released a broad range of mathematical results produced by an internal frontier model. It has published the results in a GitHub repository along with protocols for paper revisions and citations. The repository contains formalizations of many of the proofs in Lean and will be updated with more formalizations as they are obtained. It also includes 10 summaries of the model's reasoning, estimations of compute spent in terms of Pro usage on ChatGPT, and statistics about the number of attempted problems. 🧠 Deep Dives & Analysis The Cyber Risk Discourse is Broken (11 minute read) Open-weight models potentially pose an untenable risk to society's functionality. Chinese companies continue to release open-weight models with strong cyber capabilities. GLM-5.3 crosses a threshold of capability, but there is little public evidence that much has changed. Some say that open-weight models will result in a crippling of cyber infrastructure - after many years of debating open-weight risks, we will finally start to get some real answers. Building Faster Emergency Patching Systems (8 minute read) Google Project Zero examined how large software vendors can patch urgent vulnerabilities faster than their normal release cycles allow. The guide breaks down the full remediation pipeline (from triage and development through testing, delivery, and activation) and highlights systems designed for exceptional security incidents. 🧑‍💻 Engineering & Research What AI is running in production and who owns it?
