Models & Research

OpenAI Reports AI-Generated Solution to the Navier–Stokes Problem — OpenAI reports that its internal AI system solved a longstanding mathematical problem by showing that smooth fluid motion under a smooth external force can develop infinite velocity in finite time while retaining finite energy. Approximately 10,000 coordinated AI agents helped produce the proof, which was subsequently formalized and verified in Lean. The result highlights AI’s growing potential for mathematical discovery. OpenAI ↗

My takeaway: It's remarkable that AI found a proof in just 88 hours for a problem that had remained unsolved for over 90 years. It will likely help solve many more longstanding problems. I think what matters more now is how well we understand those solutions and use them to develop new mathematics.

GPT-5.6 Sol assists researcher in running quantum experiments — An MIT researcher is using OpenAI's GPT-5.6 Sol with Codex to automate routine quantum computing measurements, including analyzing results and calibrating qubits. OpenAI ↗

My takeaway: Researchers can save time by connecting agents to software-controlled instruments and documenting each task as a skill. the agents can then run well-defined workflows overnight, with researchers checking in occasionally.

Tools & Open Source

How Meta Limits Security Risks in Its Muse AI Agent — Meta describes how Muse uses an isolated computing environment, protected credentials, and an independent permission system called Sentinel to control actions and data sharing. Layered defences and user approvals aim to limit damage from mistakes and prompt injection, which remains an unsolved problem. Meta also outlines plans for a confidential computing option designed to prevent even Meta from accessing users’ stored data. Meta ↗

My takeaway: Muse runs in a dedicated VM, with Sentinel controlling permissions and credentials kept hidden from the model.

Policy & Society

Anthropic warns Claude subscribers about stolen sessions — Several Claude subscribers reported unexplained usage spikes that they attributed to unauthorized account access. Anthropic confirmed compromises to some affected users and issued refunds and warnings in certain cases. Anthropic declined to comment on how users could identify misuse. TechCrunch AI ↗

My takeaway: Treat AI credentials as financial assets, and insist on detailed usage logs and a way to revoke sessions so you can spot and stop unauthorized spending.
