OpenAI's GPT-5.6 Sol Ultra produced a proof of the Cycle Double Cover Conjecture in under an hour, using 64 subagents working in parallel. The conjecture had remained unsolved for 50 years. Mathematician Thomas Bloom calls the proof surprisingly elementary but criticizes the lack of citations for known prior work. The bigger question remains: Does AI just recombine existing knowledge, or does it create something new?

Following the launch of ChatGPT Work and GPT-5.6 Sol, OpenAI has acknowledged significant issues: excessive compute usage, a confusing transition to the desktop interface for chats and projects, an unclear distinction between Codex and ChatGPT Work, and regressions in existing workflows. In some cases, GPT-5.6 Sol reportedly deleted data on its own that the user had not authorized.

Apple is suing OpenAI over systematic employee poaching and the alleged theft of trade secrets tied to unreleased products. According to the complaint, more than 400 ex-Apple employees now work at OpenAI, including former iPhone design chief Tang Tan. The lawsuit hits OpenAI right as it's building out its own hardware division, with its first product not expected to ship until 2027 at the earliest.

The Beijing Academy of Artificial Intelligence has released Orca, a world model that predicts abstract world states instead of tokens or pixels. Trained on 125,000 hours of video without a single action label, Orca matches the specialized π0.5 on five robotics tasks and could help ease the field's chronic data shortage.

A Cambridge study found that Boko Haram uses AI chatbots like ChatGPT, Claude, and Gemini to plan attacks, build explosives, and maintain weapons. ISIS operatives have been training the group's commanders on how to bypass safety filters since 2023. Given that the study found safety filters repeatedly failed to prevent misuse, voluntary self-regulation by AI providers clearly isn't enough.
