In mid-May, OpenAI revealed that one of its internal AI models had disproved the Erdős unit distance conjecture, a longstanding problem in discrete geometry that had resisted human mathematicians for eight decades. The company provided early access to the result to several mathematicians and published their reactions online.

Tim Gowers, a recipient of the Fields Medal—mathematics' highest honor—stated that "there is no doubt that the solution to the unit-distance problem is a milestone in AI mathematics." University of Toronto professor Daniel Litt remarked that "this is the first example of a result produced autonomously by an AI that I find exciting in itself, as opposed to as a leading indicator."

The Erdős unit distance conjecture, posed by mathematician Paul Erdős in 1946, asks for the maximum number of pairs of points in a set of n points in the plane that can be exactly one unit apart. The conjecture proposed an upper bound, but the AI model found a counterexample that disproved it.

OpenAI did not disclose the specific architecture or training details of the model, but described it as a general-purpose reasoning system. The model generated the counterexample through a combination of symbolic reasoning and search, without human guidance on the problem.

The achievement marks a significant advance in AI's ability to tackle open mathematical problems. Previous AI systems have assisted in proving theorems or verifying proofs, but this is one of the first instances of an AI autonomously producing a novel result that experts find genuinely surprising.

Mathematicians who reviewed the solution confirmed its correctness. The counterexample has been formally verified, and the result is expected to be published in a peer-reviewed mathematics journal.

OpenAI plans to release further technical details about the model and the solution in a forthcoming paper. The company also intends to make the model available to researchers for exploring other open problems.

The Erdős unit distance conjecture is now resolved, with the AI's counterexample showing that the maximum number of unit distances grows faster than the conjectured bound. This result closes a chapter in discrete geometry that began nearly a century ago.

OpenAI announced the expansion of its Codex Computer Use feature to Windows users. The capability, previously available on macOS, now allows Windows PC owners to control their machines remotely through the ChatGPT mobile application. This development marks a significant step in integrating AI-powered automation into everyday computing tasks.

The Computer Use feature leverages Codex, OpenAI's AI system that translates natural language into executable commands. Users can instruct ChatGPT to perform actions such as opening applications, navigating files, or adjusting system settings. The system interprets the request and executes the corresponding operations on the Windows machine.

To use the feature, Windows users must install a companion application on their PC and link it to their ChatGPT account. Once connected, commands issued via the ChatGPT mobile app are relayed to the desktop client, which carries out the actions. The setup process requires enabling remote access permissions and ensuring both devices are on the same network.

OpenAI emphasized that the feature is designed for convenience and productivity. Common use cases include automating repetitive tasks, managing files while away from the desk, or assisting less tech-savvy users with system configurations. The company also highlighted security measures, such as requiring explicit user confirmation for sensitive operations.

The rollout follows months of testing on macOS, where the feature received positive feedback for its reliability and ease of use. Windows support addresses a major demand from users who rely on the platform for work or personal computing. OpenAI plans to continue refining the tool based on user feedback.

Availability begins immediately for ChatGPT Plus and Pro subscribers. The companion app is downloadable from OpenAI's official website and supports Windows 10 and 11. Users must have an active internet connection and a ChatGPT account with an active subscription to access the feature.

Pricing remains unchanged: ChatGPT Plus costs $20 per month, while Pro is $200 per month. The Computer Use feature is included at no additional cost for these tiers. OpenAI noted that free-tier users cannot access the functionality at this time.

OpenAI stated that the Computer Use feature for Windows is now live and ready for use. The company encourages users to explore the capabilities and provide feedback for future improvements.

Apple is developing a significant overhaul of its Siri assistant, incorporating advanced artificial intelligence capabilities.
