OpenAI Hires Transformer Co-Inventor, Trump AI Official Before IPO

OpenAI is close to solving the Hodge Conjecture, a second Millennium Prize Problem, following earlier controversy over its work on the Navier-Stokes problem. The company is deliberating how to announce the solution collaboratively with the math community to avoid repeating a recent public relations incident. The timing of the announcement remains uncertain as OpenAI weighs its approach.

OpenAI has published a framework for tracking, investigating, and disclosing instances of model misalignment, along with six reports documenting unexpected or concerning model behaviors. The framework establishes a systematic approach to identifying and communicating when AI models behave in ways that diverge from intended design. This represents a step toward greater transparency in how AI developers handle safety issues.

OpenAI has introduced AI-powered advertising tools including Sponsored Agents, along with new capabilities for marketers and integrations with HubSpot and Shopify. The announcement signals OpenAI's expansion into the advertising technology space, offering businesses new ways to reach customers through AI-driven experiences. The tools are designed to help marketers leverage AI agents for advertising purposes, with direct connections to major e-commerce and CRM platforms.

OpenAI is in early-stage discussions with investors about a funding round that could value the company at $1.2 trillion or higher. The talks come as OpenAI has delayed its planned initial public offering to next year or later. The valuation would represent a significant increase from the company's previous funding rounds.
