An Anthropic researcher who once worked at OpenAI just quit. He's the latest insider warning that the AI race has become dangerously reckless.

OpenAI said Tuesday that one of its unreleased artificial intelligence models had solved a mathematical puzzle that has eluded mathematicians for generations, a claim that also drew a fight with rival researchers over credit.

OpenAI said today that it has found an AI-generated solution to one of the biggest problems in mathematics —a 200-year-old equation that describes the natural behavior of fluids like water and air.

OpenAI's claim that it solved parts of Navier-Stokes equations has quickly stirred controversy.

OpenAI released its Images 2.5 model with boosted capabilities for personalization and stronger editorial control input. Here's my experiment and what it means for work.

Artificial intelligence has solved a major mathematics problem, but credit for the accomplishment is murky.

Anthropic is expected to unveil its IPO prospectus soon, allowing investors to pore over its finances ahead of a listing that could value the five-year-old company at $2tn or more. OpenAI is expected to follow suit with an IPO next year.

The release of GPT-6 Astra from Open AI has led to the familiar hype cycle that accompanies the launch of any AI model: a much-hyped announcement video, a rollout, and a cacophony of hardcore AI tech people rushing to excitedly share how this new model is going to take away jobs with “shocking” advancements they will decry as minor and insignificant by the time the next model rolls around.

Whether those accusations are true or not, the episode may mark a turning point in the history of mathematics. AI models now seem essential for making progress on the field’s most important problems,
