Mathematician Tristan Buckmaster claims that OpenAI learned about his work on the Navier-Stokes equations, which he was working on with Levent Alpöge from Anthropic. According to Buckmaster, OpenAI then used an internal model to solve the equations. This feat has been compared to IBM's Deep Blue computer beating Garry Kasparov in a chess competition in 1997, as reported by Scientific American.

OpenAI has recently announced a new model, GPT-6 Astra, which some consider to be a significant step towards artificial general intelligence. This development has raised concerns about cybersecurity and tech regulation.

OpenAI and Anthropic, both of which are reportedly planning initial public offerings, are seeking investment-grade credit ratings. This would allow them to access the corporate bond market and secure cheaper financing for their infrastructure and partners, according to S&P Global Ratings and the Financial Times.
