# OpenAI and Anthropic staff work on Navier-Stokes step

The companies say a solution to the fluid dynamics problem is in progress.

OpenAI stated it has claimed to have solved the Navier-Stokes problem, with mathematician Tristan Buckmaster and a member of Anthropic staff working on a step toward the solution using both Anthropic and OpenAI models [^3].

The claim comes as Jacob Coxon, a former researcher at Anthropic and OpenAI, stated on the platform X that both companies are more focused on outcompeting rivals than ensuring safe development of advanced AI systems [^2].

Samuel Marks, a technical staff member at Anthropic, agreed with Coxon's concerns, noting that it is not always possible to guarantee models act exactly as developers intend [^1].
