What's going on with OpenAI and the Navier-Stokes controversy?

OpenAI announced a solution to the Navier-Stokes Millennium Prize Problem, but the claim is disputed because the work may have relied on unpublished research from other parties. Mathematician Tristan Buckmaster alleges that OpenAI used drafts from his Codex sessions and offered him credit options that he rejected. OpenAI stated it will not pursue the $1 million prize for the solution.
