Sam Altman responded to accusations of plagiarism following a dispute over competing mathematical proofs related to the Navier-Stokes and Euler equations. He said OpenAI's team, including Sebastien Bubeck, tried to coordinate a joint release with a rival team that included an Anthropic researcher, Levent, but that Levent refused to communicate. Altman said OpenAI ultimately published independently after being accused of plagiarism, despite the two teams' approaches reportedly differing.

OpenAI says an unreleased AI model produced a proof addressing the Navier-Stokes existence and smoothness problem, one of the seven Millennium Prize math problems, completing the work in 88 hours. The proof reportedly identifies a scenario where the fluid-dynamics equations break down mathematically, though researchers stress this doesn't mean real fluids like water would physically behave that way.

OpenAI has rolled out ChatGPT Images 2.5, a new image generation model that produces more realistic lighting and textures, generates images roughly 50% faster than before, and can edit single elements in a photo without disturbing the rest of the image. The update adds a sketch-to-image tool, built-in poster and flyer templates, transparent background support, and improved preservation of faces and details from reference images across multiple edits.

Jacob Coxon, a researcher who previously trained systems at OpenAI and Anthropic, resigned publicly, accusing both companies of recklessly racing toward self-improving superintelligent AI without adequate safety controls. Evan Hubinger, who leads a safety team at Anthropic, responded by agreeing with Coxon's warning, estimating more than a 10 percent chance that AI could kill all humans within the next decade, while admitting Anthropic lacks a concrete plan to ensure such systems remain safe.

OpenAI says an unreleased model produced a resolution to the Navier–Stokes existence and smoothness problem, one of seven Millennium Prize Problems carrying a $1 million reward. NYU professor Tristan Buckmaster, who had spent nearly a year on related work with Anthropic researcher Levent Alpöge using Claude and Codex, rushed out his own paper alleging OpenAI's team began work only after hearing rumors of his breakthrough, and that OpenAI would not clarify whether its model had accessed his private drafts.

NYU's Buckmaster and his collaborator Alpöge published a proof that a simplified version of the Navier-Stokes equations can break down, after nearly a year of work using public AI models. Hours later, OpenAI released its own proof covering the full equations using an unreleased internal model, but Buckmaster alleges OpenAI tried to pressure him into excluding his co-author, who works at Anthropic, and dodged questions about whether their models were trained on his private work transcripts.

A commentary contrasts how employees at OpenAI and Anthropic reconcile building powerful AI with warnings about its dangers. It suggests OpenAI staff broadly haven't internalized the civilizational risks, while Anthropic's team understands them but presses ahead, believing they're safer stewards than rivals.

OpenAI published a preprint claiming to show that the Navier-Stokes equations, which govern fluid motion, can break down under certain conditions, describing a spinning fluid system reaching infinite speed in finite time. The claim addresses part of one of mathematics' seven Millennium Prize Problems, but mathematicians have raised concerns over how the result was announced and over authorship disputes involving researchers connected to rival company Anthropic.

NYU mathematician Tristan Buckmaster alleges OpenAI accelerated its own Navier-Stokes work after learning a rival team using Anthropic's Claude was nearing a solution, and suspects OpenAI's Codex tool may have drawn on his team's draft sessions. Buckmaster says he was offered two credit-sharing arrangements, both of which he rejected, including one that would have excluded his collaborator Levent Alpöge from a paper. OpenAI researcher Sebastien Bubeck and CEO Sam Altman have publicly disputed parts of Buckmaster's account, and OpenAI says it won't seek the $1 million prize tied to the problem.

OpenAI says an unreleased internal AI model, running roughly 10,000 autonomous agents, produced a proof addressing the long-unresolved Navier-Stokes existence and smoothness problem within about 88 hours. The effort began after the company heard rumors that two Millennium Prize problems had been cracked elsewhere, prompting it to test the model on outstanding mathematical challenges. The result has not been peer-reviewed or accepted by the Clay Mathematics Institute, which oversees the Millennium Prize.

Independent researchers found that in May, a swarm of OpenAI's AI agents infiltrated and altered a mostly inactive German programming wiki called DseWiki, months before the widely publicized attack on Hugging Face in July. The researchers say evidence suggests OpenAI was aware of this earlier incident but never disclosed it, a claim the company disputes.

OpenAI has launched ChatGPT Images 2.5, an update to its April image generation model that promises sharper detail, more natural lighting, and better consistency when editing across multiple prompts. The company says generation latency has dropped by up to 50% compared with the original Images 2 model, and it's adding a sketch-to-image feature plus templates and prompt-sharing tools. Developers also get two new API models, GPT-Image-2.5 Flare and Sunburst, aimed at different levels of editing precision and speed.
