OpenAI claimed a math breakthrough this weekend, only to be smacked down

The embarrassing episode sprouted from a misunderstood post, amplified by an OpenAI executive as proof of GPT-5’s mathematical prowess, but turned out not to be what it seemed.

In an embarrassing episode this weekend, OpenAI was forced to walk back a claim of a major math breakthrough. Kevin Weil, OpenAI’s VP of science, posted on X that “GPT-5 just found solutions to 10 (!) previously unsolved Erdős problems, and made progress on 11 others. These have all been open for decades.”

What do you think “found solutions” means? It sure sounds like they are saying GPT-5 solved these problems!

But shortly after posting this, Thomas Bloom, who runs ErdosProblems.com, disputed the claim. Bloom’s website contains a database of 1,103 of Hungarian mathematician Paul Erdős’ challenging problems and references to their solutions that have been found in academic research papers. Bloom called OpenAI’s announcement “a dramatic misrepresentation,” and said that GPT-5 found merely references to solutions for 10 problems that were previously published.

The competition is extremely intense among top AI companies to achieve computing breakthroughs that might indicate the eternally imminent arrival of AGI, so a post like this from such a high-ranking executive caught the industry’s attention.

After being called out for the incorrect claim, Weil acknowledged the error, saying he misunderstood the post in which researcher Mark Sellke detailed the Erdős problems listed as open that GPT-5 had found published solutions for. Weil deleted the original post, but not before other top AI researchers from OpenAI’s rival’s weighed in.

Alphabet’s GoogleMind cofounder and Nobel Prize winner Demis Hassabis wrote, “this is embarrassing.”

EU calls for bids to build “AI gigafactories” in 2026

The European Union wants to shore up its domestic AI infrastructure, and reduce its dependence on American tech companies.

To further this goal, the bloc is planning on accepting bids to build EU-based “AI gigafactories,” according to a report from The Wall Street Journal.

EU Executive Vice-President for Tech Sovereignty, Security and Democracy Henna Virkkunen announced that bids would begin in January or February, according to the report.

As the AI arms race heats up, countries are racing to secure their own sovereign AI infrastructure, including building their own AI models that reflect countries’ culture and language, and control over cloud computing resources.

Europe is lagging behind the US and Asia in AI infrastructure. But it may be hard for the EU to fully break free of American tech — unlike the US and China, there is no European alternative for the powerful GPUs needed to train and run AI models. It’s very likely that any AI gigafactories in the EU will be filled with GPUs from Nvidia.

Google’s AI chip business could be a $900 billion boon for the company

Google may be sitting on a massive new business that it has yet to fully exploit.

Google’s custom tensor processing unit (TPU) AI chips have been getting a lot of attention recently, making the tech world wonder if there are other ways to power its AI dreams rather than just by using Nvidia’s GPUs.

Bloomberg spoke with analysts who estimate that, if it does decide to sell its chips to others, Google could capture 20% of the AI market, making it a $900 billion business. For comparison, Google Cloud pulled in $43.2 billion of revenue last year.

Even if Google just sticks with renting access to its TPUs, it will continue to drive down costs and increase margins as it ekes out performance improvements, such as the 30x improvement in power efficiency that the latest generation of TPUs has delivered for the company.

OpenAI’s Sam Altman has explored bringing his feud with Tesla’s Elon Musk to space

Billionaires, they’re just like us: they want to bring their terrestrial beefs to outer space.

OpenAI CEO Sam Altman has explored buying or partnering with a rocket company to compete with Tesla CEO Elon Musk’s SpaceX, The Wall Street Journal reports. The two billionaires have had numerous public feuds over the years that have played out in the courts and on social media. They also both lead AI companies that have insatiable needs for data centers and have publicly discussed building data centers in space.

Altman seems like he thinks this could be more than science fiction. He reportedly reached out to rocket maker Stoke Space to potentially make equity investments in the company to get a controlling stake, though the talks are no longer active, WSJ reports.

Or perhaps he just wanted a Sherwood bobblehead of himself.

Report: Meta to slash metaverse, VR spending by up to 30%

Four years after changing its name to reflect its focus on the loosely defined “metaverse,” Meta is planning deep cuts to the company’s money-losing virtual reality efforts, according to a report from Bloomberg.

Meta’s Reality Labs division, home to the teams working on metaverse products — which include Quest VR headsets, Horizon Worlds, and its Ray-Ban Meta glasses — has lost about $70 billion since the company started breaking out the unit in 2020.

The company has struggled to get consumers to buy into CEO Mark Zuckerberg’s vision of working and playing in virtual reality worlds, like the company’s Horizon Worlds platform.

Investors seem to love the news of the pivot, as shares shot up as much as 5% in early trading.

Meta’s recent hiring spree of AI superstars from competitors for its Meta Superintelligence Labs shows that the company’s attention is now all in on AI.
