Elon Musk’s AI Is Building a Game You Can Actually Step Into

Unlock over $3M+ in startup perks and discounts on the best products

RocketHub’s Startup Perks Program is designed to help founders save time and money by giving them access to 250+ curated SaaS deals, valued at over $3M. From marketing tools to CRMs, hosting, and more—we’ve negotiated exclusive offers on the platforms startups actually need. These perks are updated regularly, so you’ll always have access to the latest and most useful tools, without the headache of hunting down discounts yourself.

Elon Musk’s xAI is diving into gaming, reportedly hiring Nvidia researchers to build AI world models that can create full 3D game environments. The goal? A playable, AI-generated game before 2026 — and Musk’s even calling it a “great” one. xAI’s new hires, plus a fresh “video games tutor” job listing, show the company’s serious about teaching its AI how to understand physics, design, and player interaction. With world models heating up across the AI scene, Musk clearly wants xAI to lead the charge into truly playable, AI-made worlds.

Andrew Tulloch, who co-founded Mira Murati’s AI startup Thinking Machine Lab, just left to rejoin Meta — a big win for Zuckerberg’s Superintelligence Lab. Tulloch, who previously spent 11 years at Meta and a stint at OpenAI, reportedly got a massive offer worth up to $1.5B over six years (though Meta says that number’s inflated). He helped Murati raise $2B for TML earlier this year, making his exit right after their first product launch pretty surprising. With Meta pouring $72B into infrastructure and reshuffling its AI teams, this hire could signal big moves ahead.

Researchers at Duke University just unveiled TuNa-AI — a platform that mixes robotics and machine learning to design smarter nanoparticles for drug delivery. It tested over 1,200 formulations and boosted success rates by 43% compared to old-school methods. The system even made a tough leukemia drug dissolve better and kill more cancer cells, all while cutting toxic ingredients by 75%. By handling both material choice and mix ratios at once, TuNa outsmarts current tools. In short, it’s a big step toward making once-failed drugs actually work.

Meta is spicing up Facebook Dating with AI, rolling out two new features aimed at killing swipe fatigue. The first is a dating assistant chatbot that uses text prompts to surface better matches and even drop profile tips or date ideas. Instead of sticking to basics like age or education, it digs into unique interests to make things more personal. The second, called Meet Cute, skips swiping altogether by delivering a surprise match each week. It’s Meta’s way of standing out from Tinder and Bumble, though the real test will be making sure AI doesn’t serve up awkward, off-base matches.

OpenAI says it’d totally be down to buy Google Chrome—if the courts ever force Google to sell it. The comment came during a major antitrust trial where the DOJ is trying to break up Google’s dominance in online search. Google’s not having it, insisting Chrome isn’t up for grabs and calling the lawsuit bogus. OpenAI previously tried partnering with Google (no luck), and now it’s riding with Microsoft and Bing. Meanwhile, Google’s flexing Gemini, and OpenAI might even be cooking up its own social network. The AI wars just keep getting juicier.
