Last month we launched Project Glasswing, our collaborative AI cybersecurity initiative. Since then, we and our partners have found more than ten thousand high- or critical-severity vulnerabilities in essential software.

Model S & X changed automotive history forever by proving that an EV could be the best car possible – of any kind. By inspiring other automakers to believe in EVs, they pushed the industry from 50k cars total in 2011 to 21 million sold per year. Many automotive firsts: Model S – first EV to achieve a 400-mile range, first production car to do 0-60 in <2 seconds & first production sedan to run a 9.23 second quarter mile. It was also the first vehicle with a roof so strong that it broke NHTSA's testing machine. Model X – quickest production SUV & the first to not roll over in regulatory tests. Model S & X also initiated real-world AI! We never stopped refining either vehicle. Both have 40% fewer parts today & share only 3% of parts with their original version. 60 years of evolution (by conventional car development standards) squeezed into 14 years! 750,000 Model S & X built. Your support – from our earliest days to now – made Tesla into what it is today. Thank you to each of our owners ❤️

After nearly 18 years I can stop working on Model S and X. We put so much love into these products, but will continue to pour that into the future products. Thanks to everyone who believed in and supported these cars through the years. We strived for the best and will never stop. Saying goodbye to something great and making room for something even greater!

The proof came from a general-purpose reasoning model, not a system built specifically to solve math problems or this problem in particular, and represents an important milestone for the math and AI communities. openai.com/index/model-di…

New on the Science Blog: We gave Claude 99 problems analyzing real biological data and compared its performance against an expert panel. On 23 problems, the experts were stumped. Our most recent models solved roughly 30% of those—and most of the rest.

Three years since the first flight of Starship, the next generation is here. New ship. New booster. New engines. New pad and new test site. SpaceX engineers are working to solve one of the most difficult engineering challenges in history: developing a fully, rapidly reusable rocket
