Jason's AI Pair Trade: Short OpenAI. Long Google, xAI, and Anthropic. Why? OpenAI's competition is fierce. " They're facing a Google firing on all cylinders, Anthropic, and Grok beating them in the leaderboards pretty consistently." Polymarket has Google's Gemini 3 at ~87% to finish 2025 as the top-ranked LLM. Over the last six months, Gemini has started to shrink ChatGPT's massive lead in traffic share. Recorded at the @VenetianVegas!

Started baking again. It’s been about a year since I made my last sourdough bread. Let’s see if I still got it. 🍞

Real police officers drive @Tesla police cars for the first time. "I'll even say this in front of their GoPro. I was against these, but now I'm not; It feels like a spaceship!" Vehicles upfitted by @UpfitTesla, a division of @UnpluggedTesla.

💡 Swift Performance Tip Ever used filter(_:) just to grab the first matching element in an array? That’s like running a marathon to reach the first checkpoint. 🏃♂️💨 Instead, use first(where:) It stops searching the moment it finds what you’re looking for. This is both a readability and performance win! Both functions have O(n) complexity in theory, but filter always checks every element in the array — even after it already found a match. first(where:), on the other hand, stops early, often turning a full O(n) scan into a much smaller actual runtime when the condition matches early. #swiftdevelopment #iosdevelopment #swiftui #swiftlanguage

A few years ago you’d only see this in Mexico once in a while at charging spots. Now it’s a regular sighting at random parking areas. #TeslaMexico

Most people don’t know that Tesla has had an advanced AI chip and board engineering team for many years. That team has already designed and deployed several million AI chips in our cars and data centers. These chips are what enable Tesla to be the leader in real-world AI. The current version in cars is AI4, we are close to taping out AI5 and are starting work on AI6. Our goal is to bring a new AI chip design to volume production every 12 months. We expect to build chips at higher volumes ultimately than all other AI chips combined. Read that sentence again, as I’m not kidding. These chips will profoundly change the world in positive ways, saving millions of lives due to safer driving and providing advanced medical care to all people via Optimus. Send an email with three bullet points describing evidence of your exceptional ability to AI_Chips@Tesla.com. We are particularly interested in applying cutting edge AI to chip design. Thanks, Elon

Looks like there are still places in the world where people have never seen a Tesla in their life. Huge hype at new Tesla store in Bogota with people waiting hours in line to sit in one or get a test drive. #Tesla #Bogota #Colombia $TeslaStore
