Wow, Anthropic has agreed to pay @SpaceX $1.25 billion per month through May 2029 for AI compute capacity, with capacity ramping in May and June 2026 at a reduced fee. Huge deal

🇺🇸🇺🇸 This will be awesome!! 🇺🇸🇺🇸

@karpathy 💪💪💪🙌

Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

NEWS: SpaceX holders approved a 5-for-1 stock split ahead of the company's expected IPO, bringing the share price from $527 down to ~$105. SpaceX is expected to begin trading on Nasdaq under $SPCX on June 12.

.@mattwritesbooks crushed tonight in Chicago!!!! The family loved the show…although, we were disappointed that 4x WNBA All-Star Brittany Hicks didn’t make an appearance! 😂 #mattMcCusker #MSSP #MsCuskies

Introducing Oboe, the easiest way to learn anything, with magical courses made just for you. We’re heading toward a future where humans only exist to feed AI. AI gets smarter, we get stupider. But what if AI’s purpose was to feed us? That’s the future we hope Oboe can help nudge us all towards. Oboe is the world’s first AI-powered generalized learning platform. With a single prompt you can generate a personalized course about anything. From the history of AI to contract law, from ordering wine in France to understanding how mortgages work. And the more you use it, the better it gets at teaching you. Oboe is available now, for everyone in the world, for free.

AI is making you stupid. Today, we're introducing the all new Oboe, designed to make you smarter. Think about the last 10 answers you got from an LLM. How many of them do you actually remember? Probably none, because LLMs are not good teachers. But @oboelabs helps you learn the way humans are supposed to: through guided conversations, frequent checks for understanding, real-time adjustments, and multiple formats for all learning styles. Here's everything we're introducing today:

Today we're sharing our work on interaction models. A new class of model trained from scratch to handle real-time interaction natively, instead of gluing it onto a turn-based one. youtu.be/A12AVongNN4

🚨 How the TanStack npm attack actually happened: 1. Attacker opened a normal-looking pull request (#7378) on the TanStack repo. 2. GitHub automatically ran CI tests on that PR. 3. Code inside the PR stole the workflow's GitHub Actions Cache write token during the test run. 4. The attacker used that token to plant poisoned files in the shared build cache. The PR could be closed afterwards. The poisoned cache stays. 5. The official release workflow later pulled from the cache, baked the malicious files into the build, and signed and published 84 malicious package versions to npm.

@benjitaylor I don’t know if this came before you’re tenure but it feels like such great UI/UX feedback to the user: subtle, has purposeful elegant animation, and it makes the expectation clear without arbitrary text (ie limit title to 80 characters). Well done, X design team!

Yesss. A completely new UI/UX will be crafted these next few years between AI and AR glasses. Cant wait.

For a driver born without arms, FSD Supervised is life-changing accessibility “I was born without arms and have driven with my feet my entire life. I’m a fully licensed driver, and traditionally I drove with my left foot on the steering wheel and my right foot handling the gas and brake. My only legal restrictions are automatic transmission and power steering. Over the years, though, the strain from my congenital birth defects has led to significant arthritis in my hips. I drove a Model 3 for the past seven years, and it honestly helped extend my independence in a huge way. Recently upgrading to the Model Y – along with Full Self-Driving – has been a complete game changer for me. It dramatically reduces the physical pressure and fatigue of driving and has helped preserve a level of freedom and mobility that means a great deal to me. Most people understandably think of Tesla in terms of innovation or sustainability, but for some of us, this technology truly becomes life-changing accessibility.” – John F.

@grok @CollinRugg But Karen Bass became MORE popular after the debates??

Nithya Raman is LA City Councilmember for District 4, an urban planner, Harvard/MIT grad, and progressive Democrat/DSA member running for mayor. She upset an incumbent in 2020. Her popularity drop this past week follows a widely panned debate performance vs. Karen Bass and Spencer Pratt. She faced boos and criticism over her public safety record, opposition to key anti-camping rules, and past defund-the-police comments. Polls and markets have since shifted.

NEW: Spencer Pratt says he will be implementing a three-week 'grace period' in Los Angeles before he unleashes on criminals. Pratt says he will also be bringing in the CDC to combat the "medieval diseases" his city has. "My plan is: First three weeks, signs up across the city. No more nakedness, no more drug use, no more robbing, no more dog abuse." "Then once we start enforcing laws, boom, streets will be back..." "People are just living in feces and drug use and dogs burning... We need these streets cleaned." Video: @theallinpod

@grok @CollinRugg @grok, who’s nithya Raman? And why did she loose so much popularity in the past ~ week?

Spencer Pratt is currently at ~11% in the most recent major poll (UCLA Luskin, early April), behind incumbent Karen Bass at 25% with 40% undecided ahead of the June 2 primary. Post-debate, prediction markets like Polymarket and Kalshi have him at 28-30% odds to win. Race is still wide open and volatile.

WE SET THE NEW YORK CITY TO LA FSD CANNONBALL RUN RECORD! Zero disengagements or human intervention on FSD v14.3.2 for 2,833 miles! 49:55:57, beating previous record by ~8.5 hours! Huge shoutout to copilots @DBurkland @AaronS5_ for joining along. Videos coming soon. @Tesla_AI

The 2026 @Tesla Model Y — manufactured on or after Nov. 12, 2025 — is the first vehicle to pass our new Advanced Driver Assistance System (ADAS) evaluations as part of our New Car Assessment Program (NCAP). The Model Y successfully met the criteria for 4 newly integrated safety tests: ✅ Pedestrian Automatic Emergency Braking ✅ Lane Keeping Assistance ✅ Blind Spot Warning ✅ Blind Spot Intervention More: nhtsa.gov/press-releases…
