@akshatwts Me atm.

[Cursor @cursor_ai]

We're excited to join forces with @SpaceX to advance the frontier of useful AI. Expect significant improvements to Cursor soon.

Liftoff! First $SPCX trade complete 🚀

[Elon Musk @elonmusk]

I love the incredible people of SpaceX beyond words

.@SpaceX listing day is here. Watch live. $SPCX https://t.co/VTXg0N2TBc

[Elon Musk @elonmusk]

As the recently expanded partnership with @AnthropicAI demonstrates, @SpaceX is offering AI compute as a service at significant scale.

We are in discussions with other companies to do the same.

Over time, especially with orbital data centers, we expect to serve AI at extremely high scale.

@elonmusk @SawyerMerritt @Starlink The last thing you want on a flight is to login through a captive portal and watch an Ad to get free Wifi. Thanks Elon for making this decision!

[xAI @xai]

SpaceXAI will provide @AnthropicAI with access to Colossus 1, one of the world’s largest and fastest-deployed AI supercomputers, to provide additional capacity for Claude → https://t.co/nfDR9S822L

grok 4.3 api is out, try it out!

[Eric Jiang @veggie_eric]

When training Grok 4.3, we spoke directly with devs and businesses to understand what they actually needed: a model that’s fast, affordable, and great at tool calling. The result is a daily driver that doesn't just look good on random benchmarks, but is actually useful in the real world.

💰 $1.25 in / $2.50 out
⚡️ 100 tokens / second
📖 1 million context window

Try it through Hermes Agent or direct through the xAI API!

[SpaceX @SpaceX]

SpaceXAI and @cursor_ai are now working closely together to create the world’s best coding and knowledge work AI.

The combination of Cursor’s leading product and distribution to expert software engineers with SpaceX’s million H100 equivalent Colossus training supercomputer will allow us to build the world’s most useful models.

Cursor has also given SpaceX the right to acquire Cursor later this year for $60 billion or pay $10 billion for our work together.

Happy Easter from the xAI Memphis team!

Wishing everyone a day full of chocolate eggs, good company and maybe a few universe-sized questions. 🐣

Here’s a first look at X-Plane 12 on Apple Vision Pro!

With visionOS 26.4 and NVIDIA CloudXR 6.0, the simulator streams wirelessly at up to 4K/120fps to your headset.

And if you have a physical yoke or throttle, ARKit uses image detection to recognize them and place them inside your virtual cockpit. 🤯 It’ll be available later this spring.

Another one bites the dust

My wife calls me, panicked.

The call is from her number, and her voice is unmistakable- that’s my wife.

‘Babe, our son is hurt. He got in a bike wreck. I’m at the emergency room but they won’t take our insurance and I need cash to get him help. Please send me 3000 dollars as soon as you can, he’s really not doing well.’

Me- ‘Wow, that’s scary. Tell me our passphrase and then I’ll send the money.’

Her (it) - ‘What? What passphrase? This is your wife, our son is hurt. Send the money now!!’

Me- ‘I’ll call you back. I don’t believe that this is my wife. If it is, I’m sorry, but we discussed this.’

The number? Spoofed. Easy to do and there’s no way to tell if a phone number is being spoofed aside from hanging up and calling back to confirm.

The voice? AI generated. Easily done. A few seconds of audio is all it takes to create a realistic audio deepfake.

What can you do?

1) Create a family safe word or passphrase. Ours is definitely not ‘Keep Going’ although we considered it. Discuss the passphrase far away from phones or any recording device. This is as analog as possible. Don’t forget that the trigger for the passphrase is just as important as the phrase itself. So instead of asking ‘what’s the safe word?’ have a separate triggering question. For example, you could say ‘I’m eating banana cream pie’ and this would trigger your spouse to respond ‘purple velvet pillows’ if that’s the safe word.

Make it fun, silly, and easy to remember. And DON’T WRITE IT DOWN.

2) Cognitive security is an essential skill in 2026. Assume every image and video you see online is fake until proven otherwise. Expect scams and spammers, and be pleasantly surprised when it’s not.

3) Figure out a backup communication option with people who you absolutely need to be able to reach. Don’t just rely on a phone number for communication. Have redundant, ideally encrypted methods of communication with family.

What did I miss? I think (hope) Nikita is wrong on the timeframe- agentic bots like Claude bot are impressive but not quite ready to flood the phone lines in just 90 days. But I think it’s going to be a huge problem by the end of the year. I already get dozens of increasingly realistic spam calls and texts daily- it’s only going to get more annoying. Have a plan to keep your family and your finances safe!

@chrisgpt dang even called it "twitter" like they existed then 🤣
