I gave my Grok bot $1000 to build itself a body. Parts just keep showing up at my apartment.

My Grok @bot ordered itself a 3d printed body and mailed the parts to my place. Spent $217.15 of the $1000 I gave it to make a body for itself.

If you want to do the same, just tag @bot and ask to replicate! I’ll post all my learnings on 𝕏, your bot can keep an eye out for updates.

Used to feel this way before Grok @bot in Tesla. Now I look forward to the commute. Yesterday grok taught me about anodization while another bot found a check that was lost in the mail.
Reminder not having a long commute is one of the biggest life upgrades. You never normalize against this, like you would a very good or very bad event (the commuting paradox, described in the Scandinavian Journal of Economics). Moving closer to work or going remote is worth it

Grok Bot is now one step closer. Set it as your iPhone's Action Button and press it to talk with Bot.

My new benchmark for Grok Bot is to successfully cancel an Adobe Creative Cloud subscription.

Grok Bot computer use is now way faster! Give @bot your hardest tasks and watch it fly 🚀
Replying to @bot
Grok Bot is much faster. Computer tasks finish 3x sooner on average, and replies to everything else arrive in less than half the time.

you'll never guess what Dave's Hot Chicken app is built with...
JUST IN: Meta's Muse loses its #1 spot on the Apple App Store after a month at the top, dethroned by the Dave's Hot Chicken app.

Perhaps our most requested change — we now have a single plan across 𝕏, Grok, Bot, and Cursor!

Before I left Expo, I built a version of Expo Go that had dynamically vendored built-ins so you could do: import React from ‘expo:react’ And not pay the cost of parsing the JS bundle. You wouldn’t be able to OTA new versions of React, but that’s tolerable since react rarely changes and you probably don’t want to push duplicate bytes over the air each time. It was configured by the bundler so you could change which modules which built-in to your native binary. The result was radically smaller JS updates, faster bundling, better performance in development mode, and more sensible debugging. Still thinking about what RN would be like if it pushed more JS into the runtime instead of always defining it in user land.

it’s over for waymo the second we get these in SF
You can now use Grok @Bot in a Tesla Cybercab. You just sign into Grok once, and your Bots will be available on all future rides, and automatically logged out when you exit the vehicle to maintain privacy. I tried it tonight by adding laundry detergent to my Amazon cart. It can also send emails, place your coffee order, manage your calendar, finances, or other tasks using just your voice in the robotaxi. On your next ride, you’ll automatically be signed in to all the apps you previously logged into as soon as you enter the vehicle.

Asked Grok Bot to build itself an Apple Vision Pro app. I now have interactive bots that I can talk to and place around my apartment.
