@fraser_cook @xai All the best on your next adventure and hope you enjoy your break. It has been a pleasure working with you!

Today marks the end of my time at @xai I was incredibly fortunate to have joined at a time where I was able to help take us from nothing to something across a few surfaces. It has been a privilege to work alongside some of the world’s best for almost two years and share in the ups, downs and everything in-between. I wish all of them well, past and present, and want to thank them for what has been a very special period of my life!

1 year at @xai. Time flew. Here’s to Year 2 🥂

Grok 4.3 is now live on the xAI API. It’s our fastest, most intelligent model to date. It tops the @ArtificialAnlys leaderboards in agentic tool calling and instruction following, and ranks #1 in @ValsAI enterprise domains like case law and corporate finance. Grok 4.3 supports a 1 million token context window and is priced at $1.25/m input and $2.50/m output. Create an API key and start building: console.x.ai/team/default/a…

Ooh image editing in-app in cool. Well done @engineering 👏🏽

Anger management in action.

Can’t believe I’ve managed to get tickets to Angine de Poitrine! See you in October ✋🏽🔺🤚🏽

// AGENTS.md Never, ever, under any circumstances, ever, not once, no matter what, try to start the fucking dev server, it’s already fucking running.

>what do you think of the claude codebase? brother, i'm not even reading my own code anymore. what makes you think i'm going to read someone else's?

Grok Imagine multi-image to video and video extension are now available on API. Use up to 7 images to create a video or extend existing videos by 10 seconds. Try it here: x.ai/api/imagine

Dracula with Cynthia Erivo was truly amazing. Even from shitty balcony seats.

@JaimeAlns @xai The absolute goat of the London office. You’ll be missed!

It’s one of those: today was my last day at @xAI. xAI has been a tremendous formative experience for me, building the API, Grok.com, and everything in between, it’s been crazy and hectic, but overall amazing. I’m especially grateful to everyone I’ve worked with, @TobyPhln and the team in London, you’re the most talented team I’ve ever worked with. I’ll be cheering from the sidelines, really excited to see what the xAI team is going to come up with next!

it’s on slack bro. it’s in the drive. i just put it in the notion bro i literally sent it to you on teams. did you check the airtable bro? it’s in the box bro. it’s single sign on, it’s on okta bro. no you need the yubikey. check your deel bro, it’s on gusto. check outlook bro

@TobyPhln @xai @elonmusk I’m sad to see you go but excited to hear what you’ll create next. What you did in London with the products and team is nothing short of amazing. I’m very lucky to be part of that and glad to have worked with you. All the best 🚀

Three years, thousands of PRs, and a million jokes. Today was my last day @xai. To the team: you rock, no one burns the midnight oil better. To @elonmusk, thanks for taking me on board. I've learnt more about execution, speed, and product perfectionism than I could ever have imagined. Thanks for everything. My next priorities: sleep for more than 8h, write down all the things I've learnt (I have a list), and then think about what I want to do next. @gork wdyt?

I just googled something for the first time in ages. It felt archaic. Grok has spoiled me forever.

I have fond memories of using jQuery. Such a great utility that made using JavaScript (and specially DOM manipulation) trivial. I also remember when there was no jQuery and that is how old I am 👴🏽

@izzynobre Sempre quis que tivesse uma versao de HoMM pra iOS ou algum console moderno. Um dos meus jogos favoritos.

Uma coisa q me entristece: ser o único brasileiro acordado que conheceu esse clássico dos joguinhos antigos de computador
