Introducing Grok 4.6.

It delivers frontier intelligence and is a significant improvement over Grok 4.5 at the same price.

Ladies and gentlemen, it's time to pass the torch and demote myself to my natural state: a poster. I'll be stepping back from leading product for 𝕏 and will continue on as an advisor.

Serving the X community has been the privilege of a lifetime. X is, and will remain, the most important communication technology in history. But running this app is a 24/7 job and it's now time for me to take a breather.

The app is seeing unprecedented growth in new users & engagement. We continue to break records every month. We've climbed 70 spots in the App Store since this time last year.

And in the last 400 days, we rebuilt almost every aspect of X: the Timeline, the Android app, onboarding, notifications, chat and more.

We also launched nearly 30 new products while protecting the integrity of the town square: becoming the first app to show Country-of-Origin on profiles and mounting defenses against AI bots. There's certainly much more work to be done, but our foundation is stronger than ever.

None of this would have been possible without the incredible team here. The next leaders will take X to even greater heights with @benjitaylor on design, @singhai on core product engineering and @dinkin_flickaa on mobile engineering -- among many other great people.

Thank you to Elon and the X team for welcoming me into the company. See you on the Timeline.

Ladies and gentlemen, today we're launching one of our biggest changes to 𝕏

Introducing Custom Timelines

This feature allows you to pin a specific topic to your home tab. With support for over 75 topics, you can dive deep into your favorite niche on X.

It's powered by Grok's understanding of every post with the algorithm's personalization—meaning every timeline is made just for you. And it works even better when it's a topic you already engage with.

This was a huge undertaking across many months, so we're excited for you take it for a spin.

We're giving early access to Premium subscribers on iOS (and Android coming very soon).

𝕏 has always been the best source of financial news for traders and investors. Billions of dollars are allocated every day based on what people read on Timeline.

Today we're launching our new Cashtags feature in the US and Canada on iPhone, bringing real-time financial data to X.

Here's how it works:

1. When you search for or post a cashtag (or contract address), X will automatically suggest matching stocks or crypto tokens, so you can select the exact asset you had in mind.

2. Anyone who taps a Cashtag will see posts mentioning it along with its price chart—without ever leaving X.

This ensures that you're always matched to the chatter for the right stock or token.

Cashtags are just the first step in our commitment to be the best destination for the finance and crypto community.

[XChat @chat]

Your encrypted chats deserve their own app.

Pre-order now: https://t.co/TM8Lk7AMGV

We're rolling out auto-translate worldwide to give posts in any language global reach on X.

The translations are powered by Grok and have improved substantially over the last couple months.

If you prefer to read in the original language, you can always turn off auto-translate by tapping the gear icon.

If you’re seeing a bunch of Japanese posts, here are some fun facts:

Japan has more daily active users and more time spent on X than any other country in the world.

Over two thirds of the country is monthly active on X.

X in Japan has one of the highest penetration rates of any social network in history.

[Nikita Bier @nikitabier]

The full power of Grok on the algorithm launches next week. It will be the most important change we've done on X.
