“Grok will literally read every post… to match users with content they’re most likely to find interesting.” – Elon Musk

On the 17th, X adjusted profile info and bolstered encryption, hinting at secure chat to curb fake engagement. Full Xchat launched November 14.

August monthly active users topped 600 million. October saw lively discussions on Virginia and New Jersey state elections.

Grok-powered algorithm tweaks were teased in October. Payments and AI enhancements expected by year-end.

“You should notice rapid improvements in the quality of your timeline almost every week,” Elon posted on X Saturday, adding, “We are also switching advertising recommendations to use the same Grok/AI system as organic posts, so quality of ads will get radically better.”

In October, Elon revealed the platform’s shift: “Grok will literally read every post and watch every video (100M+ per day) to match users with content they’re most likely to find interesting.”

The X team at its core is engineers. When Elon stepped into the old Twitter building with David Sacks, when he first acquired it, he found a merch closet with magnetic lapel buttons that said “I’m an Engineer,” and this concept was hilarious, who needs a button like that, as time passed, Elon structured X to be a TRUE place for great engineers, and they certainly are not wearing buttons.

To learn more about Jason Calacanis, see his Grokepedia bio, which is updated in real time, he’s been a good friend of Elon’s for years, “His candid, often contrarian public commentary—evident in co-hosting the All-In Podcast and advisory roles like during Twitter’s 2022 transition under Elon Musk—has amplified his influence but also sparked disputes with figures in tech and media.”
