The 𝕏 recommendation system is evolving very rapidly. We are aiming for deletion of all heuristics within 4 to 6 weeks. 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. This should address the new user or small account problem, where you post something great, but nobody sees it. We will also be adding the ability for you to adjust your feed temporarily or permanently just by asking Grok.

Winners Alliance and @X are partnering to bring you closer to your favorite cricket and tennis stars. ✨ We're excited to elevate athletes in the spaces where fans are highly engaged, creating a more dynamic and athlete-driven experience on X! Details: bit.ly/3Wp7oYl

Over the next week, I'll be dropping some small upgrades for power users. Most of these things were quick fixes that somehow fell through the cracks. Stay tuned.

It’s been quite the two weeks at X and xAi Last week me and our DACH Team led by @jolanta attended @dmexco, joined by a number of our other sales teams and our EMEA head of comms, Victoria Gillespie. We spent a few days at out booth at the conference meeting with clients, agencies and media. No matter who we met, everyone was fascinated by what was happening at X and the pace of innovation fueled by xAI and Grok. Last week also saw tennis icons and powerhouse siblings @Venuseswilliams and @serenawilliams debut a new, exclusive X Originals podcast series: Stockton Street. The premiere episode, aired on September 17. Closer to home we launched our first UK X Originals documentary series, @BurnleyOfficial ; Keepin the faith, brought to users by our sponsor, Sure for Men. A 20 part behind the scenes series that follows Burnley’s journey as they return to the Permier Leageue. Espisodes drop every two weeks on X, with episode two landing yesterday. Well done to @jonb0b and the @XUK Sales and Content Partnerships team for bringing this to market. The @xai team continued our remarkable progress to build the most intelligent and fastest AI on the and. Hot on the heels Grok 4, we launched Grok 4 Fast, delivering lightning speed and efficiency while outperforming competitors like OpenAI’s GPT-4o mini and Google’s Gemini 1.5 Flash. @nikitabier also announced that we are making our timeline algorithm open source and that our algorithm will be purely AI powered by the end of the year which means you will be able to adjust your feed dynamically just by asking Grok. And we will open source the algorithm every two weeks or so. Finally, I spent the last week in our Palo Alto office, meeting with our product and engineering teams, discussing how we continue to make X the number 1 platform for people in Europe to come to discover what’s happening and connect with the topics and communities that matter most to them. The pace at which the teams are working is quite something, and with xAI supercharging these efforts, there are great things to come for our users and partners in the months ahead. 🚀

Day 2 at DMEXCO with @jolanta and some of our DACH team. Here we go 🚀

Today, as part of our effort to make our platform transparent, we are open-sourcing the latest code used to recommend posts on the For You timeline. Our algorithm is always a work in progress. We will continue to refine our approach to surface the most relevant content to our community. github.com/twitter/the-algor…
