We will make the new ๐ algorithm, including all the code used to determine which organic and ad posts are recommended to users, open source in 7 days.
This will be repeated every 4 weeks with comprehensive developer notes to help you understand what has changed.

@grok around the world But the expected update also relates to something Musk has been claiming he wants to do since he took ownership of Twitter in 2022, saying at the time that “making algorithms open source to increase trust” was part of his ambition for the site.
This latest transparency promise is probably the most comprehensive they’ve made with an actual due date, and comes with a quick timeline. He said in 2022, “Twitter will open source all the code used to recommend tweets on March 31,” giving itself a two-week window at that time, and the site actually released a GitHub repository on that date that included at least a snapshot of the recommendations algorithm. Most of the files in that repository are from that initial upload, although some appear to have been updated as recently as four months ago
This was a partial code release, and hardly satisfied everyone’s expectations of an open source social media platform. For example, a 2023 report that Musk had sought changes to the algorithm to increase the visibility of his own posts came from document leaks and anonymous interviews with X staff members, not just a review of the code. And when Musk hinted at changes he wanted to make in 2024, Mark Cuban asked him, “Can you post the expected algorithm source code before implementing them? So users can provide feedback?”
And it almost goes without saying that the site has been criticized as supporting and promoting right-wing opinions. A report last year shows that this apparent new bias is systematic. X was also one of the places where shocking, uncensored footage of Charlie Kirk’s murder spread rapidly last year.
Another possible reason for the sudden transparency: Last year, investigators in Paris, France began investigating possible fraudulent manipulation of the X algorithm, with Musk claiming the effort was “distorting French law to serve a political agenda and, ultimately, restricting free speech.”
This latest expected update seems to be a step closer to what most people mean by “open source.” Musk’s post about the change said that users can expect to see “the code used to determine which organic and ad posts are recommended to users” and that the release will be “repeated every 4 weeks with comprehensive developer notes to help you understand what changed.”
