Elon Musk: X's New Algorithm Will Be Made Open Source in Seven Days (msn.com) 90

"We will make the new ð algorithm...open source in 7 days," Elon Musk posted Saturday on X.com. Musk says this is "including all code used to determine what organic and advertising posts are recommended to users," and "This will be repeated every 4 weeks, with comprehensive developer notes, to help you understand what changed."

Some context from Engadget: Musk has been making promises of open-sourcing the algorithm since his takeover of Twitter, and in 2023 published the code for the site's "For You" feed on GitHub. But the code wasn't all that revealing, leaving out key details, according to analyses at the time. And it hasn't been kept up to date.
Bloomberg also reported on Saturday's announcement: The billionaire didn't say why X was making its algorithm open source. He and the company have clashed several times with regulators over content being shown to users.

Some X users had previously complained that they were receiving fewer posts on the social media platform from people they follow. In October, Musk confirmed in a post on X that the company had found a "significant bug" in the platform's "For You" algorithm and pledged a fix. The company has also been working to incorporate more artificial intelligence into its recommendation algorithm for X, using Grok, Musk's artificial intelligence chatbot...

In September, Musk wrote that the goal was for X's recommendation engine to "be purely AI" and that the company would share its open source algorithm about every two weeks. "To the degree that people are seeing improvements in their feed, it is not due to the actions of specific individuals changing heuristics, but rather increasing use of Grok and other AI tools," Musk wrote in October. The company was working to have all of the more than 100 million daily posts published to X evaluated by Grok, which would then offer individual users the posts most likely to interest them, Musk wrote. "This will profoundly improve the quality of your feed." He added that the company was planning to roll out the new features by November.

    The creators of rival social networks like Mastodon can now get the code, review it, and make sure they never, ever, do anything remotely similar.

    • Releasing the source code will be useless, of course, since he already said that it's using Grok, an AI.

      Unless you know what's internal to Grok (and its training data), the quick summary of the key part of the source is "feed user information into black box. Return results from black box."

    • Funnier of the two Funny comments, but the story had so much potential for humor. Even if I'm allergic to all things Musk?

      Not worth the laugh, but I have delusions of an updated Mexican beer commercial with a script something like this:

      "I don't always starve two thousand people to death each day. Oh wait, on average I do."

      "He's the most psychopathic man in the world."

    The curly "d" with a cross appears to be a lower case Eth [wikipedia.org], which will be known to Slashdot's Icelandic, Middle English, and Old English readers. Just like smart quotes get turned into Angstrom symbols, Slashdot transforms the fancy "X" into something unexpected!
    • Appears as a lowercase o with a tilde over it to me. Why can't they just use a regular uppercase X and be done with it?

    Per TFS:

    In September, Musk wrote that the goal was for X's recommendation engine to "be purely AI" and that the company would share its open source algorithm about every two weeks. "To the degree that people are seeing improvements in their feed, it is not due to the actions of specific individuals changing heuristics, but rather increasing use of Grok and other AI tools," Musk wrote in October.

    It's one thing to see the source code behind the recommendation engine. It's another to see the source code and training data that produce the AI models that are used by that engine. I wonder whether we're going to see the latter.

      I was wondering the same thing. Open-sourcing the algorithm code is great. But if it relies more and more on some AI "black box" to make the decisions, then that open code isn't going to be but so revealing. Still, it could be useful, since you would see what queries are (and are not) going to the AI and when/how. And what actions are taken with the responses.

      Grok's standing orders leaked out long ago, and are basically "do what Elon Musk would do". It gets trained on his posts.

      I left twitter and won't come back until that gets fixed and it's de-nazified.

    This is the code they are uploading to github, not necessarily the code they are using on Twitter. Nothing more!

      Correct. There is no reason to believe that ANY twitter code will be exposed to the public.

    Anyone who thinks that Elon's BS won't still be promoted in the recommended feed, I'll have a nice bride to sell you.

    He can show whatever code he wants. Doesn't mean that internally that's actually the one they run.

  • Does this include all the inputs to neural networks and other "AI" things that are being used to determine what you see in your feed?

    If it doesn't include the inputs (or where the inputs are somehow derived from user-specific data associated with your account, show you how to actually get those same inputs from your account data) then it is useless.

    They’ll “release” their code in the same way that the US government has “released” the epstein files.

    This is probably meant to distract from the grok-porn developments. Any traction on this issue will have to be done outside the US. Musk has purchased absolute immunity from the Trump organization, for basically anything. It’ll last until the current admin is out of office. I have mixed feelings about this. Regarding X, it’s being used for slimy purposes. For SpaceX, he’s using it to neutralize government opposition to Starship, and I’m 110 percent behind that specific effort.

    I don't know if this was Twitter's original source code and, after Musk bought the company, he changed the code. In any case, am sharing this because it's not mentioned in the new story that Twitter -- apparently -- already has shared their source code/

    That Twitter even before Musk would not automatically detect Nazis and white supremacists because when they wrote algorithms to do that it kept flagging US Republican politicians.

    This is because computers are very very good at making connections. And the Nazis and the Republicans both use the same dog whistles just a few steps removed here and there.

    The most famous example is welfare queen. Welfare was chosen as a way to reference blacks and queen is a way to reference gay people. It was a easy and effective way to say something bad about black people and gay people without actually just flat out saying it. That's a dog whistle.

    The problem is that computer algorithms are surprisingly smart when it comes to figuring out dog whistles because they can see the connections very very quickly without belonging to a specific group. Normally it takes quite a bit of time and quite a bit of immersion in politics before you recognize the dog whistle when you see it but a computer is going to do it instantaneously and without regard who is saying the dog whistle.

    So when a republican politician goes on a tirade about welfare Queens the computer knows what they're talking about and was flagging them as the white supremacist that they are.

    You can still find the articles about this on Google surprisingly. Search for something like "Twitter can't use an algorithm to detect Nazis because of Republican politicians" and you'll find them.

    Now to bring this back to the point of the article so I don't get modded off topic there is no way muskrat is going to properly open source the algorithm because it would open up that discussion again. It's going to be like the Epstein files where we see bits and pieces of it with a lot of obvious redactions

    • Here's the thing about "dog whistles". Ever wonder how you can "hear" them, when you aren't the supposed intended audience, but the actual audience doesn't hear them? It's because they aren't real. When you hear a commentator accuse someone of using a dog whistle, what you're actually hearing is an ad hominem attack from someone with nothing to say.
