X published the source code for its For You feed ranking system in the xai-org/x-algorithm repository on GitHub. The release makes publicly available the mechanism that selects and orders posts from followed accounts and external sources. Creator accounts on the platform described the move as the first time a major social network has disclosed its core recommendation algorithm.

𝕏 just open sourced the latest recommendation algorithm on GitHub
𝕏 is the only major social platform in the world to publicly open source its core recommendation algorithm
It is by far the most transparent social platform in the world right now

Positive users praise X for open-sourcing its recommendation algorithm due to added transparency and creator benefits, while negative users call the repo incomplete, misleading, and a PR stunt.

𝕏 just open-sourced its For You algorithm.
This is one of the biggest transparency moves from any social platform.
Here’s the Grok breakdown:
X has released the latest "For You" feed algorithm to GitHub.
Moving the feed closer to a Grok-style AI ranking system than a rule-heavy social media sorter.
The system first gathers posts from accounts you follow through Thunder, then adds outside posts through Phoenix, which searches for content that looks relevant even if you do not follow the author.
Ranking now behaves less like a checklist of likes, reposts, and keywords, and more like a transformer model that reads the user, the post, and past behavior as one prediction problem.
Instead of asking “is this post good,” the model predicts multiple possible actions, such as whether you might reply, like, repost, watch, or skip.
Thunder is the fast “people you follow” system.
It keeps a live memory-store of recent posts, replies, reposts, and videos from users, then quickly pulls posts from accounts you follow when your For You feed is built. It is basically the in-network candidate source.
Phoenix is the AI recommendation system.
It has 2 jobs: first, Phoenix Retrieval finds outside posts from the global X corpus using similarity search, and then Phoenix Ranking scores both followed-account posts and outside posts using a Grok-based transformer model.

Final takeaway:
The new algorithm wants to show people content they will actually enjoy engaging with. Stop chasing hacks. Focus on creating content worth interacting with.
If people reply, repost or spend time on your posts, the system notices.
How the new algorithm actually works:
It uses a Grok based transformer that analyzes your real engagement history. It predicts actions like replies, reposts, video views and dwell time.
It also heavily punishes negative signals such as blocks, mutes and not interested.
Quick practical tips:
→ Post videos when it fits → Ask questions that spark replies → Avoid very similar posts back to back → Focus on what makes people stay → Keep each post focused on one clear value
What you should avoid:
→ Clickbait that tricks people → Low quality or repetitive content → Posting too much similar content in a row → Trying to game the system with old tricks
Negative reactions now hurt reach significantly.
What you should do:
→ Create content that gets real replies and reposts → Use video and strong visuals → Make content people want to watch longer → Build genuine connections with your audience → Keep topics clear for better discovery
Key mindset shift:
Old algorithms rewarded volume and tricks. This one rewards genuine engagement and reduces reach when people react negatively. Quality beats quantity. Real interaction beats vanity metrics.
The entire problem is laid out in your post, Dogan. I’m a Jewish pro Israel account. We are outnumbered 100-1, maybe even more, on X. Just me posting anything about anything gets blocks and mutes and mass reporting. I can’t stop that because it has nothing to do with what I’m posting and simply the fact that I even exist. And the fact that X punishes this when it is out of our control only compounds the problem for all Jewish and pro Israel accounts. These negative impacts should be put in context, but you don’t do that. So we can never win.
Nobody is trying to game the system. We’re just trying to have a voice on what is meant to be the only open platform. But yet it’s no different to any other because you allow exactly the same behavior as all the others.
So basically there is nothing I or any other account in my position can do. And X continues to allow it without even trying to understand what’s going on.
@doganuraldesign TikTok steals your attention span. Instagram steals your self-esteem.
X at least gives European regulators something productive to investigate every morning

Short Summary Breakdown 👁️🗨️
X has open-sourced its For You algorithm.
Here’s the key takeaway:
How it works:
- The algorithm is now powered by a Grok-based transformer.
- It heavily weighs real engagement.. replies, reposts, video views, and dwell time (how long people actually stay on your post).
- It strongly punishes negative signals... blocks, mutes, and “Not Interested” clicks hurt reach significantly more than before.
What this means for creators:
Do this:
- Focus on content that gets genuine replies and reposts
- Use **video** when it makes sense - Create posts people actually want to stop and watch/read
- Build real connection with your audience
Avoid this:
- Clickbait and low-quality content
- Posting too much repetitive or similar content
- Trying to game the system with old tricks
Bottom line:
The algorithm is moving toward quality and real engagement over volume and tricks. Negative reactions now cost you more, and genuine interaction is rewarded more than before.
It’s a shift toward showing people content they’ll actually engage with, rather than just maximizing time spent on the app.

@XFreeze Created a Visual mapping of the new Algo.
@doganuraldesign The block,mute part seems like a questionable metric. People block and mute over ideological differences not quality of content. This needs to be re-evaluated.
@XFreeze @elonmusk When it figures out why one post gets 5K and exact same post gets 100K, I will be impressed
@doganuraldesign That is great, now let everyone customize the code for their own "For you Custom" tab, or something like that.
