Four Months After Pledge, X Algorithm Repo Has One Commit

Four months after Elon Musk pledged monthly open-source updates, X’s official xai-org/x-algorithm repository on GitHub contains a single commit and no follow-up developer notes.

Musk made the pledge on January 10, saying the code would appear within seven days and be refreshed every four weeks with detailed release notes. The repository went live on January 17 and has not been updated since that initial upload.

The repo lists four components and reports the codebase as roughly 62.9% Rust and 37.1% Python. None of the components shows a subsequent commit, and the developer notes Musk promised alongside each refresh have not appeared.

The published files include a final score formula but do not disclose the weights attached to predicted user actions that determine a post’s rank. The Phoenix module README states the transformer is “representative of the model used internally with the exception of specific scaling optimizations,” indicating differences between the sample code and the system running in production.

Observers note the released model trains on negative signals such as reports and blocks. Crypto users and community organizers have reported drops in reach over the same period. Ethan, a market watcher, wrote on X: ‘The algorithm is the worst it’s ever been. All I see is politics, rage bait, engagement bait and like 10% crypto content. Communities are dying and this app is becoming Instagram 2.0 when infact it’s best feature was the fact communities formed around topics and you stayed largely within that community on your feed.’

Ethereum co-founder Vitalik Buterin publicly questioned whether X could meet meaningful transparency standards before the repository was published. Some developers point to decentralized alternatives such as Farcaster, which publish full, forkable protocols that can be audited and run against production behavior, as an alternative to sample code that cannot be verified against the live system.

The January upload follows a 2023 release from the earlier twitter/the-algorithm repository that drew similar criticism before becoming inactive. The absence of promised monthly updates and release notes has left independent researchers with a partial view of how the platform’s recommendation system operates.

In his announcement, Musk wrote: “Critique of the X algorithm is welcome. There will be monthly updates of the latest algorithm to GitHub with release notes. As reminder, you can always choose no algorithm via the Following tab.” Developers, content creators and communities will watch whether the repository receives the promised refreshes in the coming weeks.
