Elon Musk’s X Open-Sources Its Feed Algorithm Amid Crypto Content Disruptions

Elon Musk’s social media platform X has released the core architecture behind the algorithm that determines what users see in their feeds.

The move marks one of the first such disclosures ever made by a large social platform and comes as X faces growing pressure over content moderation, artificial intelligence, and crypto-related activity on the site.

X’s engineering team said the newly open-sourced system is built on the same transformer-based machine learning architecture used by Grok, the AI model developed by Musk’s xAI venture.

X Opens Its “For You” Algorithm, Admitting It Needs Major Fixes

The algorithm governs how posts are ranked in X’s “For You” feed, predicting user actions such as likes, replies, and reposts to determine which content surfaces most prominently.

Musk framed the release as a candid look at an imperfect system. In a post following the announcement, he acknowledged that the algorithm “needs massive improvements,” arguing that public scrutiny would help accelerate progress.

He added that X plans to publish regular updates every four weeks, accompanied by detailed developer notes explaining what has changed.

We know the algorithm is dumb and needs massive improvements, but at least you can see us struggle to make it better in real-time and with transparency.

According to technical documentation, the system relies on end-to-end machine learning rather than manually tuned ranking rules.

Written primarily in Rust and Python, the model retrieves posts from two sources, including accounts a user follows and a wider pool of content identified through machine-learning-based discovery.

These posts are then scored based on predicted engagement, with higher-ranked content appearing more frequently in feeds.

The transparency may also affect creators and crypto-focused accounts that rely heavily on X for reach.

Grok’s own analysis of the algorithm highlighted several factors that influence visibility, including engagement history, content freshness, author diversity, and negative signals such as blocks or mutes.

For creators, that clarity could reduce guesswork around what drives distribution, though it may also limit attempts to exploit ranking mechanics.

X Cracks Down on Crypto-Linked Engagement Apps

The timing of the release is notable. X has recently come under scrutiny after restricting API access for so-called InfoFi and engagement-reward projects, many of which were tied to crypto incentives.

The company said it would no longer allow apps that reward users for posting or interacting on X, citing concerns over AI-generated spam and manipulation.

Beyond crypto, X’s broader AI strategy has drawn regulatory attention, particularly in Europe, where authorities have raised concerns about Grok’s image-generation features.

The platform has since limited certain capabilities and introduced safeguards after investigations were launched.

As reported, X’s decision to clamp down on so-called InfoFi applications sent fresh shockwaves through the crypto market, dragging several tokens sharply lower and forcing a rethink across a niche that had grown tightly intertwined with the social media platform.

The immediate market reaction was led by KAITO, the token linked to the Kaito platform, which slid roughly 20% in a single day as investors digested what many saw as a structural threat rather than a short-term policy tweak.
