Elon Musk has announced plans to make the recommendation algorithm of X open source, a move he says is aimed at improving transparency and helping users better understand how content is shown on the platform. The announcement was made through a post on X, where Musk outlined how and when the algorithm code will be released.

According to Musk, the change marks a shift in how X communicates with developers and users about ranking, reach, and visibility of posts across the platform.

What Elon Musk said in his post

In his post, Musk wrote, “We will make the new 𝕏 algorithm, including all code used to determine what organic and advertising posts are recommended to users, open source in 7 days.” He added that this would not be a one-time exercise, stating, “This will be repeated every 4 weeks, with comprehensive developer notes, to help you understand what changed.”

The statement indicates that X plans to publish updated versions of its recommendation logic on a regular basis, alongside documentation explaining what has been modified between releases.

What an open-source algorithm means

By open-sourcing the recommendation algorithm, X is allowing developers, researchers, and users to inspect how posts are ranked and surfaced. This could help clarify long-standing questions around why certain posts gain visibility while others do not.

For developers, access to the code and change logs could make it easier to understand how engagement signals, relevance, and other factors influence recommendations. For users, it may offer more insight into how their actions — such as likes, replies, and scrolling behaviour — affect what appears in their feeds.

Impact on everyday users

For regular users, the immediate experience on X may not change overnight. However, increased transparency could lead to more informed discussions about content visibility, shadow-banning claims, and perceived bias in recommendations.

User feedback following Musk’s post shows mixed reactions. Some users welcomed the move as a step toward openness, while others raised concerns about feed relevance and content overload. By publishing frequent updates, X may also allow users and developers to track how tweaks to the algorithm influence timelines over time.

Why this matters for X

The decision to repeatedly open-source the algorithm suggests X is positioning transparency as a core principle of its platform strategy. If implemented as described, it could set X apart from other major social networks that keep recommendation systems largely opaque.

Over time, how clearly X communicates these changes — and how they affect real-world usage — will determine whether this move improves trust and user experience on the platform.
