Elon Musk (일론 머스크) said he would make the entire codebase of social media platform X open source after completing a security vulnerability review. He also plans to pursue a process for third parties to verify that the code used in the live service matches the published code.

On July 15 local time, blockchain outlet Cryptopolitan reported that Musk said on X, "As soon as the security vulnerability review is finished, I will disclose X's entire codebase without exception." He also presented a plan to allow external reviewers to directly confirm that the open-sourced code is identical to the code running on X servers.

The move is seen as a measure to raise transparency around X's post ranking exposure and content moderation methods. Criticism has continued that the platform's algorithm operates like a "black box," and Musk has also said several times that major improvements to the algorithm are needed.

X previously disclosed part of its "For You" recommendation algorithm on GitHub in May. The code released at the time included some core components such as a Grok-based ranking system and "Thunder" and "Phoenix Retrieval," which select post candidates.

The scope of the disclosure was limited. It focused on a small "mini" AI model rather than the full code applied to the live service, and excluded key elements such as training data and the advertising system.

Even so, developer interest was strong. The repository recorded about 20,000 GitHub stars in a single day. The latest announcement means expanding the disclosure target from parts of the algorithm to the platform's entire codebase.

Musk is reportedly considering a plan to disclose algorithm changes every four weeks through GitHub. The timing for the full code release has not been confirmed, and neither the completion date for the security review nor the actual release schedule has been presented.

An open-source strategy premised on security reviews is not new. In February, Musk said he would disclose all related code for X's chat function after completing strict security tests, but that work has also not been completed yet.

Meanwhile, xAI, which develops X's AI model, is also continuing a separate open-source strategy. xAI released the Grok 2.5 model through Hugging Face in August last year. The model size was about 500 GB, and it was reported to require at least 8 GPUs to run.

Some also point out that while releasing the entire platform code would increase transparency, it could also raise new security risks. That is because system structure, design methods and potential vulnerabilities would be exposed and could be used for malicious attacks. In particular, if security flaws are found in released code, the impact could be greater for a platform with a large user base like X.

In the end, assessments say the plan's success depends on how thoroughly the security vulnerability review is conducted and how far third-party verification proceeds after release. If the full code is disclosed and external verification takes place, it is expected to have a significant effect on operational transparency at major social platforms.
