Musk said third-party reviewers will verify that the running system matches the open source code. The move follows a 2023 release of the timeline algorithm, which has not been updated since, despite ongoing changes to the platform. The announcement covers all code with no exceptions.","whyItMatters":"The promise to open source X's entire codebase with third-party verification is a dramatic escalation from the 2023 algorithm release, but the company's failure to update that earlier code raises questions about execution.","webCardHtml":"\u003cp\u003eIn 2023, X released the source code for its timeline recommendation algorithm as promised. That code has not been updated since, even as the algorithm itself changed. Now Elon Musk says the entire X codebase will be open sourced, with no exceptions. A security review is underway, and once complete, all source code will be published. Musk also said third-party reviewers will be invited to confirm that the running system matches the open source code. \u0026#39;Trust through total transparency is the only thing that should be believed,\u0026#39; he said.\u003c/p\u003e","blueskyPost":"X's 2023 timeline algorithm release has not been updated since, despite ongoing platform changes.

The move follows a 2023 release of the timeline algorithm that was never updated.
