Either the algorithm hasn't been updated for over a year (unlikely) or the public version is abandoned.

The open-sourcing of the X's feed algorithm is a typical Musk's smokescreen.

First, while the code was open sourced, the configs and data that determines its behavior wasn't. Any researcher that has some knowledge of the matter will tell you this.

Second, that code was last updated in July 2023 [1]. News feed algorithms are updated regularly, especially around the time of US elections [2].

Sure it's open source but that doesn't mean the public repo is in any way up to date. Especially given that the repos only have a handful of commits from the few months after the repos were published and they haven't been updated in well over a year.
