Astral Codex Ten published Open Thread 454 as its weekly space for readers to discuss open topics and ask questions. The post also shares updates about a changed Brigham Young University meetup, newly translated Fatima documents, archived book reviews and a physician group focused on AI safety.
Astral Codex Ten has posted Open Thread 454, its weekly forum for readers to discuss any topic, ask questions and share information. The post also announces a changed time, date or location for the Brigham Young University effective altruism meetup, links to English translations of additional Fatima documents, and shares resources and outreach from the blog’s community.
The post describes the thread as the site’s weekly visible open thread, inviting readers to post about anything or ask random questions. It points readers to the blog’s unofficial subreddit, Discord server, bulletin board and in-person meetups around the world. The post says most of the site’s content is free, while some is available to subscribers.
One community notice says Brigham Young University’s effective altruism college meetup has changed its time, date or place. The post directs readers to the meetup list for the updated information, but does not provide the revised details in the announcement itself.
The thread also links to documents relating to Fatima, which reader Nikita Sokolsky says he has obtained from Portugal and translated into English. It credits Ana with handling work that required Portuguese proficiency. Other notices include Rob Ennals’s collection of earlier book-review contest entries in EPUB format and an invitation from Physicians For AI Safety for interested physicians to speak with the group and sign its open letter.
Updates for the ACX Community
The thread is primarily a community noticeboard, rather than a report of a single major event. Its practical value is in gathering several updates in one place: readers interested in the BYU meetup are told to check the revised listing, while people researching the Fatima documents can access the English translations through the linked site.
The post also makes resources easier to find. The EPUB collection brings reviews from earlier years of the blog’s book-review contest together, and the Physicians For AI Safety notice offers a contact point for physicians interested in AI safety. The group’s existence and invitation are reported as its own announcement; the thread does not establish the group’s size, activities or the contents of its open letter.
For readers, the thread’s broader role is to keep a dispersed online community connected through discussion spaces and local gatherings. The post also gives a brief account of the blog’s publishing schedule, which may help readers understand why recent output has been lighter.

A Weekly Forum With Notices
Open Thread 454 follows the format of Astral Codex Ten’s recurring open threads: an open-ended place for discussion, accompanied in this instance by a short list of community announcements. The source does not frame the post as a change to the site’s editorial direction or as a standalone investigation.
The notices cover separate projects and should not be treated as a single coordinated initiative. The meetup update concerns an in-person college group; the Fatima link concerns translated historical documents; the EPUBs concern the blog’s past review contests; and Physicians For AI Safety is seeking engagement from medical professionals interested in AI safety.
The source also includes an apology from the site’s author for publishing little recently and missing a Friday book-review entry. The author says they are busy and intend to make up the missed work after their schedule changes. No timetable is given.
“They exist, are interested in talking to any physicians interested in AI safety, and have an open letter that such people can sign.”

Details the Post Leaves Open
The announcement does not state the revised BYU meetup time, date or location; readers are directed to a separate list. It also gives no detail about the Fatima documents’ contents, number or historical status beyond saying they were obtained from Portugal and translated into English.
The thread does not describe Physicians For AI Safety’s membership, activities, or the text and intended audience of its open letter beyond its appeal to interested physicians. It also does not specify when the blog’s author expects to resume a fuller posting schedule or publish the missed book-review entry. These details are not confirmed by the source material.
