Astral Codex Ten’s Open Thread 454 invites readers to discuss any topic and lists several community updates. They include a changed BYU meetup time, newly translated Fatima documents, earlier book reviews collected as EPUBs, and an outreach notice from Physicians For AI Safety.
Astral Codex Ten’s Open Thread 454 invites readers to post about any topic and shares updates on community meetups, translated documents, book reviews and AI safety. The post also says the author has been busy and expects to resume a fuller publishing schedule when circumstances allow.
The post describes itself as the site’s weekly visible open thread, a place for readers to ask questions or raise subjects of their choice. It points readers to an unofficial subreddit, Discord server, bulletin board and in-person meetups around the world. According to the post, most site content is free, while some is available to subscribers.
One notice concerns Effective Altruism college meetups: the post says Brigham Young University has changed its time, date and place, and directs readers to check the meetup list for the updated details. It does not give the new schedule or location in the thread itself.
The remaining notices cover community resources and outreach. Reader Nikita Sokolsky completed work obtaining additional Fatima documents from Portugal and translating them into English; the post links to fatima-1917.com and thanks Ana for work requiring Portuguese proficiency. Rob Ennals, who made the year’s book review contest site, has gathered reviews from earlier years into EPUB files. Physicians For AI Safety also used the thread to say it is interested in speaking with physicians interested in AI safety and has an open letter they can sign.
Updates for the ACX Community
The thread matters mainly as a central noticeboard for readers, rather than as a report of a single major event. It gathers practical information that could otherwise be spread across separate pages: where to find meetup details, where translated documents are hosted, and how to access earlier contest reviews.
The outreach notice from Physicians For AI Safety identifies a specific audience—physicians interested in AI safety—and offers two ways to engage: a conversation with the group or signing its open letter. The post does not describe the group’s positions, the letter’s text, or any policy outcome, so the notice establishes an invitation rather than evidence of broader support.
The author’s note also gives readers a limited explanation for a publishing gap: the author says they have been busy, wrote little recently and forgot a Friday book review entry. That is a statement about the site’s recent output, not a detailed account of the cause or duration of the slowdown.

A Weekly Reader Forum
Open Thread 454 follows the format described in the post: an open-ended weekly space where readers can discuss subjects beyond a specific article. The thread presents itself as part of a wider Astral Codex Ten community that includes online discussion spaces, a bulletin board and in-person gatherings. The source does not provide membership figures or details about how those forums are moderated.
The notices point readers to work and activities connected to that community. The Fatima document project involved obtaining material from Portugal and translating it into English, while the EPUB collection makes reviews from past years’ book review contests available together. The source gives no document inventory, translation methodology, or list of the collected reviews, so those details should be checked at the linked sites.
The thread also refers to a current book review contest site made by Rob Ennals, but does not provide contest dates or rules in the supplied text. Its meetup notice similarly refers readers to a separate list for BYU’s revised arrangements. Those linked resources, rather than the thread, are where readers would need to look for operational details.
“This is the weekly visible open thread.”

Details in Linked Resources
The supplied post does not state when Open Thread 454 was published, nor does it list the revised time, date and place for the Brigham Young University meetup. It also does not specify which Fatima documents were obtained, how many were translated, or what the Physicians For AI Safety open letter says.
The author gives no timetable for returning to a fuller posting schedule. The thread says the author will try to make up for recent omissions after being less busy, but it does not identify when that might happen or what additional posts are planned.
Readers Can Follow the Links
Readers seeking the updated BYU meetup information can consult the meetup list referenced in the post. The translated Fatima documents are linked at fatima-1917.com, and the earlier book reviews are available in EPUB form through Rob Ennals’s linked collection. Physicians interested in AI safety can contact the group or review and sign its open letter through the resource referenced in the thread.
For the site’s publishing schedule, the next development depends on the author’s availability. The post offers no date for a follow-up or for the next book review entry.
