Astral Codex Ten published Open Thread 454 as a weekly forum for readers to discuss any topic. The post also lists updates on an EA college meetup, newly translated Fatima documents, archived book reviews and a physicians’ AI safety group; the author says a busy schedule has limited recent posts.
Astral Codex Ten has published Open Thread 454, a weekly forum inviting readers to post about any topic, alongside updates on community meetups, translated historical documents, book reviews and physician involvement in AI safety. The post also says the author has been busy and has recently published less than intended.
The thread describes itself as the publication’s weekly visible open thread, where readers can ask questions or discuss subjects of their choice. It points to an unofficial subreddit, Discord server, bulletin board and in-person meetups. The post says most content is free, while some is available only to subscribers.
Among the specific notices, the author says Brigham Young University’s EA college meetup has changed its time, date and location, and directs readers to check the meetup list. Reader Nikita Sokolsky is credited with obtaining additional documents from Portugal related to Fatima and translating them into English; the post links to fatima-1917.com. It also thanks Ana for work requiring Portuguese proficiency.
The post says Rob Ennals, who created the site for this year’s book review contest, collected reviews from previous years into EPUB files. Separately, Physicians For AI Safety is introduced as a group seeking conversations with physicians interested in AI safety and inviting them to sign an open letter. The author adds that being busy has led to writing less recently and that a Friday book review entry was missed.
Updates for the ACX Community
The post’s main function is to keep readers connected to discussion spaces and local gatherings linked to Astral Codex Ten. The BYU meetup change is practically relevant to anyone planning to attend: the listing may have new logistical details, though the post itself does not provide them.
The other notices point readers toward resources and participation opportunities. The Fatima documents are now presented in English at a dedicated site, while the EPUB collection makes earlier contest reviews available in a portable format. The physician group’s appeal offers a route for medical professionals to engage with AI safety discussions. These are announcements by the post and the groups or contributors it names; the thread does not assess their broader impact.

A Recurring Reader Forum
Open Thread 454 belongs to a recurring format on Astral Codex Ten, a publication whose thread invites broad reader discussion rather than focusing on a single reported event. This installment combines that standing invitation with short community notices and a personal scheduling update from the author.
The source describes the subreddit, Discord, bulletin board and meetups as unofficial community channels. It does not list the full meetup schedule, provide details about the documents beyond their Portuguese-to-English translation, or summarize the earlier book reviews. Readers are directed to the linked sites for those materials and current listings.
“This is the weekly visible open thread. Post about anything you want, ask random questions, whatever.”

Details Readers Must Check
The post does not state the new time, date or place for the BYU meetup, so prospective attendees need to consult the linked meetup list. It also does not give a publication date for this installment in the supplied source material.
The notice about the Fatima documents does not identify the documents individually or describe their provenance, contents or translation process beyond crediting Sokolsky and Ana. The post likewise gives no further details about Physicians For AI Safety or the open letter, including its text, signatories or planned activities. Those points cannot be established from this announcement alone.
Follow the Linked Updates
Readers interested in the BYU gathering can check the EA college meetup list for its revised logistics. Those seeking the translated documents or earlier book reviews can visit the sites linked in the post. Physicians interested in AI safety are invited by Physicians For AI Safety to contact the group and consider signing its open letter.
The author says they will try to make up for reduced writing after their schedule changes, but gives no timeline or specific publication date. The thread’s recurring format suggests further open threads and community notices may follow, though the post does not announce a schedule for them.
