Astral Codex Ten’s Open Thread 454 is a weekly forum for readers to discuss any topic, accompanied by several community updates. The post notes a changed BYU meetup listing, newly translated Fatima documents, an archive of past book reviews and an invitation from Physicians For AI Safety.
Astral Codex Ten published Open Thread 454, its weekly open discussion post, alongside updates on an effective altruism meetup, translated Fatima documents, archived book reviews and a physician-led AI safety group. The post also says the author has been busy and expects to resume a fuller posting schedule later.
The post describes the thread as a place for readers to discuss any subject and ask informal questions. It points readers to the site’s unofficial subreddit, Discord, bulletin board and in-person meetups. The thread does not set a single topic or agenda for discussion.
Among the practical notices, the post says Brigham Young University’s effective altruism meetup has changed its time, date and location, and directs readers to check the meetup list for the revised details. It does not provide the replacement schedule in the post itself.
The post credits reader Nikita Sokolsky with obtaining additional documents from Portugal related to Fatima and translating them into English; it links to a site hosting the documents. It also says Rob Ennals collected book reviews from earlier years of the site’s annual contest into downloadable EPUBs. Physicians For AI Safety is introduced as a group seeking conversations with physicians interested in AI safety and signatures on its open letter.
Updates for ACX Readers
The thread combines a general reader forum with small but actionable community updates. Readers who attend the BYU meetup may need to consult the updated listing before making plans, while the document and book-review links make previously gathered material easier to access.
The Physicians For AI Safety notice is an invitation to a specific professional audience: physicians interested in AI safety can contact the group or consider signing its letter. The post does not describe the letter’s contents or claim that the group represents a broader medical consensus, so its significance here is as an outreach announcement.
The author’s note about limited recent writing also sets expectations for readers following the publication. The post says the author intends to make up for the reduced output after becoming less busy, but gives no timeline or specific planned pieces.

A Weekly Reader Forum
Open Thread 454 follows the format identified in the post as Astral Codex Ten’s weekly visible open thread. The invitation to talk about anything sits alongside links to reader-run and in-person community spaces, making the post both a discussion venue and a noticeboard.
The other items point to projects connected with readers and contributors: the Fatima document work involved translation from Portuguese, with the post thanking Ana for assistance on tasks requiring Portuguese proficiency. The archived EPUB reviews were collected by Rob Ennals, who the post identifies as the creator of this year’s book review contest site.
Astral Codex Ten’s post also notes that most content is free while some is subscriber-only, and includes a subscription link. It does not say that access to the open thread or the listed resources requires a subscription.
“This is the weekly visible open thread. Post about anything you want, ask random questions, whatever.”

Details Still Missing
The post does not state the updated time, date or location for the BYU meetup; readers are directed to the linked list. It also provides no publication date in the supplied source material, so the timing of the announcement cannot be specified more precisely here.
The source does not summarize the newly posted Fatima documents, describe the Physicians For AI Safety open letter, or state how many past reviews are included in the EPUB collection. It gives no schedule for the author’s return to more frequent writing. These details remain outside the information provided in the thread.
