Astral Codex Ten published a November 2026 links roundup spanning forecasts, essays, community news and internet curiosities. The author says the links have not each been independently verified and that readers often identify errors or misleading items, so several claims in the post should be treated cautiously.
Astral Codex Ten has published its November 2026 links roundup, a collection of short items about artificial intelligence, disaster forecasts, online debate and community life. The post’s author says they have not independently verified every link and warns that readers commonly identify two or three errors or misleading items in each roundup.
The most consequential items concern forecasts attributed to Sentinel, described in the post as an ACX grantee that forecasts global disasters. One forecaster reportedly put the chance of a rogue AI exfiltrating its model weights at 25% over the next 12 months. The post does not provide the forecast’s underlying assumptions, definition of “rogue AI” or method for judging whether such an event has occurred.
The roundup also relays a warning from Sentinel-affiliated forecaster @belikewater that California is predicted to have a much rainier-than-normal winter. The forecaster reportedly cited a 2.5% chance of a major flood. The author says an AI forecasting system translated that into estimated chances of floods causing at least $10,000 in damage to 100,000 homes or to one million homes, and reports a 5% forecast for an ARkStorm that year, against a stated 1% baseline. Those figures are presented secondhand; the post does not include a full forecast specification or independent assessment.
Other entries point readers to an essay by Clara on what a world without work might look like, an article questioning UFO claims, and discussion of the lab-leak debate. The author also describes a reported NVIDIA agreement to acquire Hugging Face for $12.9303 billion, saying the unusual price encodes the decimal value of the hugging-face emoji. The roundup offers no deal documentation or separate confirmation of the transaction.
Forecasts Carry the Biggest Stakes
The roundup’s forecasts draw attention to risks that can be difficult to communicate: events with relatively low stated probabilities but potentially serious consequences. A forecast is not a finding that an event will happen. The reported 25% AI-risk estimate and California flood probabilities should be read as judgments by named forecasters, not established outcomes or official warnings.
For California readers, the post’s practical takeaway is to pay attention to seasonal rain preparation, including roofs and gutters. But its flood scenarios are not a substitute for local emergency guidance, and the post does not identify a government agency issuing a warning. The AI item similarly raises questions about how forecasters define and monitor model-weight exfiltration, rather than documenting that such an incident has taken place.
The roundup matters in another way: it gathers links from several fields for an audience that may not encounter them elsewhere. Its own caveat makes verification part of the story. Readers should distinguish the cited source material from the author’s commentary and check original reporting or forecast pages before relying on specific claims.

How the Monthly Roundup Works
The post follows a recurring format: brief links accompanied by the author’s reactions, jokes and suggested context. Entries range from factual claims to interpretations and personal opinions. The author explicitly cautions that links are not checked individually and says commenters typically find two or three inaccurate or misleading items in each post. They say they correct issues when they notice them, but cannot guarantee every correction will appear before a reader sees the page.
That caveat applies especially to the numerical forecasts, which need definitions, time windows and baselines to be interpreted properly. In this roundup, the reported AI estimate has a 12-month horizon, while the California item compares a reported 5% ARkStorm forecast with a 1% baseline. The post does not provide enough methodological detail to independently evaluate how the probabilities were calculated.
The rest of the collection includes lighter material, such as a claim about an inhabited island covered by one house and wordplay involving names, alongside essays about status competition and social life without productive work. These entries are presented as links and commentary, not as a unified investigation or a set of independently established findings.
“I haven’t independently verified each link.”

Verification and Forecast Details
The source does not provide direct links to the complete methods behind the Sentinel-related figures in the supplied material, nor does it establish whether the reported forecasts have been independently checked. The terms “rogue AI,” “exfiltrating its weights” and “major flood” are not operationally defined in the roundup. The AI-generated damage scenarios are the roundup author’s account of an AI system’s interpretation, not an official forecast.
The post also leaves the reported NVIDIA–Hugging Face agreement unsubstantiated within the supplied text. The purchase price and emoji explanation should not be treated as confirmed deal terms without corroboration. More broadly, the author says corrections may be made after publication, so readers may encounter changes to individual items over time.
Check Original Links and Updates
The roundup’s author says they will correct errors as they become apparent and highlight important corrections later. Readers seeking to act on the California weather item should check current forecasts and preparedness guidance from relevant local and state agencies rather than rely on a probability repeated in a links post.
For the AI and acquisition claims, the next useful checks are the original Sentinel forecast pages and primary company or regulatory statements. The supplied source does not announce a scheduled update, a confirmed flood event, an AI incident or a completed acquisition. Those points remain open unless corroborating sources establish them.
Key Questions
What is the November 2026 links post?
It is an Astral Codex Ten monthly roundup of links and the author’s commentary on topics including AI, weather risk, essays and community news.
Does the post confirm a rogue AI will steal model weights?
No. It reports a forecaster’s 25% probability over the next 12 months. That is a forecast, not evidence that an incident has occurred or a guarantee that one will.
What does the roundup say about California flooding?
It relays a forecaster’s reported 2.5% chance of a major flood and additional estimates discussed by the author. The post does not give enough detail to independently assess the definitions or methods behind those figures.
Are all the links and claims independently checked?
No. The author explicitly says they have not independently verified each link and that commenters often identify two or three items that are wrong or misleading.
Does the source confirm NVIDIA bought Hugging Face?
The roundup says NVIDIA agreed to buy Hugging Face for $12.9303 billion, but the supplied material does not independently substantiate the agreement. The claim needs confirmation from company or other reliable primary sources.
