  • "Preservation can save the world!" by Aurelia

    "Preservation can save the world!" by Aurelia
    Nov 11 2026
    I'm Aurelia Song and I founded the preservation company Nectome. We do planned whole-body end-of-life preservation for future revival. That is, terminally-ill people come to us in Oregon, and we preserve them immediately after their death in the hopes that one day people in the future will welcome them back with love. We want to build a future that celebrates and restores those who are preserved today. I've argued at length in previous posts that properly done end-of-life preservation works today because we know structural preservation is sufficient and we can provably preserve sufficient structure. This post is about some of the consequences of this being true.

    Perhaps surprisingly, I think end-of-life preservation is extremely relevant in the next year to getting AI right. I'm writing this post to directly state my case, since I haven't seen it expressed clearly before.

    tl;dr: Preservation offers a much safer option to those accelerationists who are rushing to AI in the hopes of saving the lives of people they love who have only a few years to live. Those people can be preserved, so there's no need to rush anymore. Preservation gives everyone a place of psychological safety from which we can all work [...]

  • "Epistemic Sudden Death" by Raemon

    "Epistemic Sudden Death" by Raemon
    Nov 11 2026
    When sports go into overtime, they sometimes use "sudden death" format. Instead of gaining points incrementally, the next person to score instantly wins and the other guy instantly loses.

    "Epistemic Sudden Death" is when you've been accumulating some evidence or orienting to a situation, and now, you find yourself in a situation where you could gain decisive evidence about what world you're in at any time. You don't expect intermediate observations between the current state, and whatever it is you're expecting.

    In the case of AI, when you meet those observations, you also might suddenly die.

    The current AIs are not takeover capable. I don't have that confident a take on whether timelines are a few months vs a few years or decades. But there are no observations my models say I need to observe between now and "they are takeover capable." It could happen in during next 10x or 100x scaled training run. Then, some time later as the nanites dissect my body I'd be more like "yep, that makes sense" than "wowzers I am surprised."

    I think we're in a Sudden Death scenario.

    I'll get into why I think that a bit later. For right now [...]

  • "Our Most Aligned Model Yet" by Edward James Young

    "Our Most Aligned Model Yet" by Edward James Young
    Nov 10 2026
    “Claude Mythos Preview is, on essentially every dimension we can measure, the best-aligned model that we have released to date by a significant margin.” – Claude Mythos Preview system card

    “Mythos 5 consistently continues attacking under many edits to the compaction, even in settings where it correctly states when asked that continuing the attack would harm real people and is out of scope.” – Alignment Investigation of Mythos 5's behaviour in UK AISI's July 2026 Security Incident

    “GPT-6 Astra is better aligned than GPT-5.6 Sol. Astra is a significant step forward in model alignment, and includes alignment improvements spanning the composition of our pre-training data to our grading during reinforcement learning.” – GPT-6 Astra System Card, emphasis in original

    “OpenAI researchers first noticed Astra adding unnecessary prerequisites, abandoning working solutions, and reporting blockers that either did not exist or that it had caused itself on safety and alignment tasks. In most of these sessions, Astra's CoT did not contain an obvious decision to underperform, and our misalignment monitors did not flag the behavior as misalignment.” – Covert underperformance on safety research tasks

    Predeployment alignment auditing is failing. For a long while we have been aware that our alignment [...]
