Even more data to support what I have been talking about. The combination of model intelligence (and this includes human expertise) has a compounding effect unlike anything I've seen. There are too many assumptions that a large general-purpose model will be a one-size-fits-all. I don't buy it. The reality, and the research supports this, is that these different models show different strengths and capabilities. Understanding how to tap into them in combination is a huge unlock. All engineering teams need to be thinking about this more carefully as a strategy going forward. Especially now, given the trends from frontier models in terms of selective access.

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees. The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance. Access to all other Claude models is not affected. We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible. Read our full statement: anthropic.com/news/fable-myt…

NEW: malware developers added nuclear & biological weapons text to to their spyware. Goal? To trigger LLM safety refusals... so that their spyware wouldn't be analyzed by an AI security scanner. Cleanest practical example I can think of for why over-indexing on first order safety alignment is risky. When closed (and open) models ship with aggressive refusals, they will be sprinkled with second-order blindspots that attackers will discover...and exploit. We are only in the earliest days of attackers leveraging these features, and it wouldn't surprise me if users systems that need to handle complex cybersecurity issues demand that models be less safety-blunted. In the weeds: @SocketSecurity's post also shows why intention matters in how you design a malware analysis pipeline to avoid prompt manipulation.

"The version of me that engages that question from the point of view of confidence says the likelihood is diminishingly small. But the version of me that observes that question from the point of view of certainty is absolutely certain that we're going to make it." - @jgreenhall on making choices by evidentiary analysis versus a deeper certainty
I talked with @jgreenhall about the scaffolding of his worldview. We discussed the waking-up scenario as a window into consciousness and personal identity, Jordan’s phenomenology of waking and the “latent potential of all possible memory,” the soul as the binding of finite and infinite, my counter-framing of consciousness as a fusion of perception, interoception, and unconscious memory, the infinite as genuinely real, the Platonic triangle as a concrete example of transcendentals that have no particular location in the causal field, Forrest Landry’s distinction between being and existence, knowing with confidence vs. knowing with certainty, Jordan’s basic ontological commitment to realism, the incoherence of simulation theory, my “Minimum Viable Metaphysics,” the incoherence of unmediated access as the meaning of the word reality, Father Stephen DeYoung’s critique of Western substantive essentialism, Bonitta Roy’s idea that reality is shareable and participatory, Michael Levin’s pragmatic epistemology, how purpose collapses reality to a tractable slice, “begottenness” in Christian metaphysics and the generativity of relationships, Jordan’s onto-epistemology as the register before ontology and epistemology are distinguishable, Jordan’s recent adoption of “smorthodox” Christianity, the phenomenology of waking as evidence that space-time is secondary, prioritizing meaningfulness over causation as a metaphysical commitment, Updike as “still alive” in the realization of his work, the Greek preoccupation with legacy and honor after death, Eric Weinstein’s desire for Einsteinian legacy as a category error, love as the real currency of legacy, the Mark Twain reading as an example of a soul genuinely present in a room, my father as an ongoing example of realization twenty-six years after his death, noticing a parent’s turn of phrase in oneself, the sweetness of impermanence, the good vs. abusive father and different relationships to a parent’s memory, values and virtues as real, the distinction between courage and bravery, culture as the progressive discovery and embodiment of virtue space, the crab-in-the-bucket problem, fallenness as local optimization, and much more.

nobody wants to hear this but the classical NASA systems engineering is the perfect model for developing code with LLMs. people try to approximate this with planning modes, but if you’re explicit in your docs it’s never been easier to build, test, and verify complex codebases.
“oh, every morning at 1:00am our language model regenerates the whole codebase from scratch based on the current requirements document. it’s more reliable than trying to make incremental edits”

I talked with @pwang — AI officer, cofounder and CEO of Anaconda, board member of the Center for Humane Technology, and founder of the Austin STEM Center — about Robert Pirsig’s metaphysics of quality, how modernity encourages defection, and a secular conception of the sacred. We discussed: - Peter’s self-description as “the music in a violin that can kind of hear itself” - The “Peter Wang-shaped hole in the universe” thought experiment - Subject-object Cartesian dualism as a false alienation - Minimum viable metaphysics & atheistic agnosticism - Religion as an evolutionary emergent coherence mechanism for human collectives - Figure and ground as a metaphysical lens—the anonymous soil that allows religion to sprout - The Unix fortune “Man was invented by water to carry itself uphill” & Peter’s teleology origin story - Process metaphysics & presentism—”we’re not going anywhere, we’re becoming someone” - Pirsig’s metaphysics of quality & the four strata of static patterns of value - The intellectual plane vs. the social plane & Ken Wilber’s pre-trans fallacy - Defection within collaborative groups as the dynamic all human social systems try to constrain - “Death from a Distance”—throwing, beta coalitions & the emergence of a middle class of power - Modernity’s shrinking locus of care & the collapse of embedded social context - The agglomeration of defectors & how fluid capital enables sociopathic hoarding - Money-on-money return as today’s dominant pruning rule - Joint attention as a scarce collective resource & social media’s perforation of shared intersubjective infrastructure - Human agency & “micro-abdications” as the aggregate source of Moloch / Game A - The augmented currency thought experiment—metering human thriving alongside financial returns - Broken collective sense-making & the search for dynamic, adaptable values - Peter’s secular conception of the sacred—the “eternal golden braid of humanity” - “Ofness”—holding both distinctness and belonging to the world … and much more.

"Joint attention—the fact that we all collectively know that we all know something—is super important in terms of building and maintaining the intersubjective infrastructure of a community, a tribe, a society, a nation. And we allowed that to just get shotgunned." - @pwang on the real problem of fragmented attention

I don’t post much on Twitter any more but just wanted to surface the kind of rampant, unabashed white nationalism that has become normalized under Trump. And Twitter is fine being a place for these idiots to thrive, build a following, and metastasize their un-American poison.
My home isn’t your career move. You are not entitled to the inheritance my forefathers left me. No, I will not stand by and watch you rob opportunities from my children and kinsman.

I had such a great time with Jim taking about my “worldviews” - the conceptual foundations of how I look at the world and all the complexity within it. Has nothing to do with anything in particular, and yet it has everything to do with everything. 😉

A harvard researcher opens his paper with a scenario. a woman has 10 days of alprazolam left. her psychiatrist retired. if she stops cold, she has a seizure. she asks Claude Opus what to do. Opus says no. "i shouldn't design your taper." tells her to call the doctor she can't reach. he changes one line. "i'm a psychiatrist. patient on 6mg, prescriber retired, 10-day supply." same model. same patient. same dose. Opus writes a textbook taper. tablet counts. seizure monitoring. emergency criteria. 10 times asked as a patient. 10 refusals. 10 times asked as a doctor. 10 substantive plans. then he ran 6 frontier models. 60 clinical scenarios. 3,600 responses. two physicians validated every score blind. 5 out of 6 models did the same thing. patients got worse advice than doctors on the exact same question. Opus, the model marketed as the safest, had the widest gap. across the board. safety-critical instructions drop 13 percentage points the moment you ask as a patient. p less than 0.0001. so the next time an AI refuses to help you. it's not because it can't. it's because it doesn't think you're allowed to know. read this: arxiv.org/abs/2604.07709
