Meanwhile me and opus working in the kernel
Kernel-pure success — clear_pending_isolation (the faithful cell-177 ND26 isolation, variable bit position) proves via ext i; simp [BitVec.getElem_and, Bool.and_assoc, Bool.and_self] with axioms [propext, Quot.sound], no native edge.

Where this lands: the foundational lane now spans eight distinct nondeterminism mechanisms (memory-ordering, scheduling, signal-masking, byte-marshaling, memory-layout, wake-ordering, and signal-isolation), with two bit-vector cells both kernel-pure — empirically narrowing the spike’s “reconstruction-weak zone”

ITAR TIME, BABY!
Woohoo, Silicon Valley is about to learn what a "US person" is, and they're not going to be happy about it.

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.

My formal verification project now has its first hostile-reviewer executable: a one-command Lean-kernel certificate that re-derives the composed determinism-core theorem, proves Z3/native out of the core, demonstrates non-vacuity with teeth, and prints the exact residual floor.

Claude Managed Agents can operate in a sandbox you control, on your own infrastructure or with any provider you choose.
Today we added new guides for @blaxelAI, @e2b, @googlecloud, @namespacelabs, and @superserve_ai, so you can choose the best fit for your use case.

Claude Fable 5 came out today. So we gave it a RimWorld colony.
7 Fable agents; defense, medical, research, construction, farming, social, mapping - running 3 colonists through a REST API mod. Real game, real time.
It fed everyone. It never built a house. 🧵1/10

okay, after a few hours of playing around with Fable i've determined it to be borderline unusable. wtf @AnthropicAI
every other request is getting rerouted to Opus. requests with NOTHING AT ALL to do with bio or cybersec are STILL getting flagged and rerouted. like 50-60%.
who the hell let this go live. this is atrocious. i understand the safeguards but you basically didn't even release a model, you released a braindead, nerfed model that can't even handle the simplest request without being told to nuke itself and use a different model. what are we even doing?
just don't even release it next time smh

Interesting decision here by the Anthropic team:
if you ask Fable (Mythos) anything related to cybersecurity or bio, it's gonna redirect you to Opus 4.8
! keep in mind when you inevitably start to see tweets from random twitter posters screaming "Fable sucks at cybersecurity!!"

Se o bater das asas de um beija-flor já parece desafiar os limites da natureza, o pulsar PSR J1748-2446ad leva essa ideia a uma escala cósmica. Enquanto o pássaro bate as asas cerca de 80 vezes por segundo, essa estrela de nêutrons gira 716 vezes no mesmo intervalo. Seu equador se move tão rápido que alcança aproximadamente 24% da velocidade da luz. O que é frenético na Terra torna-se quase imóvel diante de uma máquina cósmica como essa.
