@GerritD It's a man on the street interview with a guy who has an interest in burnishing how bad ass his motorcycle raiders are at jumping flaming pits of broken glass.

@sweis only explanation I can think of is if "died" is like a hyperbole for failing/wiping out hard that might have been lost in translation. otherwise makes no sense

In this report on "AI Enabled Terrorism", the IS-WAP commanders facing a defensive trench "consulted AI for guidance on adapting motorcycle jumping techniques seen in a movie":

18 of them died attempting jumps over unnecessarily deadly practice pits.

Next, AI will help Boko Haram attempt to jump the Snake River Canyon in a rocket.

Claude Fable 5 will be available again globally tomorrow. After a series of productive conversations with the US government, we're redeploying the model with a new set of classifiers to target and block more cybersecurity tasks. In the near term, some routine tasks like coding and debugging will fall back to Opus 4.8. We’ll continue to refine these classifiers over the coming weeks to reduce false positives and better distinguish genuine misuse from legitimate requests. We’ve also begun drafting a consensus framework—with Amazon, Microsoft, Google, and other Glasswing partners—for assessing the severity of AI jailbreaks and how AI developers should respond to them. We invite other industry partners and model providers to join us in this effort. Finally, we’re scaling up our collaboration with the US government on model testing and safeguards. This will include pre-release access to models and safeguards for evaluation, information sharing on jailbreaks and misuse, and dedicated resources for joint research. Thank you to our users for your patience, and to our partners across the government, industry, and the research community who worked alongside us to make Fable 5 available again.

The only way to restore that trust is to return to the ideals that helped build American prosperity. A legal regime that is democratically created, transparent, fairly applied with due process, and based upon evidence. Please read the letter at freefable.org

I’ve seen the paper. It’s not a jailbreak. It was Defense Oriented Prompting (DOP), capabilities defenders need. My thoughts on the hasty Export Controls that made Anthropic pull Fable. If Nat defense is the goal, this just scored an own goal against us

Critics of DP in 2020 Census often cite a "Harvard study" as evidence against. Our rebuttal: arxiv.org/abs/2409.06801

For 19 years, GPS satellites have secretly broadcast a “numbers station” in their public signals. We decoded 12M messages: a 2011 flash where 31 of 32 satellites flipped in hours, “ghost” substrings repeating years apart, and a “TEXT” prefix spreading now. lsc-pagepro.mydigitalpublication.com/publication/?i…
