Josh You on X: "the pentagon is still on sonnet 4.5 BTW https://t.co/7wDGwOxTNi" / X the pentagon is still on sonnet 4.5 BTW https://t.co/7wDGwOxTNi

Anthropic says Claude Gov primarily runs on Sonnet 4.5. Pentagon specifically could be using an older model but Anthropic explicitly describes Gov with 4.5 as a national security product.

i'm curious about the resulting ecosystem, such as it were. I asked them if there were any earthworms and they said no but they have centipedes.

I've decided to commit to memory the square roots of the human population of the United States (~18,000) and of the world (~90,000). This will come in handy.... I think

I am, for instance, unsure how our strategic counter-parties react to a reality where - at any time, even in the middle of negotiations - the United States might suddenly decide to blow up your cabinet or abduct your prime minister, with relatively little warning.

Most of the time, most means more than 51%. In fact, this is probably the case well over 51% of the time. I'm at least 51% sure of this.
