This Week in AI: Fable Chaos Edition

The week started with the long-awaited release of Anthropic's Fable 5, a Mythos-class model that had been anticipated for months. By Friday evening, the US government had directed Anthropic to cut off access to all foreign nationals for both Fable V and Mythos V, after Amazon—initially unnamed—reported the situation. The host called it "a fairly fundamental way" the "tides of power in AI shifted." The recommendations at the end of this recap to go try Fable 5 no longer work, and a full emergency episode was promised for Saturday, June 13th.

Fable 5: The Model That Delivered

Fable 5 arrived with massive benchmark improvements, but the real question was whether it actually felt better to use. The host observed a clever narrative circulating: that AI had advanced to the point where normal people couldn't tell the difference between models anymore. Citrini Research tweeted, "I think we've reached the point where normal people can't really determine whether new models are better than previous ones. Like Fable doesn't seem that much better to me, but every 150 IQ person I know is like, wow, the singularity came sooner than I thought."
