Amazon security research reportedly led to the White House's Anthropic Fable ban

Overview

According to the Wall Street Journal, the export control directive that led Anthropic to cut off access to Fable 5 and Mythos 5 was triggered in part by cybersecurity research from Amazon and conversations between Amazon CEO Andy Jassy and the White House. Amazon's paper reportedly claimed it used a series of prompts to get Fable 5 to produce information usable in cyberattacks. Anthropic disputes the characterization as a jailbreak, some security researchers back the company, and the episode adds to ongoing friction between Anthropic and the Trump administration.
