The Wall Street Journal reports that discussions between Amazon's CEO and US officials led to the blocking of Anthropic's latest AI models (Fable 5 and Mythos 5) from broad public release, over national security concerns. The report comes after Anthropic had already globally suspended the models following a US government order.
The Wall Street Journal reports that Amazon CEO Andy Jassy's conversations with US officials were instrumental in the decision to block Anthropic's new Fable 5 and Mythos 5 AI models from public release. According to the report, the discussions highlighted national security concerns about the models' capabilities, specifically a narrow code-analysis vulnerability that could aid adversaries. The development adds a new layer to a story The Zioneer previously covered in two background reports: Anthropic initially suspended the models globally on June 8 after a direct US order, citing the technical impracticality of restricting access by citizenship alone. The WSJ report now suggests Amazon—a major investor in Anthropic—played a behind-the-scenes role in shaping the outcome. The full extent of Amazon's involvement and whether the US order was coordinated with the company remain unconfirmed.
