AMAZON CEO RAISED RED FLAGS ABOUT ANTHROPIC’S MOST POWERFUL AI BEFORE THE U.S. GOVERNMENT PULLED THE PLUG Amazon CEO Andy Jassy reportedly raised concerns about Anthropic’s Claude Mythos model with U.S. government officials before this week’s extraordinary government crackdown, according to reporting from TechCrunch. The disclosure adds a significant wrinkle to what is already one of the most consequential regulatory moments in the short history of AI. Amazon is Anthropic’s largest cloud partner and investor, having committed tens of billions of dollars to the relationship. That makes Jassy’s reported intervention particularly striking. When your company’s biggest institutional backer is privately flagging concerns about your most capable model to government officials, the relationship between AI companies and their strategic partners is considerably more complicated than the public picture presents. On Friday, the U.S. government ordered Anthropic to immediately shut off access to Claude Fable 5 and Claude Mythos 5 for all users worldwide, citing national security concerns tied to a potential jailbreak. Anthropic complied under protest, publishing a lengthy blog post arguing that the underlying capability already exists in OpenAI’s GPT-5.5 and is routinely used by legitimate cybersecurity professionals. The government’s action is formally framed as an export control measure aimed at restricting foreign national access to the models. Anthropic says the directive effectively disabled the models for everyone. Jassy’s reported role in the events suggests that the pressure on Anthropic came from multiple directions at once, including from inside its own investment ecosystem. It raises hard questions about what it means for an AI company approaching an IPO to have powerful institutional backers who also maintain independent relationships with the same government deciding whether your products can remain available.
