The Hard Fork episode covers a resurgence in AI safety concerns within the Trump administration, driven by Anthropic's Mythos model, alongside its cybersecurity implications discussed with Palo Alto Networks CEO Nikesh Arora, and a lighter roundup of tech miscellany.

Trump Administration Reconsiders AI Safety

The administration appears to be shifting from dismissing AI safety as "doomer fear-mongering" toward supporting pre-release reviews for powerful models. A rumored executive order would create an AI working group with tech executives and officials to explore oversight, including formal government vetting before public release. This reverses Trump's cancellation of Biden's similar executive order on his first day, which Republicans had criticized as anti-innovation and a risk of losing to China.

The pivot stems from Mythos, Anthropic's preview model shared with select groups including federal agencies. It excels at finding novel code vulnerabilities across programs, prompting fears of harm if released unchecked. Internal tensions include turf wars between the Center for AI Standards and Innovation (formerly US AI Safety Institute, or "Casey") and intelligence community advocates like NSA. The Pentagon exemplifies confusion: it designated Anthropic a supply chain risk for contract terms but is now implementing Mythos for vulnerability scanning.
