US warned Anthropic of China breach, but firm refused to fix Fable 5 jailbreak, says David Sacks

Recent revelations by former AI czar David Sacks expose that the U.S. government warned Anthropic about a jailbreak in its Fable 5 AI model, yet the company refused to patch or remove it. The vulnerab... Read original →

The Fable 5 vulnerability reveals not just an AI security flaw but a new class of geopolitical risk emerging from the deep integration of AI infrastructure and semiconductor supply chains. Technically, reverse engineering of the Mythos model could compromise firmware-level security on 3nm chips—like NVIDIA’s H200 fabricated by TSMC—forcing cloud providers to redesign trusted execution environments. Compliance-wise, Anthropic’s refusal to patch effectively triggers U.S. export controls, raising global deployment costs for itself and partners like Amazon, potentially affecting advanced-node capacity allocation in Taiwan, China. Competitors such as OpenAI and Google will leverage this to push 'security-first' narratives, accelerating enterprise migration. NVIDIA may respond by hardening on-chip security modules to isolate model-layer risks. Within 18 months, expect U.S.-led mandates for joint AI-hardware audits, requiring cross-validation between training data logs and chip fabrication records—fundamentally reshaping trust in global AI infrastructure.
