Anthropic Co-Founder Jack Clark in Daily Government Talks, Publicly Proposes Technical Safety Framework as Path to Restoring Banned Fable 5 and Mythos 5

Anthropic co-founder Jack Clark disclosed that the company is in daily discussions with the Trump administration to resolve the national security concerns behind the June 12 global shutdown of Claude Fable 5 and Mythos 5, while publicly outlining Anthropic's proposed safety architecture. The framework would require mandatory pre-release testing and independent evaluation for frontier models trained above 10^25 FLOPs by companies with over $500M in AI revenue or $1B+ in AI R&D spending, with government authority to block deployment and escalating civil penalties tied to global revenue. The proposal is Anthropic's first public roadmap specifying what technical safeguards it would implement to satisfy the export control directive and restore access to its most capable models.
