Recurring claims
- Anthropic disabled Claude Fable 5 and Mythos 5 models worldwide after US government ordered suspension for foreign nationals due to national security concerns.
- A simple prompt 'fix this code' allowed bypassing Fable 5's safeguards, enabling it to suggest fixes for vulnerable code, raising security concerns.
- The US export control decision has sparked calls in the EU to reduce dependence on US AI technology and pursue tech sovereignty.
How sources frame it
