U.S. government has ordered Anthropic, an AI firm,to block foreign nationals from accessing its latest software models,Fable 5 and Mythos 5. The directive came down Friday,forcing swift compliance. National security's at stake,they say .
Anthropic shared in a blog post that the order hit at 5:21 PM (21:21 GMT) with little detail on the security issues behind it. The ban affects not just foreigners abroad but also those in U.S.,including Anthropic's own employees .
Company had to clamp down on access fast . Fable 5,launched just days ago,uses tech from Mythos,a model known for spotting software vulnerabilities. U.S. authorities and some firms use it to plug security holes. But there's fear it could become a cyberweapon in wrong hands .
Mythos 5's full version stays off-limits to public,available only to government agencies and select corporate partners for boosting cybersecurity. Anthropic said it got limited info from government. They reviewed a report likely sparking this move,thinking it's about AI's limited ability to analyze and fix code errors.
Anthropic noted other models,like OpenAI's GPT-5.5,offer similar features. They disagree with restricting widely-used software over these issues,stating Fable 5's safety protocols passed extensive tests.
Earlier this month,Anthropic called for a pause among AI giants on developing advanced systems. They warned that AI's rapid growth could outpace human oversight. In a June blog post,they suggested slowing or pausing AI development might be wise.
This order's impact goes beyond Anthropic,highlighting broader tech industry fears over advanced AI risks. As AI landscape evolves,balancing innovation with security stays a pressing concern for companies and governments…
