Anthropic Pulls Mythos 5 From Public After Government Restricts Use, Claiming 'Security Threat'
Summary from the AllSides News Team
Senior officials at Anthropic, the company that owns Claude and other artificial intelligence (AI) platforms, will meet with Trump administration officials on Monday to discuss reversing the federal government's shutdown of the company's two latest AI models.
Why The Models Were Shut Down: On Friday, the federal government restricted Anthropic's Fable 5 and Mythos 5 models from leaving the US, preventing non-US nationals from using the technology. The government cited "national security" concerns after Amazon warned that its researchers found ways for the AI to override its own safety regulations. Anthropic then shut down the models entirely, saying that it could not immediately separate eligible and ineligible users. BBC (Center bias) noted that this incident is the "latest this year," as the government marked Anthropic as a "supply chain risk" in March after the company refused to grant unrestricted access to its products for military use.
Anthropic's Response: According to CNBC (Lean Left), an Anthropic spokesperson said the company "received no communication about a national security threat" before the restriction was imposed. Anthropic also wrote in a blog that the vulnerabilities Amazon identified "all appear relatively simple, and we have found that other publicly available models are able to discover them as well without requiring a bypass."
How Could This Affect AI Development? Mythos was first released to a small, vetted group of organizations to test the model and determine what safety guardrails needed to be implemented. Just the News (Lean Right) wrote that before this, "the Trump administration has been relatively hands-off with regulating AI to avoid suppressing innovation and to stay competitive with China," as recent estimates suggest that the US has "six to 12 months before Beijing also gained access to a frontier model comparable to Mythos that could potentially be used as a cyberweapon." Anthropic argued that because the flaws in its models exist in other companies' models as well, "if this standard was applied across the industry, we believe it would essentially halt all new model deployments for all frontier model providers."
